 Unusual uses of common drugs is a new vision to experience the hidden side in medications effect.  It is the indications that health care provider not used to deal with it. Some indications may be approved by FDA other indications may be not yet approved.

 Unusual uses of common drugs differ from off-label uses that some indications approved by FDA. health care provider awareness of these unusual indications leading to the best counselling to the patient and let him use these medications in best way, also give health care provider many choices in some critical cases.

 Unusual uses of common drugs open the health care provider’s mind towards a new ways to the effect of medications.

 A salicylate drug, often used as an analgesic to relieve minor aches and pains, as an antipyretic to reduce fever, and as an antiinflammatory medication.

 Aspirin also has an antiplatelet effect by inhibiting the production of thromboxane, which under normal circumstances binds platelet molecules together to create a patch over damaged walls of blood vessels. Because the platelet patch can become too large and also block blood flow, locally and downstream.

1-Aspirin used in reducing risk of preeclampsia

 Pregnant women at high risk for preeclampsia should take low-dose aspirin (75mg81mg) every day after their first trimester .

 Preeclampsia is a complex condition that occurs in pregnant women and involves an increase in blood pressure and excess protein in the urine after 20 weeks of pregnancy.

 Daily low-dose aspirin in middle and late pregnancy can significantly reduce the occurrence of preeclampsia among these women and it can lower the risk of preterm birth or low birth weight resulting from the pregnancy-related condition because aspirin helps blood flow between the placenta and the fetus.

Mechanism

 High or normal doses (>325 mg) block production of prostacyclin and thromboxane, and low-dose aspirin (60–83 mg) results in selective block of thromboxane production, and favors the prostacyclin (vasodilation) pathway.

 This provides the basis for the use of low-dose aspirin to forestall or prevent pregnancy-induced hypertension. Importantly, low-dose aspirin does Unusual uses of common drugs by Ahmed Yossef

not completely inhibit thromboxane and does not completely ‘spare’ prostacyclin. One group of investigators found that 81 mg of aspirin inhibited thromboxane by 75 percent, but also inhibited prostacyclin by approximately 20 %.

2-Topical Aspirin for Relief of Pain due to Herpes Zoster and Postherpeic Neuralgia

 Topical aspirin dissolved in chloroform is an effective means of reducing pain due to herpes zoster and post herpetic neuralgia in most patients. The locus of pain origin and analgesia induced by topical aspirin is most likely at cutaneous freenerve ending pain receptors. The mechanism responsible for the analgesic properties of aspirin is probably not the same as that responsible for its anti-inflammatory properties. Unusual uses of common drugs by Ahmed Yossef

3-Aspirin and Alzheimer's

 The Baltimore Longitudinal Study that appearing in the journal Neurology reported that the incidence of Alzheimer's was 45% lower for people who took aspirin for more than two years, than those who didn't. Unusual uses of common drugs by Ahmed Yossef

15

 This is not the first study to suggest that aspirin may be effective in combating the onset of Alzheimer's. Mechanism

 There are numerous theories about why it appears to work. For example, one theory is that Alzheimer's is caused by an inflammatory process in the brain. Taking an anti-inflammatory medication might then reduce the risk. Another theory is that with Alzheimer's, enzymes in the brain cause a breakdown of proteins. When this occurs, amyloid plaque is formed and disrupts brain activity. Perhaps aspirin and other antiinflammatory medications prevent this from occurring.

4-Aspirin for the prevention of colorectal cancer

 Aspirin has been studied as adjuvant therapy for colorectal cancer, with promising results. Earlier prevention studies demonstrated the efficacy of aspirin against the development of colorectal tumors prompting investigation into its potential treatment efficacy. Mechanism

 The proposed mechanism draws on the fact that certain colorectal tumors overexpress prostaglandin-endoperoxide synthase 2 -- better known as cyclooxygenase-2 (COX-2). Mutations of the sort seen in colorectal cancer are known to sustain tumor cell growth by preventing apoptosis. By blocking COX-2, aspirin therapy is hypothesized to suppress tumor growth.  Taking aspirin in doses as low as 325 mg per day reduces CRC risk also there is also strong evidence from secondary analyses of cardiovascular trials that daily doses as low as 75 mg per day may be effective.

Patient counselling

First 2 weeks of treatment: • Warm the drops to body temperature before you use them. • You may find that the first time you use the drops you experience a slight hot or burning type sensation - this is normal. • Put 2 drops in the affected ear / ears, every night for 2 weeks then STOP. -After the first 2 weeks of treatment you should then use as follows: • 2 drops of solution only in whichever ear itches, whenever it itches. If you have been advised to continue using the drops in the long term Unusual uses of common drugs by Ahmed Yossef

26

it is better to dilute them. This will not affect its ability to work: • Dilute the Betnovate with equal parts of sterile / cooled boiled water (50:50). Store the made up solution in your refrigerator for up to one month. Discard the made up solution after a month. • Do not use the drops more than twice a day.

.How to instil your ear drops

1- Lie on a bed with the ear to be treated uppermost. 2. Take a firm hold of the ear; pull it gently backwards, then up and away from the head. This will make the ear canal straighter, so Unusual uses of common drugs by Ahmed Yossef

that the drops go in more easily. Put the prescribed amount of ear drops into the ear canal. 3. Lie on your side for at least 5 minutes - time it by the clock. This gives the drops time to soak in. 4. Place a piece of cotton wool in the outer canal, just to prevent any of the drops running out. Remove the cotton wool after 20 minutes. 5. Sit up slowly. 6. If both ears need drops, wait for 10 minutes before treating the second ear. Reference Oxford University Hospitals NHShttp://www.ouh.nhs.uk/

 Bromocriptine is a dopamine agonist, it is indicated for Amenorrhea, female infertility, galactorrhea, hypogonadism, and acromegaly may all be caused by pituitary problems, such as hyperprolactinaemia, and therefore, these problems may be treated with this drug.

1-Bromocriptine in type 2 diabetes

(FDA APPROVED USE)

 In 2009, bromocriptine mesylate was approved by the FDA for treatment of type 2 diabetes as an adjunct to diet and exercise to improve glycemic control in adults.  Note:- it is not used to treat type 1 diabetes Unusual uses of common drugs by Ahmed Yossef

30

Mechanism

It's not clear how bromocriptine improves glycemic control in humans. But studies in diabetic animals show that boosting dopamine activity at a particular time of day can "reset" the biological clock to improve metabolism problems related to diabetes, according to VeroScience, the company that developed the first brand of bromocriptine for type 2 diabetes mellitus. Dose

The recommended dose is 1.6 mg to 4.8 mg administered once daily within two hours after waking in the morning and should be taken with food Reference http://www.rxlist.com/cycloset-drug/indications-dosage.htm http://www.drugs.com/cycloset.html http://www.webmd.com/diabetes/news/20090507/new-diabetes-drug-cycloset-approved

 The combined oral contraceptive pill (COCP), often referred to as the birth-control pill .it includes a combination of an estrogen (estradiol) and a progesterone (progestin). When taken by mouth every day, these pills inhibit female fertility.  Estrogen and progesterone combined in OCs act in a synergistic manner in the gonadotropin axis. They decrease the secretion of hypophysial-luteinizing hormone and follicle-stimulating hormone by negative feedback, thereby inhibiting ovulation.

1-Combined oral contraceptive in treatment of acne for women. (FDA APPROVED USE)

 Acne is triggered by an excess production of sebum. Sebum is an oil made by glands in your skin. Along with skin cells, sebum can clog pores and promote the growth of bacteria that contribute to acne. Androgens, a group of hormones that includes testosterone, stimulate your skin to produce sebum.  A woman's ovaries and adrenal glands normally produce a low level of androgens. Higher levels of androgens can lead to excess sebum.

Unusual uses of common drugs by Ahmed Yossef

43

Mechanism

 Estrogen and progesterone decrease the secretion of luteinizing hormone and follicle-stimulating hormone by negative feedback.  Gonadotropin inhibition by oral contraceptive reduce androgen production of ovarian theca cells and adrenal gland.  An additional anti androgenic effect of estrogens comes from their stimulation of liver production of sex hormone binding globulin (SHBG), a globulin that binds free-circulating androgens and reduces free available testosterone to peripheral tissues. Note:-

 Only three types of birth control pills have been approved by the FDA for treating acne.  ethinyl estradiol+ norgestimate,ethinyl estradiol+ drospirenone and ethinyl estradiol+ norethindrone  These three oral contraceptives have been approved for treating moderate acne in women who: Unusual uses of common drugs by Ahmed Yossef

44

 Are at least 14 or 15 years old, Have already started menstruating and Need contraception  Combination oral contraceptives may be used as second-line therapy in pubertal females with moderate-to-severe acne

 Birth control pills work on only one acne-related factor -- excess sebum. Doctors often prescribe other forms of acne treatment -- topical medications or antibiotics -- to be used alongside them for best results in clearing the skin.  Spironolactone may be used in combination with OCPs in women who have limited response to OCPs alone.

2-Oral contraceptive in treatment of hirsutism for women.

 Hirsutism is a common, often distressing condition in which a person develops excessive growth of hair

Unusual uses of common drugs by Ahmed Yossef

47

Causes of hirsutism

 In many cases, the exact cause of hirsutism is not known. However, there are several conditions that are known to cause hirsutism. These conditions include:  The natural production of male hormones (androgens). Women naturally produce androgen, however, if a woman's androgen levels are higher than normal, or if her hair follicles are more sensitive to androgens, she may develop hirsutism.  Polycystic ovarian syndrome (PCOS) is a common hormonal condition that causes a woman to produce too many androgens. Women with PCOS may also have acne, irregular or absent menstrual periods, diabetes, weight gain, and/or problems with fertility.  The hormonal changes of menopause may lead to increased facial hair (mustache and whiskers).  Hirsutism that occurs suddenly along with other male characteristics, such as a deeper voice, acne, or Unusual uses of common drugs by Ahmed Yossef

48

increased muscle mass, may be caused by a more serious condition, such as disorders of the adrenal glands or ovaries.  The following medications can cause hirsutism: Anabolic steroids,testosterone,glucocorticoids, minoxidil ,danazol and phenytoin . Mechanism

 Estrogen and progesterone decrease the secretion of luteinizing hormone and follicle-stimulating hormone by negative feedback.  Gonadotropin inhibition by oral contraceptive reduce androgen production of ovarian theca cells and adrenal gland.  An additional anti androgenic effect of estrogens comes from their stimulation of liver production of sex hormone binding globulin (SHBG), a globulin that binds free-circulating androgens and reduces free available testosterone to peripheral tissues.  Oral contraceptive can be used in combination with one of the antiandrogens or other forms of therapy.

3-Combined oral contraceptive Treat polycystic ovary syndrome (PCOS) problems

 Polycystic ovary syndrome (PCOS is one of the most common endocrine disorders among females. PCOS has a diverse range of causes that are not entirely understood, but there is strong evidence that it is largely a genetic disease  The most common immediate symptoms are anovulation, excess androgenic hormones, and insulin resistance. Anovulation results in irregular menstruation, amenorrhea, and ovulationUnusual uses of common drugs by Ahmed Yossef

related infertility. Imbalance generally causes acne and hirsutism. Insulin resistance is associated with obesity, Type 2 diabetes, and high cholesterol levels. The symptoms and severity of the syndrome vary greatly among affected women. Mechanism

 Oral contraceptive pills are typically the first line of therapy for management of irregular bleeding in women with PCOS who are not interested in conception.  Cyclic withdrawal of estrogen and progesterone leads to complete endometrial shedding and resolution of most abnormal bleeding.  Exposure to the progestin in oral contraceptives leads to reduction in the risk of endometrial cancer and hyperplasia. In addition, the steroids cause a decrease in LH levels and a subsequent decrease in androgen production. Unusual uses of common drugs by Ahmed Yossef

4-Combined oral contraceptive in treatment of Dysmenorrhea

 Dysmenorrhea is the medical term for pain with menstruation. There are two types of dysmenorrhea: "primary" and "secondary".  Primary dysmenorrhea is common menstrual cramps that are recurrent and are not due to other diseases. Cramps usually begin one to two days after a woman starts getting her period. Pain usually begins 1 or 2 days before or when menstrual bleeding starts and is felt in the lower abdomen, back, or thighs and can range from mild to severe. Pain can typically last 12 to 72 hours and can be accompanied by nausea, vomiting, fatigue, and even diarrhea. Common menstrual cramps usually become less painful as a woman ages and may stop entirely if the woman has a baby.

Unusual uses of common drugs by Ahmed Yossef

 Secondary dysmenorrhea is pain that is caused by a disorder in the woman's reproductive organs, such as endometriosis, adenomyosis, uterine fibroids, or infection. Pain from secondary dysmenorrhea usually begins earlier in the menstrual cycle and lasts longer than common menstrual cramps. The pain is not typically accompanied by nausea, vomiting, fatigue, or diarrhea. CAUSE OF DYSMENORRHEA 

Prostaglandins are chemicals that are formed in the lining of the uterus during menstruation. These prostaglandins cause muscle contractions in the uterus, which cause pain and decrease blood flow and oxygen to the uterus. Similar to labor pains, these contractions can cause significant pain and discomfort. Prostaglandins may also contribute to the nausea and diarrhea that some women experience.

DYSMENORRHEA SYMPTOMS

 The pain of dysmenorrhea is crampy and usually located in lower abdomen above the pubic bone (the suprapubic region); some women also have severe pain in the back or thighs. The pain usually begins just before or as menstrual bleeding begins, and gradually diminishes over one to three days. Pain usually occurs intermittently, ranging from mild to disabling Mechanism

 Combined oral contraceptive work by thinning the lining of the uterus, where prostaglandins are formed, thereby decreasing the uterine contractions and menstrual bleeding that contribute to pain and cramping. Women may choose to use NSAIDs and hormonal contraceptives simultaneously to control dysmenorrhea.  Obviously, hormonal methods of birth control do not make sense for women who are trying to become pregnant. However, women who are not Unusual uses of common drugs by Ahmed Yossef

actively trying to become pregnant usually have significantly less dysmenorrhea after using a hormonal birth control treatment for two to three months, even if the woman does not need to prevent pregnancy (eg, if the woman is not sexually active or if she or her partner has had a sterilization procedure).

5-Combined oral contraceptive in treatment of female pattern hair loss (androgenetic alopecia)

 Life cycle of hair is divided into three phases Anagen -- active hair growth that lasts between two to six years Catagen -- transitional hair growth that lasts two to three weeks Telogen -- resting phase that lasts about two to three months; at the end of the resting phase the hair is Unusual uses of common drugs by Ahmed Yossef

59

shed and a new hair replaces it and the growing cycle starts again.  As people age, their rate of hair growth slows Almost every woman eventually develops some degree of female pattern hair loss. It can start any time after the onset of puberty, but women tend to first notice it around menopause, when hair loss typically increases. The risk rises with age, and it's higher for women with a history of hair loss on either side of the family.  As the name suggests, androgenetic alopecia involves the action of the hormones called androgens, which are essential for normal male sexual development and have other important functions in both sexes, including sex drive and regulation of hair growth. The condition may be inherited and involve several different genes. It can also result from an underlying endocrine condition, such as overproduction of androgen or an androgen-secreting tumor on the ovary, pituitary, or adrenal gland. In either case, the alopecia is Unusual uses of common drugs by Ahmed Yossef

60

likely related to increased androgen activity. But unlike androgenetic alopecia in men, in women the precise role of androgens is harder to determine. On the chance that an androgen-secreting tumor is involved, it's important to measure androgen levels in women with clear female pattern hair loss.  In either sex, hair loss from androgenetic alopecia occurs because of a genetically determined shortening of anagen, a hair's growing phase, and a lengthening of the time between the shedding of a hair and the start of a new anagen phase. That means it takes longer for hair to start growing back after it is shed in the course of the normal growth cycle. The hair follicle itself also changes, shrinking and producing a shorter, thinner hair shaft — a process called "follicular miniaturization." As a result, thicker, pigmented, longer-lived "terminal" hairs are replaced by shorter, thinner, nonpigmented hairs called "vellus." Unusual uses of common drugs by Ahmed Yossef

61

 FIRST-LINE THERAPY — for female pattern hair loss (FPHL), topical minoxidil

Mechanism 

Estrogen and progesterone pills and creams are probably the most common systemic form of treatment for androgenetic alopecia for women in menopause or whose estrogen and/or progesterone are lacking for other reasons.

 Estrogens are indirect anti-androgens, and are sometimes used for the treatment of androgenetic alopecia in women in the form of a birth control pill. When used systemically, estrogens increase SHBG production, which binds to androgens, including testosterone, reducing their bioavailability. Topical estrogen compounds are also commercially available in Europe. Unusual uses of common drugs by Ahmed Yossef

62



Hair follicles have estrogen receptors and it is believed that topical compounds may act on the hair follicles as direct hair growth promoters as well as by antagonizing androgen activity. However, large clinical studies demonstrating efficacy are lacking and topical treatment is not generally available in North America. Notes

 Only low androgen index birth control pills should be used to treat hair loss. High androgen index birth control pills actually contribute to hair loss by triggering it or enabling it once it's been triggered by something else.  Low-dose combined oral contraceptives with minimal androgen effect. These contain ethinylestrodiol and desorgestrel, gestodene or norgestimate.

6- Combined oral contraceptive in treatment of osteoporosis in post-menopausal women (FDA APPROVED USE)

 Osteoporosis is a disease that weakens bones, increasing the risk of sudden and unexpected fractures. Literally meaning "porous bone," it results in an increased loss of bone mass and strength. The disease often progresses without any symptoms or pain. Generally, osteoporosis is not discovered until weakened bones cause painful fractures (bone breakage) usually in the back (causing chronic back pain) or hips.  Unfortunately, once you have an osteoporotic fracture, you are at high risk of having another. These fractures can be debilitating. Fortunately, there are steps you can take to prevent osteoporosis from ever occurring. Treatments can also slow the rate of bone loss if you have osteoporosis.

Dexamethasone and betamethasone in pregnancy

Dexamethasone and betamethasone used in pregnancy to 1- speed up a preterm fetus's lung development. 2- It helps prevent respiratory distress syndrome (RDS) and related complications following premature birth. Mechanism

-Betamethasone and dexamethasone cause an immature fetus's lungs to produce a compound called surfactant. A full-term baby's lungs naturally produce surfactant, which lubricates Unusual uses of common drugs by Ahmed Yossef

70

the lining of the air sacs within the lungs. -This allows the inner surfaces of the air sacs to slide against one another without sticking during breathing. Premature infants whose lungs have begun producing surfactant are more able to breathe on their own, or with less respiratory treatment, after birth. When it used?

Optimal gestational age for use of dexamethasone therapy is 31 to 34 weeks of gestation. But Betamethasone or dexamethasone is most effective if delivery occurs at least 24 hours after the first dose of the medicine has been given and less than 7 days after the last dose of the medicine. references http://www.webmd.com/…/antenatal-corticosteroids-for-fetal-… http://apps.who.int/…/…/cd004454_hofmeyrgj_com/en/index.html http://www.ncbi.nlm.nih.gov/pubmed/15022581 http://humrep.oxfordjournals.org/content/14/2/303.long

Domperidone is a peripheral, specific blocker of dopamine receptors. Domperidone is given in order to relieve nausea and vomiting; to increase the transit of food through the stomach as a prokinetic agent Through increase in gastrointestinal peristalsis.

Domperidone Increase Breast Milk Production

Domperidone causes the increased production of the hormone prolactin as a side effect to its normal uses. Prolactin is the hormone which stimulates the cells in the mother's breast to produce milk.

Unusual uses of common drugs by Ahmed Yossef

76

Mechanism

Domperidone increases prolactin secretion indirectly, by interfering with the action of dopamine. One of the actions of dopamine is to decrease the secretion of prolactin by the pituitary gland. Domperidone is generally used for disorders of the gastrointestinal tract and is not licensed for use as a stimulant for milk production, though this does not mean that it cannot be prescribed for this reason. Dose

Domperidone has no officially established dosage for increasing milk supply. Most published studies have used domperidone in a dosage of 10 mg 3 times daily for 4 to 10 days. Two small studies found no statistically significant additional increase in milk output with a dosage of 20 mg 3 times daily compared to a dosage of 10 mg 3 times daily and that women who failed to respond to the low dosage did not respond to the higher dosage.

77

Notes

Domperidone is not approved for marketing in the United States by the US Food and Drug Administration, but is available in Canada, Australia, UK and other countries. In some nations, including Australia, domperidone is used off label, based on uncertain and anecdotal evidence of its usefulness, as a therapy for mothers who are having difficulty breastfeeding. Effects in Breastfed Infants

One paper reported 2 studies. In one, 8 women received domperidone 10 mg 3 times daily from day 2 to 5 postpartum. In the other, 9 women received domperidone 10 mg 3 times daily for 10 days from week 2 postpartum. No side effects were reported in any of the breastfed (extent not stated) infants. Eleven women took domperidone 10 mg 3 times daily for 7 days to increase the supply of pumped milk for

their preterm neonates. No side effects were reported in their infants. Very small amount of Domperidone were detected in breast milk samples.

 Erythromycin belongs in macrolide antibiotics. Macrolide antibiotics slow the growth of, or sometimes kill, sensitive bacteria by reducing the production of important proteins needed by the bacteria to survive.  Antibiotic macrolides are used to treat infections caused by Gram-positive bacteria and Haemophilus influenza infections such as respiratory tract and soft-tissue infections.  The antimicrobial spectrum of macrolides is slightly wider than that of penicillin, and, therefore, macrolides are a common substitute for patients with a penicillin allergy. Beta-hemolytic streptococci, pneumococci, staphylococci, and enterococci are usually susceptible to macrolides. Unlike penicillin, macrolides have been shown to be effective against Legionella pneumophila, mycoplasma, mycobacteria, some rickettsia, and chlamydia. Unusual uses of common drugs by Ahmed Yossef

resulting in food remaining in the stomach for an abnormally long time.  Normally, the stomach contracts to move food down into the small intestine for additional digestion. The vagus nerve controls these contractions. Gastro-paresis may occur when the vagus nerve is damaged and the muscles of the stomach and intestines do not properly function. Food then moves slowly or stops moving through the digestive tract. Symptoms

 The most common symptoms of gastroparesis are the following  Chronic nausea (93%)  Vomiting (especially of undigested food) (68-84%)  Abdominal pain (46-90%)  A feeling of fullness after eating just a few bites (60-86%)  Other symptoms include the following: Unusual uses of common drugs by Ahmed Yossef

 Palpitations  Heartburn  Abdominal bloating  Erratic blood glucose levels  Lack of appetite  Gastro esophageal reflux  Spasms of the stomach wall  Weight loss and malnutrition  Morning nausea may also indicate gastroparesis. Vomiting may not occur in all cases, as sufferers may adjust their diets to include only small amounts of food

Mechanism

 It enhances gastrointestinal motility by increasing the frequency of contractions in the small intestine or making them stronger, but without disrupting their rhythm. They are used to relieve Unusual uses of common drugs by Ahmed Yossef

gastrointestinal symptoms such as abdominal discomfort, bloating, constipation, heart burn, nausea, and vomiting.  They are used to treat a number of gastrointestinal disorders, including irritable bowel syndrome, gastritis, acid reflux disease, gastroparesis, and functional dyspepsia.  Erythromycin is the most potent prokinetic drug when given intravenously in the acute setting and is therefore useful in the initial management of hospitalized patients with severe gastroparesis. Dose

 Erythromycin 200 mg was infused I.V. initially followed by 250 mg orally 3 times/day 30 minutes before meals. Lower dosages have been used in some trials.  Orally 250-500 mg PO three times daily before meals. Unusual uses of common drugs by Ahmed Yossef

Notes:-

 Safety and efficacy were demonstrated in men between 18 to 41 years of age with mild to moderate hair loss of the vertex and anterior mid-scalp area. Life cycle of hair is divided into three phases

 Anagen -- active hair growth that lasts between two to six years  Catagen -- transitional hair growth that lasts two to three weeks  Telogen -- resting phase that lasts about two to three months; at the end of the resting phase the hair is shed and a new hair replaces it and the growing cycle starts again. As people age, their rate of hair growth slows What is Androgenic alopecia??

 Androgenic alopecia (also known as male pattern baldness) is hair loss that occurs due to an underlying susceptibility of hair Unusual uses of common drugs by Ahmed Yossef

follicles to androgenic miniaturization. It is the most common cause of hair loss and will affect up to 70% of men and 40% of women at some point in their lifetime. Men typically present with hairline recession at the temples and vertex balding while women normally diffusely thin over the top of their scalps. Both genetic and environmental factors play a role, and many etiologies remain unknown.  Classic androgenic hair loss in males begins above the temples and vertex, or calvaria, of the scalp. As it progresses, a rim of hair at the sides and rear of the head remains and rarely progresses to complete baldness. Mechanism

 Finasteride is a competitive and specific inhibitor of Type II 5α-reductase, anintracellular enzyme that converts the androgen testosterone into DHT.  Two distinct isozymes are found in humans: Type I and II. Each of these isozymes is differentially expressed in tissues and developmental stages. In Unusual uses of common drugs by Ahmed Yossef

93

humans, Type I 5α-reductase is predominant in the sebaceous glands of most regions of skin, including scalp, and liver. Type I 5α-reductase is responsible for approximately one-third of circulating DHT. The Type II 5α-reductase isozyme is primarily found in prostate, seminalvesicles, epididymides, and hair follicles as well as liver, and is responsible for two-thirds of circulating DHT.  In humans, the mechanism of action of finasteride is based on its preferential inhibition of the Type II isozyme. Using native tissues (scalp and prostate), in vitro binding studies examining the potential of finasteride to inhibit either isozyme revealed a 100fold selectivity for the human Type II 5α-reductase over Type I isozyme.  For both isozymes, the inhibition by finasteride is accompanied by reduction of the inhibitor to dihydrofinasteride and adduct formation with NADP+. The turnover for the enzyme complex is slow (t½ approximately 30 days for the Type II enzyme complex and 14 days for the Type I Unusual uses of common drugs by Ahmed Yossef

94

complex). Inhibition of Type II 5α-reductase blocks the peripheral conversion of testosterone to DHT, resulting in significant decreases in serum and tissue DHT concentrations.  In men with male pattern hair loss (androgenetic alopecia), the balding scalp contains miniaturized hair follicles and increased amounts of DHT compared with hairy scalp. Administration of finasteride decreases scalp and serum DHT concentrations in these men.  The relative contributions of these reductions to the treatment effect of finasteride have not been defined. By this mechanism, finasteride appears to interrupt a key factor in the development of androgenetic alopecia in those patients genetically Dose:-

 Finasteride may be administered with or without meals.  The recommended dose of PROPECIA is one tablet (1 mg) taken once daily. Unusual uses of common drugs by Ahmed Yossef

2-Finasteride in hirsutism

Notes

 In women, Finasteride used in hirsutism (only postmenopausal women with no chance of becoming pregnant.)  The main concern with finasteride, in women is the risk of ambiguous genitalia in male fetuses exposed to the enzyme inhibitor during the first trimester.

Introduction

 Hirsutism is a common, often distressing condition in which a person develops excessive growth of hair Causes of hirsutism

 In many cases, the exact cause of hirsutism is not known. However, there are several conditions that are known to cause hirsutism. These conditions include:  The natural production of male hormones (androgens). Women naturally produce androgen, however, if a woman's androgen levels are higher than normal, or if her hair follicles are more sensitive to androgens, she may develop hirsutism.  Polycystic ovarian syndrome (PCOS) is a common hormonal condition that causes a woman to produce too many androgens. Women with PCOS may also have acne, irregular or absent menstrual periods, diabetes, weight gain, and/or problems with fertility. Unusual uses of common drugs by Ahmed Yossef

98

 The hormonal changes of menopause may lead to increased facial hair (mustache and whiskers).  Hirsutism that occurs suddenly along with other male characteristics, such as a deeper voice, acne, or increased muscle mass, may be caused by a more serious condition, such as disorders of the adrenal glands or ovaries.  The following medications can cause hirsutism:  Anabolic steroids,testosterone,glucocorticoids, minoxidil ,danazol and phenytoin . Notes

 None of the drugs used to treat hirsutism have US Food and Drug Administration (FDA) approval for such use Mechanism

 Finasteride is a type of medication known as a 5alpha-reductase inhibitor. It works by preventing testosterone (an androgen) from turning into a stronger form of testosterone inside body’s cells. Unusual uses of common drugs by Ahmed Yossef

 Folic acid is a form of the water-soluble vitamin B9. Folate is a naturally occurring form of the vitamin, found in food, while folic acid is synthetically produced, and used in fortified foods and supplements.  Folic acid is itself not biologically active, but its biological importance is due totetrahydrofolate and other derivatives after its conversion to dihydrofolic acid in the liver. Unusual uses of common drugs by Ahmed Yossef

102

 Vitamin B9 (folate converted from folic acid) is essential for numerous bodily functions. Humans cannot synthesize folate; therefore, folate has to be supplied through the diet to meet their daily requirements.  The human body needs folate to synthesize DNA, repair DNA, and methylate DNA as well as to act as a cofactor in certain biological reactions.  It is especially important in aiding rapid cell division and growth, such as in infancy and pregnancy. Children and adults both require folate to produce healthy red blood cells and prevent anemia.  Folate occurs naturally in many foods, and among plants are especially plentiful in dark green leafy vegetables  A lack of dietary folates can lead to folate deficiency. A complete lack of dietary folate takes months before deficiency develops as normal individuals have about 500–20,000 µg of folate in body stores. Unusual uses of common drugs by Ahmed Yossef

103

 This deficiency can result in many health problems, the most notable one being neural tube defects in developing embryos.  Common symptoms of folate deficiency include diarrhea, macrocytic anemia with weakness or shortness of breath, nerve damage with weakness and limb numbness (peripheral neuropathy), pregnancy complications, mental confusion, forgetfulness or other cognitive deficits, mental depression, sore or swollen tongue, peptic or mouth ulcers, headaches, heart palpitations, irritability, and behavioral disorders.  Low levels of folate can also lead to homocysteine accumulation. DNA synthesis and repair are impaired, which could lead to cancer development.

Folic acid in male infertility

 Folic acid with zinc role in sperm quality and in sperm count  New research also shows that men who have a folic acid deficiency could notice a 90% reduction in their sperm count. If men suffering with partial infertility take folic acid it is proclaimed to increase the quality and quantity of their sperm.  Folate is necessary for fertility in both men and women. It contributes to spermatogenesis. Unusual uses of common drugs by Ahmed Yossef

105

Therefore, it is necessary to receive sufficient amounts through the diet to avoid subfertility.  Zinc and folic acid are elements essential to the formation of DNA and creation of sperm. However, the underlying mechanisms by which they affect spermatogenesis are not known. Combination of zinc and folic acid led to an increase in sperm concentration, having an endocrine-independent mechanism, as evidenced by an unchanged folliclestimulating hormone, testosterone, and inhibin.  According to many studies, Total normal sperm count found to be increases after combined zinc sulfate and folic acid treatment in both sub fertile and fertile men. Dose

 Folic acid once daily dose of 5 mg

Some other interesting folic acid facts

Folic acid from supplements and fortified products is absorbed easier by the body (100% from supplements). Eating foods high in folic acid is just as important as they also contain other important essential nutrients (estimated 50% absorption rate). We recommend a combination of both. Stress and illness increase the body’s need of folate. Folate works very closely together with vitamin B12 so a deficiency of one may result in a deficiency of the other, resulting in anemia (low levels of healthy red blood cells). If very high doses of folic acid supplements are taken, this can mask the symptoms of pernicious anemia. Therefore it's usually recommended to supplement both B9 and B12 together. The daily upper limit from supplements should not exceed 1,000 micrograms per day Unusual uses of common drugs by Ahmed Yossef

107

(usually only taken if prescribed by a health professional). This includes consuming large amounts of fortified food. This is to avoid risking neurological damage in case a B12 deficiency occurs. As well as the folic acid co-dependency with B12, the two vitamins also work along with vitamin c for the breakdown, utilization and formation of new proteins. Because folic acid is absorbed through the gastrointestinal tract, any conditions such as celiac disease, colitis, diarrhea, vomiting or any other disorder of the digestive system can result in a deficiency. This vitamin is primarily stored in the liver, so alcohol interferes with folate absorption and increases the excretion of the vitamin from the body. Folic acid can be destroyed by high temperatures, light exposure or from being left at room temperature for a long period of time. Unusual uses of common drugs by Ahmed Yossef

108

Only lightly steam vegetables or eat them raw whenever possible. *Please

note -The risk of folic acid toxicity is extremely low as this is a water soluble vitamin (although still possible). Caution is advised like with all supplements. Do not exceed the recommended dosage stated on the label.

 Gonadotropins (or glycoprotein hormones) are protein hormones secreted by gonadotrope cells of the anterior pituitary of vertebrates.  This is a family of proteins, which include the mammalian hormones follicle-stimulating hormone (FSH), luteinizing hormone (LH), placental chorionic gonadotropins hCG and eCG and chorionic gonadotropin (CG), as well as at least two forms of fish gonadotropins.  These hormones are central to the complex endocrine system that regulates normal growth, sexual development, and reproductive function. The hormones LH and FSH are secreted by the anterior pituitary gland, while hCG and eCG are secreted by the placenta. In women.

 Luteinizing hormone (LH) and follicle-stimulating hormone (FSH) are needed for egg production (ovulation). Early in the menstrual cycle, a woman Unusual uses of common drugs by Ahmed Yossef

with low hormone levels who is not ovulating can have daily human menopausal gonadotropin (hMG) or recombinant human FSH (rFSH) injections for an average of 12 days. If this helps develop mature follicles, the ovary is ready to ovulate. One dose of human chorionic gonadotropin (hCG) is then used to stimulate ovulation. In women

Gonadotropins may be used:

 To stimulate ovulation related to low natural gonadotropin or estrogen levels. (This is most commonly seen in women with excessive exercise or eating disorders.)  When clomiphene alone or clomiphene combined with another medicine has been ineffective for correcting irregular or no ovulation caused by polycystic ovary syndrome (PCOS).  For developing multiple egg follicles on the ovaries. Multiple eggs are harvested and used in assisted reproductive techniques such as in vitro fertilization or gamete intrafallopian transfer. Unusual uses of common drugs by Ahmed Yossef

 In combination with intrauterine insemination for couples with unexplained infertility when clomiphene has not worked. 1-Gonadotropins in men (FDA APPROVED USE)

 Gonadotropin therapy can treat low sperm counts caused by low levels of natural gonadotropins. Mechanism

 In men with low testosterone and FSH. LH stimulates the production of testosterone, and FSH promotes the formation of sperm. If a semen analysis, LH testing, and FSH testing suggest that abnormal hormone levels are preventing sperm production, these gonadotropins may be prescribed together to promote sperm formation. Unusual uses of common drugs by Ahmed Yossef

114

Dose

 The man gets an HCG injection 3 times weekly until blood testosterone level is within the normal range (this may take 4 to 6 months). Treatment continues with injections of HCG 2 times a week and hMG or FSH 3 times a week until the sperm count rises to normal levels.  Male Patients with Hypo-gonadotropic Hypogonadism  Pretreat with HCG (1,000- 2,250 USP Units 2-3 x/week) until serum testosterone within normal range (may require 3-6 months of treatment)  Treatment- FSH used in conjunction with HCG, FSH 150 international units SC 3 x/week  HCG 1000 USP Units (or dose to maintain normal serum testosterone levels) 3 x/week  If azoospermia persists, may increase FSH to maximum of 300 international units 3 x/week  May need to administer for up to 18 months for adequate response.

 Metformin is an oral ant diabetic in the biguanide class. It is the first- line drug of choice for the treatment of type 2 diabetes.  Metformin decreases glucose production in the liver, increases insulin sensitivity and enhances peripheral glucose uptake. It doesn't stimulate secretion of endogenous insulin.  Metformin decreases hyperglycemia primarily by suppressing glucose production by the liver (hepatic gluconeogenesis).

1-Metformin for Polycystic Ovary Syndrome

 The condition, polycystic ovarian syndrome, known as PCOS, is a common condition and is the commonest cause of ovulation disorders in women of reproductive age and usually present in late teens or early twenties.  (PCOS) characterized by the presence of many minute cysts in the ovaries, excess production of androgens and menstrual irregularities. Unusual uses of common drugs by Ahmed Yossef

130

 Polycystic ovarian syndrome can be found in apparently normal.  Polycystic ovarian syndrome is frequently associated with weight gain, excessive hair growth in the face and body, irregular and infrequent periods or absent periods, infrequent or absent ovulation, miscarriage and infertility.  Women with PCOS have both abnormally elevated luteinizing hormone (LH) secretion and hyperinsulinemia as a result of insulin resistance. The combination of hyper-secretion of LH and insulin causes ovarian androgen overproduction. In turn, ovarian androgen overproduction causes hirsutism and prevents normal ovarian follicle growth, preventing regular ovulation.  PCOS can be treated by lowering LH hypersecretion (oral contraceptive pills or GnRH agonist analogues) or by reversing the hyperinsulinemia that is caused by insulin resistance by Metformin or weight loss if she is overweight. Unusual uses of common drugs by Ahmed Yossef

131

Mechanism

 Many women with PCOS have decreased sensitivity to insulin, and their bodies overcompensate by overproducing insulin. Elevated levels of insulin are common in women with PCOS, whether they are obese or thin compared with weight matched controls. Some experts believe that this excess insulin is the underlying cause of PCOS because insulin stimulates androgen production and effects follicular development. As a consequence  Metformin lowers insulin, androgen, and cholesterol levels. It also improves metabolism in women who are insulin-resistant, it increase sensitivity of receptor to insulin and used in weight loss.  Metformin may help start ovulation in women with PCOS who have not responded to treatment with clomiphene. Some doctors may recommend taking Metformin in addition to clomiphene to start ovulation. Unusual uses of common drugs by Ahmed Yossef

Metronidazole in treatment of acne rosacea

 Metronidazole is used to treat acne rosacea (adult acne), a chronic condition in which the facial skin is inflamed and sores develop. Metronidazole decreases the redness and number of sores.  Metronidazole comes as a cream, lotion, or gel to be applied to skin, it usually used once or twice a day.

137

 Symptoms probably will improve within 3 weeks and continue to improve over the following 6 weeks or more.  For acne, wash the affected skin area with mild soap about 15-20 minutes before applying the medication. Apply a thin layer of cream, lotion and rub it gently into the affected area. references http://www.nlm.nih.gov/medlinepl…/druginfo/meds/a682244.html http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3401842/ http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3401842/ http://www.medscape.org/viewarticle/441986_13 http://www.medicinenet.com/metronidazole_cream/article.htm http://www.webmd.com/skin-problem…/rosacea-treatment-and-you http://www.nhs.uk/Conditions/Rosacea/Pages/Treatment.aspx

 Nifedipine is a dihydropyridine calcium channel blocker that primarily blocks L-type calcium channels. Its main uses are as an antianginal(especially in Prinzmetal's angina) and antihypertensive.  Nifedipine is on the World Health Organization's List of Essential Medicines, a list of the most important medication needed in a basic health system.

1-Nifedipine as a Tocolytic in Preterm Labor.

 Preterm labor remains a difficult issue in current obstetrics. Preterm birth still plays a major role in perinatal mortality and morbidity in developed countries, accounting for 60% to 80% of all Unusual uses of common drugs by Ahmed Yossef

neonatal deaths among infants without congenital anomalies.  Tocolysis is the use of medication to prevent preterm delivery. Preterm labor is defined as regular uterine contractions causing cervical dilation.  According to WHO, dihydropiridine class of calcium channel blockers (e.g. nifedipine and nicardipine) are preferred to other agents for stopping labor contractions.

Unusual uses of common drugs by Ahmed Yossef

141

Mechanism

 Smooth muscle tissue, like the uterus, needs calcium to contract. Nifedipine blocks the passage of calcium into certain tissues, relaxing the uterine muscles and smooth muscles of blood vessels throughout the body. Dose

 -According to New South Wales (NSW) health Australia (Quality & Patient Safety Committee)  Initial dose 20 mg orally stat, If contractions persist after 30 minutes further 20 mg orally may be given at 30 min intervals for a further two doses.  Maintenance 20-40 mg orally (four times daily) for up to 48 hours. MAXIMAL DOSE IS 160 mg per day.

 -According to several studies have ranged from 10 to 40 mg as an initial "one time" dose. Subsequent dosages have ranged from 10 to 20 mg every 6 to 8 hours as needed and tolerated to delay delivery. Unusual uses of common drugs by Ahmed Yossef

2-Nifedipine in treatment of Raynaud's disease

 Raynaud's phenomenon is a blood vessel disorder. When healthy people are in a cold environment, the tiny blood vessels in their skin constrict, or narrow. This is an effort by the body to conserve heat.  In people with Raynaud's phenomenon, that natural response to cold is exaggerated. The tiny blood vessels go into spasm, narrowing and reducing the blood flow to the affected areas. This response, called vasospasm, is seen most often in the fingers and toes. But it also can occur in the ears, cheeks and nose.  In some people, the constriction also can occur in response to emotional stress or a rapid change of temperature from warm to cool. Or, it may occur for no apparent reason.  The effect of this vasospasm can be dramatic and frightening. But it is temporary and rarely dangerous. Once the affected area is warmed, the blood vessels relax and expand. This allows more blood flow. Unusual uses of common drugs by Ahmed Yossef

144

 People who do not have any other symptoms or disease are said to have primary Raynaud's. People who have Raynaud's as part of another disease are said to have secondary Raynaud's.  Secondary Raynaud's is commonly linked to connective-tissue disorders, such as scleroderma and lupus. It also can result from blood vessel damage due to injury, frostbite or use of jarring machinery, such as jackhammers or chainsaws. Symptoms

 People with Raynaud's see and feel changes in their fingers and toes when exposed to cold. The skin blanches, or turns white, then blue. Fingers and toes can tingle or feel numb.  When rewarmed, the skin flushes pink or red. And there can be throbbing or soreness as the blood surges back into the tiny blood vessels.  People with secondary Raynaud's often have symptoms related to their underlying rheumatic

145

disease such as:Arthritis, Rash and thickening or hardening of the skin

Mechanism

 Nifedipine makes blood vessels relax and widen. This should help the blood flow to fingers and toes.  A summary of lots of randomised controlled trials has shown that nifedipine can help prevent Unusual uses of common drugs by Ahmed Yossef

 Nifedipine 10–30 mg 3 times daily orally  Sustained-release nifedipine 30–120 mg/day orally

3- Nifedipine for anal fissure

 An anal fissure or rectal fissure is a break or tear in the skin of the anal canal. Anal fissures may be noticed by bright red anal bleeding on toilet paper, sometimes in the toilet. If acute they may cause pain after defecation but with chronic fissures pain intensity is often less.  Anal fissures usually extend from the anal opening and are usually located posteriorly in the midline, probably because of the relatively unsupported nature and poor perfusion of the anal wall in that location. Fissure depth may be superficial or sometimes down to the underlying sphincter muscle.  The goal of treatment for anal fissures is to break the cycle of spasm of the anal sphincter and its repeated tearing of the anoderm.

Unusual uses of common drugs by Ahmed Yossef

149

Mechanism

 Nifedipine relax the muscles of the internal sphincter. They also expand the blood vessels of the anoderm and increase the flow of blood. Although healing of chronic fissures has been reported in up to 67% of patients treated with nifedipine , they are most effective with acute fissures. Dose

 Nifedipine 0.2% ointment should be used twice a day, once in the morning and once at night for 3-6 weeks.  Oral nifedipine 20mg twice daily Unusual uses of common drugs by Ahmed Yossef

4-Nifedipine (as secondary therapy) in expulsion ureteral stones

 Nifedipine has been used for facilitating the spontaneous expulsion of ureteral stones. It several studies without significant biases showed higher expulsion rates in comparison with control groups, and events of renal colic were not reduced.  The expulsion of the stones required an average time of up to 12 days. It should be noted that the majority of the studies include distal ureteral and vesicoureteral stones.

157

What (Natural Killer Cells) are??

It is immune cells in the uterus are important in the early detection and elimination of foreign cells, such as infections or cancer. Natural Killer Cells bind themselves to the diseased or infected target cells and release a potent cytotoxic chemical called tumour necrosis factor (TNF) that kills these cells. Natural Killer Cells form a normal part of our blood and play an important role in our bodies’ defence mechanism.

Women who have fertility problems, specifically miscarriage or unsuccessful IVF are more likely to have higher levels of activity of these Natural Killer cells than other women. High natural killer cell activity is a form of immunological infertility. Unusual uses of common drugs by Ahmed Yossef

 In order for successful implantation to occur, an adequately prepared endometrium has to be built up during the menstrual cycle. Endometrial development is regulated by steroid hormones and various growth factors and cytokines. Unusual uses of common drugs by Ahmed Yossef

167

 Some of these factors are produced locally and act via paracrine mechanisms; others have to be transferred to the endometrium. Sufficient uterine blood supply is required for these factors to reach the endometrium, especially to its functional layer.  Most studies agree that the endometrium has to reach a certain thickness for successful pregnancy to occur. Mechanism

 Nitric oxide relaxes vascular smooth muscle, an effect that is mediated by cyclic guanosine monophosphate (cGMP). Guanylate cyclase and cGMP have been detected in human myometrium obtained from both non pregnant and pregnant women.  Sildenafil is a selective inhibitor of the type V cGMP-specific phosphodiesterase. With the use of sildenafil, cGMP levels remain elevated, which leads to vascular relaxation and increased blood flow. Unusual uses of common drugs by Ahmed Yossef

168

 Sildenafil increase the blood flow to the uterus and to improve both the pattern and thickness of the endometrium.  Sildenafil improved pelvic blood flow can have a beneficial effect on ovarian function. Sildenafil suppositories rather than oral tablets were used in order to reduce the side effects such as headaches and low blood pressure because it deliver the drug near the proximity of the uterus.

3- Sildenafil in the treatment of pulmonary arterial hypertension in infants and adults.

 Pulmonary arterial hypertension (PAH) is a progressive, and often fatal, debilitating disorder.  The increased pulmonary artery pressure found in PAH is due to disturbances in key vascular mediator pathways including relative deficiencies of vasodilators such as nitric oxide (NO) and Unusual uses of common drugs by Ahmed Yossef

prostacyclin, as well as exaggerated production of vasoconstrictors such as endothelin and thromboxanes. Symptoms

 Progressive breathlessness, exertion limitation, frequent decline and failure of the right ventricle. Mechanism

 Sildenafil is a selective inhibitor of phosphodiesterase type 5 (PDE5). Present throughout the body, PDE5 is found in high concentrations in the lungs. Inhibition of PDE5 enhances the vasodilatory effects of nitric oxide in pulmonary hypertension by preventing the degradation of cyclic guanosine monophosphate (cGMP), which promotes relaxation of vascular smooth muscle and increases blood flow.  In animal models and human trials, sildenafil has been found to produce a relatively selective reduction in pulmonary artery pressure without Unusual uses of common drugs by Ahmed Yossef

adverse systemic hemodynamic effects after 3 months of oral therapy.  Inhibition of PDE5 by sildenafil may also enhance the platelet antiaggregatory activity of nitric oxide and inhibit thrombus formation. Infant’s dose

 A single dose of sildenafil in infants prevented rebound pulmonary hypertension and significantly reduced the duration of mechanical ventilation in intensive care unit (ICU) infants being withdrawn from inhaled nitric oxide therapy. Adult’s dose

 Oral: 5 mg or 20 mg three times a day taken at least 4 to 6 hours apart.  Injection: 2.5 mg or 10 mg administered as an intravenous bolus injection three times a day. The injection dose does not need to be adjusted for body weight. Unusual uses of common drugs by Ahmed Yossef

4- Sildenafil for Raynaud’s syndrome

 Raynaud's phenomenon is a blood vessel disorder. When healthy people are in a cold environment, the tiny blood vessels in their skin constrict, or narrow. This is an effort by the body to conserve heat. Unusual uses of common drugs by Ahmed Yossef

178

 In people with Raynaud's phenomenon, that natural response to cold is exaggerated. The tiny blood vessels go into spasm, narrowing and reducing the blood flow to the affected areas. This response, called vasospasm, is seen most often in the fingers and toes. But it also can occur in the ears, cheeks and nose.  In some people, the constriction also can occur in response to emotional stress or a rapid change of temperature from warm to cool. Or, it may occur for no apparent reason.  The effect of this vasospasm can be dramatic and frightening. But it is temporary and rarely dangerous. Once the affected area is warmed, the blood vessels relax and expand. This allows more blood flow.  People who do not have any other symptoms or disease are said to have primary Raynaud's. People who have Raynaud's as part of another disease are said to have secondary Raynaud's. Unusual uses of common drugs by Ahmed Yossef

179

 Secondary Raynaud's is commonly linked to connective-tissue disorders, such as scleroderma and lupus. It also can result from blood vessel damage due to injury, frostbite or use of jarring machinery, such as jackhammers or chainsaws. Symptoms

 People with Raynaud's see and feel changes in their fingers and toes when exposed to cold. The skin blanches, or turns white, then blue. Fingers and toes can tingle or feel numb.  When rewarmed, the skin flushes pink or red. And there can be throbbing or soreness as the blood surges back into the tiny blood vessels.  People with secondary Raynaud's often have symptoms related to their underlying rheumatic disease such as:Arthritis, Rash and thickening or hardening of the skin  Patients taking sildenafil, Raynaud's attacks were less frequent and shorter and the mean Raynaud's Condition Score was significantly lower.

1-Spironolactone in treatment of acne for women.

 Acne is triggered by an excess production of sebum. Sebum is an oil made by glands in your skin. Along with skin cells, sebum can clog pores and promote the growth of bacteria that contribute to acne. Androgens, a group of hormones that includes testosterone, stimulate your skin to produce sebum.

Unusual uses of common drugs by Ahmed Yossef

187

 A woman's ovaries and adrenal glands normally produce a low level of androgens. Higher levels of androgens can lead to excess sebum. Mechanism

 Spironolactone is an aldosterone antagonist with anti-androgenic properties.  The mechanism of action includes competition for the androgen receptor, suppression of cytochrome P450, and inhibition of steroidogenesis, as well as reduction in 5-α-reductase activity.  Spironolactone also decreases sebum production and improves acne. Dose:

 The therapeutic dose for acne therapy is 50–100 mg per day

2-Spironolactone in treatment of hirsutism for women.

 Hirsutism is a common, often distressing condition in which a person develops excessive growth of hair Causes of hirsutism

 In many cases, the exact cause of hirsutism is not known. However, there are several conditions that are known to cause hirsutism. These conditions include:  The natural production of male hormones (androgens). Women naturally produce androgen, however, if a woman's androgen levels are higher Unusual uses of common drugs by Ahmed Yossef

190

than normal, or if her hair follicles are more sensitive to androgens, she may develop hirsutism.  Polycystic ovarian syndrome (PCOS) is a common hormonal condition that causes a woman to produce too many androgens. Women with PCOS may also have acne, irregular or absent menstrual periods, diabetes, weight gain, and/or problems with fertility.  The hormonal changes of menopause may lead to increased facial hair (mustache and whiskers).  Hirsutism that occurs suddenly along with other male characteristics, such as a deeper voice, acne, or increased muscle mass, may be caused by a more serious condition, such as disorders of the adrenal glands or ovaries.  The following medications can cause hirsutism: Anabolic steroids,testosterone,glucocorticoids, minoxidil ,danazol and phenytoin .

3-Spironolactone Treat polycystic ovary syndrome (PCOS) problems

 Polycystic ovary syndrome PCOS is one of the most common endocrine disorders among females. PCOS has a diverse range of causes that are not entirely understood, but there is strong evidence that it is largely a genetic disease  The most common immediate symptoms are anovulation, excess androgenic hormones, and insulin resistance. Anovulation results in irregular menstruation, amenorrhea, and ovulationrelated infertility. Imbalance generally causes acne and hirsutism. Insulin resistance is Unusual uses of common drugs by Ahmed Yossef

associated with obesity, Type 2 diabetes, and high cholesterol levels. The symptoms and severity of the syndrome vary greatly among affected women.  Treatments for hirsutism in women with PCOS are similar to those in women without PCOS, such as patients with idiopathic hirsutism. Several medications have been studied for the treatment of hirsutism in women with PCOS. First-line agents include spironolactone and metformin Mechanism

4-Spironolactone in treatment of female pattern hair loss

Unusual uses of common drugs by Ahmed Yossef

196

 Life cycle of hair is divided into three phases  Anagen -- active hair growth that lasts between two to six years  Catagen -- transitional hair growth that lasts two to three weeks  Telogen -- resting phase that lasts about two to three months; at the end of the resting phase the hair is shed and a new hair replaces it and the growing cycle starts again.  As people age, their rate of hair growth slows  Almost every woman eventually develops some degree of female pattern hair loss. It can start any time after the onset of puberty, but women tend to first notice it around menopause, when hair loss typically increases. The risk rises with age, and it's higher for women with a history of hair loss on either side of the family.  As the name suggests, androgenetic alopecia involves the action of the hormones called androgens, which are essential for normal male sexual development and have other important Unusual uses of common drugs by Ahmed Yossef

197

functions in both sexes, including sex drive and regulation of hair growth.  The condition may be inherited and involve several different genes. It can also result from an underlying endocrine condition, such as overproduction of androgen or an androgensecreting tumor on the ovary, pituitary, or adrenal gland. In either case, the alopecia is likely related to increased androgen activity.  But unlike androgenetic alopecia in men, in women the precise role of androgens is harder to determine. On the chance that an androgen-secreting tumor is involved, it's important to measure androgen levels in women with clear female pattern hair loss.  In either sex, hair loss from androgenetic alopecia occurs because of a genetically determined shortening of anagen, a hair's growing phase, and a lengthening of the time between the shedding of a hair and the start of a new anagen phase. That means it takes longer for hair to start growing back Unusual uses of common drugs by Ahmed Yossef

198

after it is shed in the course of the normal growth cycle.  The hair follicle itself also changes, shrinking and producing a shorter, thinner hair shaft — a process called "follicular miniaturization." As a result, thicker, pigmented, longer-lived "terminal" hairs are replaced by shorter, thinner, non-pigmented hairs called "vellus." Mechanism

 Spironolactone is an antiandrogen that works in two ways. Primarily it slows down the production of androgens in the adrenal glands and ovaries. Secondly it blocks the action of androgens in part by preventing dihydrotestosterone from binding to its androgenetic receptor. Dose:

 100 to 200 milligrams daily

Mechanism:-

It is a prodrug, that is, it is not active in its ingested form. It is broken down by bacteria in the colon into 5-aminosalicylic acid (5ASA), and sulfapyridine. 5-aminosalicylic acid (5-ASA) may reduce inflammation by blocking the activity of cyclooxygenase thereby reducing the production of prostaglandins and relief rheumatoid arthritis pain. references :http://www.medicinenet.com/sulfasalazine/article.htm http://www.webmd.com/drugs/2/drug-6260/sulfasalazine-oral/details http://www.mayoclinic.org/drugs-supplements/sulfasalazine-oral-route/description/drg-20066179 http://www.nlm.nih.gov/medlineplus/druginfo/meds/a682204.html

2- Topiramate AND phentermine as an addition to a reduced-calorie diet and exercise for chronic weight management. (FDA APPROVED USE)

 Qsymia is a combination of two FDA-approved drugs, phentermine and topiramate, in an extendedrelease formulation. MECHANISM

 Phentermine is a sympathomimetic agent that has been used by itself for the treatment of obesity for quite some time.  Although the exact mechanism by which phentermine works to promote weight loss is not understood, it is thought to stimulate the release of chemicals from the hypothalamus, the area of the brain known to have a major role in regulating hunger and food intake.  Phentermine induced release of chemicals is thought to reduce appetite and decrease food intake, among other effects.

 Topiramate, the other medicine in Qsymia, is an anti-seizure medication that has been observed to be effective in causing weight loss. The precise mechanism by which topiramate works to stimulate weight loss is not yet understood. However, similar to the actions of phentermine, topiramate is also thought to suppress appetite and make a person feel full even after eating less food than usual.

DOSE The recommended daily dose of Qsymia contains 7.5 milligrams of phentermine and 46 mg of topiramate extendedrelease. Qsymia is also available at a higher dose (15 mg phentermine and 92 mg of topiramate extended-release) for select patients.

Trimethoprim-Sulfamethoxazole in treatment of acne vulgaris

.

Mechanism:

many bacteria are not capable of incorporating exogenous folate, they are dependent on their own ability to synthesize folate that is needed for their own protein and deoxyribonucleic acid (DNA) production. TMP-SMZ inhibits folate production in bacteria by blocking bacterial dihydrofolic acid reductase, which causes reduced production of purines and subsequently DNA.

Notes

1- this combination uses in Severe Acne. 2-it is less often used for acne BUT when other antibiotics have failed, especially when isotretinoin is not an option. 3-Some dermatologists claim that the response to trimethoprim-sulfamethoxazole is as impressive as the response to isotretinoin. However, unlike isotretinoin, the effect of trimethoprim-sulfamethoxazole is not sustained after it is stopped. Dose

1 DS tab or 1 regular-strength tab orally every Day or every 12hr for up to 18 weeks. . .
