DrugDrug NameDrug Description
DB01395DrospirenoneDrospirenone is a synthetic progestin commonly found in the popular oral contraceptive, Yaz in combination with [Ethinyl estradiol].[L7973] Aside from its contraceptive effects, drospirenone is used with estrogens to control acne and premenstrual dysphoric disorder (PMDD). Drospirenone has been the subject of widespread safety concern due to the possibility of an increased risk of venous thromboembolism associated with its use.[A182543,A182552] In 2012, however, a safety statement by the FDA concluded that the increase in the risk of thromboembolism resulting from the use of drospirenone remains unclear, as studies regarding this risk are conflicting. Some studies have demonstrated a significantly increased risk and some demonstrating no risk of thromboembolic events. In its statement, the FDA has mentioned that increased risk of venous thromboembolism with oral contraceptives such as drospirenone exists but remains lower than the risk of this condition during pregnancy and during the postpartum period, and this should be considered when assessing potential risks of hormonal contraceptive use.[L7979]
DB00977EthinylestradiolA semisynthetic alkylated estradiol with a 17-alpha-ethinyl substitution. It has high estrogenic potency when administered orally and is often used as the estrogenic component in oral contraceptives. Ethinyl estradiol is marketed mostly as a combination oral contraceptive under several brand names such as Alesse, Tri-Cyclen, Triphasil, and Yasmin. The FDA label includes a black box warning that states that combination oral contraceptives should not be used in women over 35 years old who smoke due to the increased risk of serious cardiovascular side effects.
DB00823Ethynodiol diacetateA synthetic progestational hormone used alone or in combination with estrogens as an oral contraceptive. Although etynodiol or ethynodiol are sometimes used as a synonym for ethynodiol diacetate, what is usually being referred to is actually ethynodiol diacetate and not ethynodiol (which is a separate drug that has never been marketed, see [DB13866]).
DB01216FinasterideFinasteride is a synthetic 4-azasteroid compound[Label] and specific inhibitor of steroid Type II 5α-reductase, which is an intracellular enzyme that converts the androgen testosterone into 5α-dihydrotestosterone (DHT). It works in a similar fashion as [dutasteride], which is another 5-alpha-reductase inhibitor, by exerting antiandrogenic effects. Finasteride is an orally active drug that was first approved by the FDA in 1992 for the treatment of benign prostatic hyperplasia to improve symptoms and reduce the risk for acute urinary retention or the need for surgical procedures.[Label,L6244] In 1998, it was approved by the FDA to treat male pattern hair loss.[L6244] Finasteride is commonly marketed under the brand names Propecia and Proscar to be used aloneo or in combination with [doxazosin], an alpha-blocker. Both benign prostatic hyperplasia and androgenic alopecia are androgen-dependent disorders that are characterized by _in situ_ high levels of DHT.[A178159] In the treatment of benign prostate hyperplasia, alpha-blockers such as [tamsulosin] and [terazosin] are also used. Compared to alpha-blockers that focus on providing the rapid relief of symptoms, 5α-reductase inhibitors aim to target the underlying disease by blocking the effects of the primary androgen involved in benign prostate hyperplasia and androgenic alopecia, thus reducing the risk for secondary complications while providing symptom control.[A2132]
DB01006LetrozoleLetrozole (INN, trade name Femara®) is an oral non-steroidal aromatase inhibitor that has been introduced for the adjuvant treatment of hormonally-responsive breast cancer Estrogens are produced by the conversion of androgens through the activity of the aromatase enzyme. Letrozole blocks the production of estrogens in this way by competitive, reversible binding to the heme of its cytochrome P450 unit. It is important to note that letrozole does not decrease the production of mineralocorticoids or corticosteroids. In contrast, the antiestrogenic action of tamoxifen, the major medical therapy prior to the arrival of aromatase inhibitors, is due to its interfering with the estrogen receptor, rather than inhibiting estrogen production. Side effects include signs and symptoms of hypoestrogenism. There is concern that long term use may lead to osteoporosis, which is why prescriptions of Letrozole are often accompanied by prescriptions of osteoporosis-fighting medication such as Fosamax. Letrozole has shown to reduce estrogen levels by 98 percent while raising testosterone levels. The anti-estrogen action of letrozole is preferred by athletes and bodybuilders for use during a steroid cycle to reduce bloating due to excess water retention and prevent the formation of gynecomastia related breast tissue that is a side effect of some anabolic steroids. Usage above 2.5 mg/day is known to potentially temporarily kill sex drive. Above 5mg/day for extended periods may cause kidney problems. Letrozole has also been shown to delay the fusing of the growth plates in adolescents. This may boost the effectiveness of growth hormone, and thus Letrozole is used to treat adolescents and children with short stature.
DB01357MestranolThe 3-methyl ether of ethinyl estradiol. It must be demethylated to be biologically active. It is used as the estrogen component of many combination ORAL contraceptives.
DB06713NorelgestrominNorelgestromin is a drug used in contraception. Norelgestromin is the active progestin responsible for the progestational activity that occurs in women after application of ORTHO EVRA patch.
DB00957NorgestimateNorgestimate is a form of progesterone, which is a female hormone important for the regulation of ovulation and menstruation. Norgestimate is used with estradiol to treat the symptoms of menopause.
DB09389NorgestrelNorgestrel is synthetic steroidal progestin that is used in combination with ethinyl estradiol for oral contraception. Norgestrel is composed of a racemic mixture of two stereoisomers, dextronorgestrel and levonorgestrel. However, only the levorotary enantiomer ([levonorgestrel]) is biologically active.
