Danazol
Danazol, sold as Danocrine and other brand names, is a medication used in the treatment of endometriosis, fibrocystic breast disease, hereditary angioedema and other conditions. It is taken by mouth. The use of danazol is limited by masculinizing side effects such as acne, excessive hair growth, and voice deepening. Danazol has a complex mechanism of action, and is characterized as a weak androgen and anabolic steroid, a weak progestogen, a weak antigonadotropin, a weak steroidogenesis inhibitor, and a functional antiestrogen. Danazol was discovered in 1963 and was introduced for medical use in 1971. Due to their improved side-effect profiles, particularly their lack of masculinizing side effects, danazol has largely been replaced by gonadotropin-releasing hormone analogues (GnRH analogues) in the treatment of endometriosis. Medical uses Danazol is used primarily in the treatment of endometriosis. It has also been used – mostly off-label – for other indications, name ...

Steroidogenesis Inhibitor
A steroidogenesis inhibitor, also known as a steroid biosynthesis inhibitor, is a type of drug which inhibits one or more of the enzymes that are involved in the process of steroidogenesis, the biosynthesis of endogenous steroids and steroid hormones. They may inhibit the production of cholesterol and other sterols, sex steroids such as androgens, estrogens, and progestogens, corticosteroids such as glucocorticoids and mineralocorticoids, and neurosteroids. They are used in the treatment of a variety of medical conditions that depend on endogenous steroids. Steroidogenesis inhibitors are analogous in effect and use to antigonadotropins (which specifically inhibit gonadal sex steroid production), but work via a different mechanism of action; whereas antigonadotropins suppress gonadal production of sex steroids by effecting negative feedback on and thereby suppressing the hypothalamic–pituitary–gonadal axis, steroidogenesis inhibitors directly inhibit the enzymatic biosynth ...

Anabolic Steroid
Anabolic steroids, also known more properly as anabolic–androgenic steroids (AAS), are steroidal androgens that include natural androgens like testosterone as well as synthetic androgens that are structurally related and have similar effects to testosterone. They increase protein within cells, especially in skeletal muscles, and also have varying degrees of virilizing effects, including induction of the development and maintenance of masculine secondary sexual characteristics such as the growth of facial hair, facial and body hair. The word ''anabolic'', referring to anabolism, comes from the Greek ἀναβολή ''anabole'', "that which is thrown up, mound". Androgens or AAS are one of three types of sex hormone agonists, the others being estrogen (medication), estrogens like estradiol (medication), estradiol and progestogens like progesterone (medication), progesterone. AAS were synthesized in the 1930s, and are now used therapeutically in medicine to stimulate muscle g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endometriosis
Endometriosis is a disease of the female reproductive system in which cells similar to those in the endometrium, the layer of tissue that normally covers the inside of the uterus, grow outside the uterus. Most often this is on the ovaries, fallopian tubes, and tissue around the uterus and ovaries; in rare cases it may also occur in other parts of the body. Some symptoms include pelvic pain, heavy periods, pain with bowel movements, and infertility. Nearly half of those affected have chronic pelvic pain, while in 70% pain occurs during menstruation. Pain during sexual intercourse is also common. Infertility occurs in up to half of affected individuals. About 25% of individuals have no symptoms and 85% of those seen with infertility in a tertiary center have no pain. Endometriosis can have both social and psychological effects. The cause is not entirely clear. Risk factors include having a family history of the condition. The areas of endometriosis bleed each month (menstr ...

Antigonadotropin
An antigonadotropin is a drug which suppresses the activity and/or downstream effects of one or both of the gonadotropins, follicle-stimulating hormone (FSH) and luteinizing hormone (LH). This results in an inhibition of the hypothalamic-pituitary-gonadal (HPG) axis, and thus a decrease in the levels of the androgen, estrogen, and progestogen sex steroids in the body. Antigonadotropins also inhibit ovulation in women and spermatogenesis in men. They are used for a variety of purposes, including for the hormonal birth control, treatment of hormonally-sensitive cancers, to delay precocious puberty and puberty in transgender youth, as a form of chemical castration to reduce the sex drives of individuals with hypersexuality or pedophilia, and to treat estrogen-associated conditions in women such as menorrhagia and endometriosis, among others. High-dose antigonadotropin therapy has been referred to as ''medical castration''. The best-known and widely used antigonadotropins ar ...

Progestogen (medication)
A progestogen, also referred to as a progestagen, gestagen, or gestogen, is a type of medication which produces effects similar to those of the natural female sex hormone progesterone in the body. A progestin is a ''synthetic'' progestogen. Progestogens are used most commonly in hormonal birth control and menopausal hormone therapy. They can also be used in the treatment of gynecological conditions, to support fertility and pregnancy, to lower sex hormone levels for various purposes, and for other indications. Progestogens are used alone or in combination with estrogens. They are available in a wide variety of formulations and for use by many different routes of administration. Examples of progestogens include natural or bioidentical progesterone as well as progestins such as medroxyprogesterone acetate and norethisterone. Side effects of progestogens include menstrual irregularities, headaches, nausea, breast tenderness, mood changes, acne, increased hair growth, and c ...

Ethisterone
Ethisterone, also known as ethinyltestosterone, pregneninolone, and anhydrohydroxyprogesterone and formerly sold under the brand names Proluton C and Pranone among others, is a progestin medication which was used in the treatment of gynecological disorders but is now no longer available. It was used alone and was not formulated in combination with an estrogen (medication), estrogen. The medication is taken oral administration, by mouth. Side effects of ethisterone include virilization, masculinization among others. Ethisterone is a progestin, or a synthetic compound, synthetic progestogen (medication), progestogen, and hence is an agonist of the progesterone receptor, the biological target of progestogens like progesterone. It has some androgenic and anabolic activity and no other important hormonal agent, hormonal activity. Ethisterone was discovered in 1938 and was introduced for medical use in Germany in 1939 and in the United States in 1945. It was the second progestogen ( ...

Hereditary Angioedema
Hereditary angioedema (HAE) is a disorder that results in recurrent attacks of severe swelling. The swelling most commonly affects the arms, legs, face, intestinal tract, and airway. If the intestinal tract is affected, abdominal pain and vomiting may occur. Swelling of the airway can result in its obstruction and trouble breathing. Without preventive treatment, attacks typically occur every two weeks and last for a few days. There are three main types of HAE. Types I and II are caused by a mutation in the '' SERPING1'' gene, which makes the C1 inhibitor protein, while type III is often due to a mutation in the '' F12'' (factor XII) gene. The result is increased levels of bradykinin, which promotes swelling. The condition may be inherited in an autosomal dominant manner or occur as a new mutation. Triggers for an attack may include minor trauma or stress, but attacks often occur without any obvious preceding event. Diagnosis of types I and II is based on measurement of C4 and C ...
