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 oral administration, by mouth. The use of danazol is limited by virilization, masculinizing side effects such as acne, hirsutism, 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 (medication), 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Due to their improved side-effect profiles, particularly their lack of masculinizing side effects, danazol has largely been replaced by gonadotropin-releasing hormone analogues (GnRH analogues) in the treatment of endometriosis.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 ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endometriosis
Endometriosis is a disease in which Tissue (biology), tissue similar to the endometrium, the lining of the uterus, grows in other places in the body, outside the uterus. It occurs in women and a limited number of other female mammals. Endometrial tissue most often grows on or around reproductive organs such as the ovaries and fallopian tubes, on the outside surface of the uterus, or the tissues surrounding the uterus and the ovaries (peritoneum). It can also grow on other organs in the pelvic region like the Gastrointestinal tract, bowels, stomach, bladder, or the cervix. Rarely, it can also occur in other parts of the body. Symptoms can be very different from person to person, varying in range and intensity. About 25% of individuals have no symptoms, while for some it can be a debilitating disease. Common symptoms include pelvic pain, Heavy menstrual bleeding, heavy and Dysmenorrhea, painful periods, pain with bowel movements, Dysuria, painful urination, Dyspareunia, pain dur ...

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 biosy ...

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 encodes the C1 inhibitor protein, and type III now called HAE with Normal C1 esterase(HAE nl C1). Six known mutations are described in the literature under the type 3 HAE. 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 even ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fibrocystic Breast Disease
Fibrocystic breast changes is a condition of the breasts where there may be pain, breast cysts, and breast masses. The breasts may be described as "lumpy" or "doughy". Symptoms may worsen during certain parts of the menstrual cycle due to hormonal stimulation. These are normal breast changes, not associated with cancer. Risk factors include an early age at first menstrual period and either having children at a late age or not at all. It is not a disease but represents normal breast changes. Diagnosis involves ruling out breast cancer. Fibrocystic changes include fibroadenomas, fibrosis, papillomas of the breast, and apocrine-type metaplasia. Management may involve education about the condition, using a well fitting bra, and pain medication, if needed. Occasionally danazol or tamoxifen may be used for pain. It is estimated that up to 60% of women are affected, most commonly between the ages of 30 and 50 years. Signs and symptoms The changes in fibrocystic breast disease are c ...

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 ...

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 are the g ...

Antiestrogen
Antiestrogens, also known as estrogen antagonists or estrogen blockers, are a class of drugs which prevent estrogens like estradiol from mediating their biological effects in the body. They act by blocking the estrogen receptor (ER) and/or inhibiting or suppressing estrogen production., Antiestrogens are one of three types of sex hormone antagonists, the others being antiandrogens and antiprogestogens. Antiestrogens are commonly used to stop steroid hormones, estrogen, from binding to the estrogen receptors leading to the decrease of estrogen levels. Decreased levels of estrogen can lead to complications in sexual development. Types and examples Antiestrogens include selective estrogen receptor modulators (SERMs) like tamoxifen, clomifene, and raloxifene, the ER silent antagonist and selective estrogen receptor degrader (SERD) fulvestrant, aromatase inhibitors (AIs) like anastrozole, and antigonadotropins including androgens/anabolic steroids, progestogens, and GnRH an ...
