An abortifacient ("that which will cause a miscarriage" from Latin: abortus "miscarriage" and faciens "making") is a substance that induces abortion.
Aglepristone (brand name Alizine; former developmental code names RU-46534, RU-534) is a synthetic, steroidal antiprogestogen related to mifepristone which is marketed by Virbac in several European countries for use in veterinary medicine.
Antiandrogens, also known as androgen antagonists or testosterone blockers, are a class of drugs that prevent androgens like testosterone and dihydrotestosterone (DHT) from mediating their biological effects in the body.
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.
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).
Biosynthesis (also called anabolism) is a multi-step, enzyme-catalyzed process where substrates are converted into more complex products in living organisms.
Breast cancer is cancer that develops from breast tissue.
A drug is any substance (other than food that provides nutritional support) that, when inhaled, injected, smoked, consumed, absorbed via a patch on the skin, or dissolved under the tongue causes a temporary physiological (and often psychological) change in the body.
Emergency contraception (EC), or emergency postcoital contraception, are birth control measures that may be used after sexual intercourse to prevent pregnancy.
In biology, function has been defined in many ways.
Gemeprost (16, 16-dimethyl-trans-delta2 PGE1 methyl ester) is an analogue of prostaglandin E1.
Lilopristone (INN) (developmental code names ZK-98734, ZK-734) is a synthetic, steroidal antiprogestogen with additional antiglucocorticoid activity which was developed by Schering and was patented in 1985.
A medical abortion is a type of non-surgical abortion in which medication is used to bring about abortion.
Mifepristone, also known as RU-486, is a medication typically used in combination with misoprostol, to bring about an abortion.
Onapristone (INN) (developmental code names ZK-89299, ZK-299) is a synthetic, steroidal antiprogestogen with additional antiglucocorticoid activity which was developed by Schering and described in 1984 but was never marketed.
In pharmacology, partial agonists are drugs that bind to and activate a given receptor, but have only partial efficacy at the receptor relative to a full agonist.
Progesterone (P4) is an endogenous steroid and progestogen sex hormone involved in the menstrual cycle, pregnancy, and embryogenesis of humans and other species.
The progesterone receptor (PR), also known as NR3C3 or nuclear receptor subfamily 3, group C, member 3, is a protein found inside cells.
Progestogens, also sometimes spelled progestagens or gestagens, are a class of steroid hormones that bind to and activate the progesterone receptor (PR).
The prostaglandins (PG) are a group of physiologically active lipid compounds having diverse hormone-like effects in animals.
A receptor antagonist is a type of receptor ligand or drug that blocks or dampens a biological response by binding to and blocking a receptor rather than activating it like an agonist.
A selective progesterone receptor modulator (SPRM) is an agent that acts on the progesterone receptor.
A sex-hormonal agent, also known as a sex-hormone receptor modulator, is a type of hormonal agent which specifically modulates the effects of sex hormones and of their biological targets, the sex hormone receptors.
A steroid is a biologically active organic compound with four rings arranged in a specific molecular configuration.
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.
Ulipristal acetate, sold under the brand name Ella among others, is a medication used for emergency birth control and uterine fibroids.
Uterine fibroids, also known as uterine leiomyomas or fibroids, are benign smooth muscle tumors of the uterus.
