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.
[1] 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.
[1][2] They are used in the treatment of a variety of medical conditions that depend on endogenous steroids.
[1] 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 biosynthesis of steroids.
