List of antiandrogens

This is a list of antiandrogens,[1] or drugs that prevent the effects of androgens like testosterone and dihydrotestosterone (DHT).[2] It includes direct antagonists of the androgen receptor (AR), androgen synthesis inhibitors like 5α-reductase inhibitors and CYP17A1 inhibitors, and antigonadotropins like GnRH analogues, estrogens, and progestogens.[3] In addition, it includes both steroidal antiandrogen (SAAs) and nonsteroidal antiandrogen (NSAAs). Only antiandrogens that have been marketed are included in this list.[4]

Testosterone, the major endogenous androgen and the target mediator of antiandrogens.

Androgen receptor antagonists

Cyproterone acetate, the most widely used steroidal antiandrogen.

Note that in addition to acting as AR antagonists, most SAAs also act as potent progestogens and therefore antigonadotropins.

Note that this list does not include pure progestogens, only SAAs also acting as AR antagonists.

Bicalutamide, the most widely used nonsteroidal antiandrogen.

Note that, in contrast to most SAAs, NSAAs are pure/selective AR antagonists with no antigonadotropic activity.

Abiraterone acetate, a CYP17A1 inhibitor and by extension an androgen synthesis inhibitor.

Dutasteride, a 5α-reductase inhibitor and by extension a DHT synthesis inhibitor.

These drugs selectively inhibit the synthesis of DHT without affecting that of testosterone.
