Oxendolone (INN, USAN, JAN) (brand name Prostetin; former developmental code name TSAA-291), also known as 16β-ethyl-17β-hydroxy-4-estren-3-one, is a steroidal antiandrogen and progestin that has been marketed in Japan by Takeda for the treatment of benign prostatic hyperplasia (BPH) since 1981.[1][2][3][4] It binds to the androgen receptor (AR) (Ki = 320 nM) and progesterone receptor (Ki = 20 nM) and acts as a weak but clinically relevant inhibitor of 5α-reductase (IC50 = 1.4 μM).[5][6][7][8] The binding affinity of oxendolone for the AR is far lower than that of cyproterone acetate.[9] At the AR, oxendolone is not a silent antagonist but is rather predominantly antagonistic with weak agonistic activity;[6] for this reason, it has been described as a selective androgen receptor modulator.[10] The drug has antigonadotropic properties via its progestogenic actions.[11] Although oxendolone is approved for the treatment of BPH in Japan, concerns have been raised about its use for this condition due to poor efficacy seen in clinical trials.[4]
