Drospirenone is a synthetic progestogen that binds to the progesterone, mineralocorticoid, and androgen receptors with binding affinities of 20, 230, and 65% relative to R5020, aldosterone (Cay-15273), and R1881, respectively. In vivo, drospirenone inhibits spontaneous ovulation in rats (ID50s = 0.3-1.0 mg/day) when administered orally or subcutaneously. Drospirenone (0.5 mg/animal) administered six times per day maintains pregnancy in ovariectomized pregnant rats. It reduces serum testosterone (Cay-15645, Cay-ISO60154) and luteinizing hormone in cynomolgus monkeys in a dose-dependent manner. Drospirenone (10 mg/animal per day) also inhibits testosterone-induced growth of the seminal vesicles and prostate in castrated rats. Formulations containing drospirenone have been used as oral contraceptives.Formal Name: 1,3',4',6R,7R,8R,9S,10R,11,12,13S,14S,15S,16S,20,21-hexadecahydro-10,13-dimethyl-spiro[17H-dicyclopropa[6,7:15,16]cyclopenta[a]phenanthrene-17,2'S(5'H)-furan]-3,5'(2H)-dione.
