Algestone acetophenide, also known as dihydroxyprogesterone acetophenide, is an agonist of the progesterone receptor. Algestone acetophenide in combination with estradiol enanthate is sold under the brand name Deladroxate as a form of long-lasting injectable birth control. The combination provides simultaneously prolonged progestational and estrogenic activities both of which are maintained at effective levels for approximately three weeks after the intramuscular injection of a single dose.
