Hydroxyprogesterone heptanoate (OHPH), also known as hydroxyprogesterone enanthate (OHPE) and sold under the brand names H.O.P., Lutogil A.P., and Lutogyl A.P. among others, is a progestin medication used for progestogenic indications.[1][2][3][4] It has been formulated both alone and in together with estrogens, androgens/anabolic steroids, and other progestogens in several combination preparations (brand names Tocogestan, Trioestrine Retard, and Triormon Depositum).[4][5][6][7][8][9][10] OHPH is given by injection into muscle at regular intervals.[11][9]
OHPH is a progestin, or a synthetic progestogen, and hence is an agonist of the progesterone receptor, the biological target of progestogens like progesterone.[12][13][14] It appears to have similar pharmacology to that of the closely related medication hydroxyprogesterone caproate (OHPC).[15][16][17]
OHPH was first described by 1954[16] and was introduced for medical use by 1957.[6] It has been used clinically in France and Monaco in the past but is no longer marketed.[2][3][4]
