Hydroxyprogesterone heptanoate (OHPH), sold under the brand names H.O.P., Lutogil A.P., and Lutogyl A.P. among others, is a progestin medication which was developed by Roussel and Théramex and has been used clinically in France and Monaco but is no longer marketed.[1][2][3][4] It was a component of the experimental preparation Trophoboline (or Trophobolene), which also contained nandrolone decanoate and estrapronicate.[5][6][7] The medication was also studied or used in Tocogestan, a combination of hydroxyprogesterone heptanoate (200 mg), progesterone (50 mg), and tocopherol (250 mg) oil for intramuscular injection.[8][4][9] OHPH has been marketed since at least 1957, in combination preparations such as Triormon Depositum (estradiol dibutyrate, testosterone caproate, and OHPH) and Trioestrine Retard (estradiol diundecylate, testosterone cyclohexylpropionate, and OHPH).[10][11]


OHPH, also known as hydroxyprogesterone enanthate (OHPE),[12] as well as 17α-hydroxyprogesterone heptanoate or 17α-hydroxypregn-4-ene-3,20-dione 17α-heptanoate, is a synthetic pregnane steroid and a derivative of progesterone and 17α-hydroxyprogesterone.[1][2] It is a progestogen ester; specifically, it is the C17α heptanoate (enanthate) ester of 17α-hydroxyprogesterone.[1][2] Analogues of OHPH include hydroxyprogesterone acetate and hydroxyprogesterone caproate.[1][2]

Quaderni clin. ostet. e ginecol. 12: 284–93. Triormon depositum (estradiol dibutyrate 3, testosterone caprylate 50, and hydroxyprogesterone heptanoate 30 mg.), administered in castor oil-benzyl benzoate soln. or polyvinylpyrrolidone suspension to 21 women in climacteric, was followed by estradiol, pregnanediol, and 17-keto steroid urinary curves, most with a peak at the 4th day, and approaching starting values at the 8-10th day. The therapeutic efficacy of the drug was satisfactory.

The patients (females) received intramuscularly, every 10 days for 2-3 months, estradiol diundecyleate 2.25, testosterone cyclohexylpropionate 67.5, and hydroxyprogesterone heptylate 100 mg. ("trioestrine retard"). Their av. calcuria decreased 30.5% (0-69%) and asthenia, anorexia, and muscular activity improved.
