Hydroxyprogesterone heptanoate
Résumé
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. 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). OHPH is given by injection into muscle at regular intervals.
OHPH is a progestin, or a synthetic progestogen, and hence is an agonist of the progesterone receptor, the biological target of progestogens like progesterone. It appears to have similar pharmacology to that of the closely related medication hydroxyprogesterone caproate (OHPC).
OHPH was first described by 1954 and was introduced for medical use by 1957. It has been used clinically in France and Monaco in the past but is no longer marketed.
OHPH is a progestogen and was used in situations in which progestogens were indicated.
OHPH was provided as a 125 mg/1 mL oil solution for use by intramuscular injection. In addition to single-drug preparations, OHPH has also been used in a number of multi-drug formulations. It was used in Tocogestan, a combination of 50 mg progesterone, 200 mg OHPH, and 250 mg α-tocopherol palmitate (vitamin E) in oil solution for use by intramuscular injection. It was also used in Triormon Depositum (estradiol dibutyrate, testosterone caproate, and OHPH) and Trioestrine Retard (estradiol diundecylate, testosterone cyclohexylpropionate, and OHPH). OHPH was a component of the experimental preparation Trophobolene (or Trophoboline), which also contained estrapronicate (estradiol nicotinate propionate) and nandrolone undecanoate, as well.
OHPH is a progestin, or a synthetic progestogen, and hence is an agonist of the progesterone receptor, the biological target of progestogens like progesterone. The progestogenic potency of OHPH in the uterus is equal to or greater than that of progesterone when administered by subcutaneous injection in animals.
