Estradiol pivalate/progesterone (ETMA/P4), sold under the brand name Estrotate with Progesterone, is a combination medication of estradiol pivalate (estradiol trimethylacetate; ETMA), an estrogen, and progesterone (P4), a progestogen, which was used in menopausal hormone therapy and the treatment of gynecological disorders but is no longer available. [1] [2] [3] It contained 1 mg/mL ETMA and 10 mg/mL P4 in oil solution provided in vials and was administered by intramuscular injection at regular intervals. [1] [2] [3]
ETMA/P4 was introduced for medical use by 1949. [1] [2] [3] It was one of the first combined estrogen and progestogen medications to be marketed, and was followed by the more well-known estradiol benzoate/progesterone (brand name Duogynon) in 1950. [4] Other similar estrogen–progestogen preparations were also subsequently introduced. [4]

Zur kombinierten Anwendung von Gestagen en und Östrogenen stand en zunächst ölgelöstes Östradiolbenzoat und Progesteron zur Verfügung. Das erste derartige Mischpräparat kam in Deutschland 1950 auf den Mark t. Dem Wunsch nach verlän gerter Wirkungsdauer entsprach en dann Kristallmischsuspension en verschiedener Korngröße aus Östradiolmonobenzoat + Progesteron, deren Anwendung sich auf klinische Untersuchungen besch ränkte (83). Ölgelöste Depotpräparate mit Östradiolbenzoat oder -valerat + 17-hydroxyprogesteroncaproat wurden ab 1955 in die Therapie eingeführt (45.46).
