Estradiol pivalate/progesterone

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]
