Estradiol stearate (brand name Depofollan), or estradiol octadecanoate, is a naturally occurring steroidal estrogen and an estrogen ester – specifically, the C17β stearate ester of estradiol.[1][2][3] It occurs in the body as a very long-lasting metabolite and prohormone of estradiol.[3] In addition, estradiol stearate is or has been available as a pharmaceutical drug for use via depot intramuscular injection.[1][2] The drug was introduced in 1941 as Depofollan and was the first long-acting estrogen, although it has never been widely used.[4] It has been reported in at least one source to have a duration of at least one month.[4]
