Estrone sulfate (E1S) is an estrogen medication and naturally occurring steroid hormone.[1] It is used in menopausal hormone therapy among other indications.[1][2] As the sodium salt (sodium estrone sulfate), it is the major estrogen component of conjugated estrogens (Premarin) and esterified estrogens (Estratab, Menest).[1][3] In addition, E1S is used on its own as the piperazine salt estropipate (piperazine estrone sulfate; Ogen).[1][3] The compound also occurs as a major and important metabolite of estradiol and estrone.[1] E1S is most commonly taken by mouth, but in the form of Premarin can also be taken by parenteral routes such as transdermal, vaginal, and injection.[1][2]
