Estrone is a naturally occurring estrogenic hormone and a member of the estrogen class of hormones. Used primarily in hormone replacement therapy for menopausal symptoms, it is rarely used today as other estrogens such as estradiol are preferred. Estrone may also be found as part of combination hormone preparations.
Pharmacokinetics
Estimated pharmacokinetic parameters for adult women; no direct published source available. Parameter values extrapolated from known estrone pharmacokinetic properties as reported in reviews and pharmacology reference texts.
