Estradiol hemihydrateProduct ingredient for Estradiol

Name
Estradiol hemihydrate
Drug Entry
Estradiol

Estradiol is a naturally occurring hormone circulating endogenously in females. It is commercially available in several hormone therapy products for managing conditions associated with reduced estrogen, such as vulvovaginal atrophy and hot flashes. Some available forms of estradiol include oral tablets, injections, vaginal rings, transdermal patches, sprays, gels, and creams.27,28,29,30,31,32,33

When used for oral or IM administration, estradiol is commonly synthesized as a pro-drug ester (such as Estradiol acetate, Estradiol benzoate, Estradiol cypionate, Estradiol dienanthate, and Estradiol valerate). Because it has a low oral bioavailability on its own, estradiol is commonly formulated with an ester side-chain. Ethinylestradiol (EE) is a synthetic form of estradiol commonly used as the estrogenic component of most combination oral contraceptive pills (OCPs). Ethinyl estradiol is different from estradiol due to its higher biovailability and increased resistance to metabolism, rendering it more suitable for oral administration.
