Promestriene is a synthetic diethyl-ether of estradiol and a locally effective estrogen. Promestriene has an efficient action on vaginal atrophy while it is minimally absorbed[1][2].

In Vitro

Promestriene is an analogue of oestradiol which is minimally absorbed and devoid of systemic effects when administered intravaginally, either as gynecological cream or capsules[2].
Topical Promestriene is minimally absorbed with chronic use and has been reported to significantly improve the symptoms of vaginal atrophy[3].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
