Active ingredients in G03XC

Active Ingredient

Ospemifene and its major metabolite have an oestrogen like effect in the vagina increasing the cellular maturation and mucification of the vaginal epithelium. Ospemifene’s biological actions are mediated through the binding of ospemifene and its major metabolite to oestrogen receptors leading to activation of some oestrogenic pathways (agonism) and blockade of other (antagonism).

As a selective oestrogen receptor modulator (SERM), raloxifene has selective agonist or antagonist activities on tissues responsive to oestrogen. It acts as an agonist on bone and partially on cholesterol metabolism (decrease in total and LDL-cholesterol), but not in the hypothalamus or in the uterine or breast tissues.
