Ospemifene

Ospemifene (commercial name Osphena produced by Shionogi) is an oral medication indicated for the treatment of dyspareunia –pain during sexual intercourse –encountered by some women, more often in those who are post-menopausal. Ospemifene is a selective estrogen receptor modulator (SERM) acting similarly to an estrogen on the vaginal epithelium, building vaginal wall thickness which in turn reduces the pain associated with dyspareunia. Dyspareunia is most commonly caused by "vulval and vaginal atrophy."
