How it works

Blocks neurokinin-3 (NK3) and/or neurokinin-1 (NK1) receptors in the hypothalamus to interrupt the temperature-regulation pathway that triggers hot flashes and night sweats.

Bioadhesive polymers (such as polycarbophil or hyaluronic acid) bind to vaginal tissue and retain water, hydrating and lubricating the vaginal mucosa. They lower vaginal pH toward premenopausal levels and are applied every 2 to 3 days, independent of sexual activity.
