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.

SERMs bind to estrogen receptors and act like estrogen in some tissues (bone, vagina) while blocking estrogen in others (breast, uterus). This tissue-selective action can treat menopause symptoms without systemic estrogen.
