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.

Excess body fat may contribute to vasomotor symptoms by altering thermoregulation and hormone metabolism. Losing weight through behavioral changes (diet and exercise) may reduce the frequency and severity of hot flashes, particularly for women who are overweight or obese and earlier in the menopause transition.
