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.

The exact mechanism is not fully understood. Studies suggest it may affect neurochemical pathways involved in temperature regulation, but it is not FDA-approved as a drug.
