How it works

Gabapentin binds to the alpha-2-delta subunit of voltage-gated calcium channels in the central nervous system, which may calm overactive temperature regulation and reduce hot flash frequency. Pregabalin binds the same target but NAMS 2023 does not recommend it for hot flashes.

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.
