| 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. | 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. |
