A NK3 receptor blocker may emerge as an alternative to hormonal replacement therapy (HRT) for the treatment of hot flashes during menopause.
- Menopausal hot flashes are commonly treated with hormonal replacement therapy (HRT)
- Several women cannot or do not prefer to use HRT
- A new option that blocks NK3 receptors in the brain could emerge as an alternative for these women
The study included 37 women, out of which 28 completed the trial. The women were between 40 and 62 years of age and did not have a period in at least the previous year. They did not receive any other treatment for their hot flashes for at least 8 weeks before the study. Around half of them received a daily dose of 80 mg for 4 weeks, and a placebo for another 4 weeks with a gap of two weeks in between. The other half had the placebo first and then the drug.
The researchers found that:
- The number of hot flashes reduced by almost 73%
- The severity and impact of the hot flashes including that on sleep also reduced
- Side effects were minimal. Three women experienced rise in a liver enzyme, which normalized within 90 days of stopping treatment
