Summary

This pilot study tests whether a drug called aprepitant (currently used for nausea) can lower a hormone called aldosterone in people with severe sleep apnea and high blood pressure. The study will enroll 24 adults and measure aldosterone levels before and after taking the drug or a placebo. The goal is to understand if blocking a nerve signal in the adrenal gland can reduce blood pressure risks in sleep apnea.
