Study Summary

This trial looks at how transitioning from a high-sodium oxybate to a low-sodium one affects blood pressure in narcolepsy patients, to provide info for HCPs, patients, and payers.

Who is the study for?
Adults aged 18-70 with narcolepsy, currently treated with high-sodium oxybate and stable doses of any blood pressure or wakefulness medications for at least 6 weeks prior to the study. Participants must not be pregnant, breastfeeding, have unstable medical conditions, significant cardiovascular disease, or psychiatric disorders that could impact their safety or study results.Check my eligibility
What is being tested?
The trial is testing the effect on blood pressure when switching from high-sodium oxybate (XYREM) to a low-sodium version called XYWAV in people with narcolepsy. The goal is to see if reducing sodium intake through medication changes can improve blood pressure.See study design
What are the potential side effects?
While specific side effects are not listed here, participants may experience changes related to lower sodium levels and adjustments in sleep patterns due to the switch from one medication (high-sodium oxybate) to another (low-sodium XYWAV).
