Narcolepsy patients may see blood pressure benefits by switching to Low-Sodium oxybate

NCT ID NCT05869773

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study involved 155 adults with narcolepsy who were already taking a high-sodium oxybate medication. They switched to Xywav, a low-sodium version, to see if their blood pressure would improve. The goal was to provide doctors and patients with useful information about the impact of sodium content in narcolepsy treatments.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

Xywav (low-sodium oxybate)

What this could lead to

If successful, this study could show that switching to a low-sodium oxybate lowers blood pressure, offering a safer option for managing narcolepsy.

What could go wrong

This is a small, completed Phase 4 study with no placebo group, so results may not apply to everyone. Blood pressure changes may vary and not be clinically significant.
