NCT ID NCT05804084
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether acetazolamide, a cheap and well-tolerated diuretic, can help people with obstructive sleep apnea who cannot use a CPAP mask. Sixty adults with moderate to severe sleep apnea will receive either the drug or a placebo for 4 weeks each. Researchers will measure sleep apnea severity, memory, and quality of life to see if this pill offers a new treatment option.
