Could a 66-cent pill replace CPAP for sleep apnea?
NCT ID NCT05616260
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether acetazolamide, a cheap and well-tolerated water pill, can reduce sleep apnea severity and lower blood pressure in young adults (18–50 years old) who cannot or will not use a CPAP mask. 54 participants received either the drug or a placebo for two weeks each. The goal is to offer a simple, once-daily pill option for the millions of OSA patients who struggle with current treatments.
