Summary
This study tested whether the drug acetazolamide can improve sleep-disordered breathing in 39 adults with chronic pain who use opioids. Participants took either the drug or a placebo for one week each. The goal was to see if the pill could reduce sleep apnea events as an alternative to CPAP machines.
