Acetazolamide for Central Sleep Apnea in Opioid Use Disorder

This study is looking at whether a medication called acetazolamide can help people who have central sleep apnea (CSA) caused by medicines they take for opioid use disorder (MOUD). CSA is a condition where your breathing repeatedly stops and starts during sleep. The study will compare acetazolamide to a placebo (an inactive pill) over 7 days. We want to see if acetazolamide improves your breathing during sleep. You can join if you are between 18 and 100 years old, have CSA while on MOUD, and meet other health requirements. The study aims to enroll 40 participants, but its current status is unclear.

Study design
This is an interventional study that will randomize 40 participants to receive either acetazolamide or a placebo.
What's involved
You would take either acetazolamide or a placebo daily for 7 days, and have an overnight sleep study at the end of this period.
Compensation
Not stated in the trial record.
Follow-up
Your central apnea index will be measured at 7 days.
