Summary

This trial will test a new treatment to reduce severity of OSA, a highly prevalent disorder with serious consequences. It will look at the effect of Acetazolamide on REM and nREM OSA and on ventilatory parameters.

Who is the study for?
This trial is for people with REM sleep apnea who haven't used CPAP for over a week. Participants should have more severe symptoms during REM than non-REM sleep and not be on any medication that affects breathing or have conditions like uncontrolled medical issues, major neurological disorders, heart failure, respiratory diseases other than sleep apnea, or be pregnant.
What is being tested?
The study tests if Acetazolamide can help with REM-related obstructive sleep apnea by improving muscle activity in the airway and breathing drive during sleep. It's compared to a placebo capsule to see if there's a real effect.
What are the potential side effects?
Acetazolamide may cause side effects such as acidosis (too much acid in the body), low potassium levels, low sodium levels, adrenal gland problems, kidney function impairment, allergic reactions if sensitive to sulfa drugs, liver disease complications.
