About this study

Obstructive sleep apnea (OSA) is a severe type of snoring causing people to choke in their sleep. It affects millions of Americans, causing many health problems. For example, patients with OSA often feel very sleepy and are at risk of falling asleep while driving. OSA also causes elevated blood pressure, memory problems and can severely affect quality of life. Patients with OSA are often treated with a face-mask that helps them breath at night but can be difficult to tolerate. In fact, about half the patients eventually stop using this mask. Because there are few other treatments (and no drug therapy), many OSA patients are still untreated. Acetazolamide (a mild diuretic drug) has been used for over 50 years to treat many different conditions and is well tolerated. Recent data suggest, that acetazolamide may help OSA patients to not choke in their sleep and lower their blood pressure. Further, its low cost (66¢/day) and once-daily dosing may be attractive for OSA patients unable or unwilling to wear a mask each night. But previous studies had many limitations such as studying acetazolamide for only a few days and not capturing important outcomes. The goal of this study is to test if acetazolamide can improve sleep apnea, neurocognitive function and quality of life in adults with OSA, and to assess how it does that. Thus, the investigators will treat 60 OSA patients with acetazolamide or placebo for 4 weeks each. The order in which participants receive the drug or placebo wil…
