Improving 24-hour Blood Pressure in Obstructive Sleep Apnea

Summary

This study examines the combined effects of an angiotensin receptor blocker (ARB), antioxidant supplementation, and continuous positive airway pressure (CPAP) therapy on the lowering of 24-hour blood pressure in persons with moderate to severe Obstructive Sleep Apnea (OSA). All participants will undergo CPAP therapy as prescribed by their doctor; however, half of the participants will receive the combined ARB and antioxidant treatment while the other half of the participants will receive a placebo.
