Abstract
Obstructive sleep apnea (OSA) is a common chronic breathing disorder associated with reduced quality of life. Given the rising prevalence of obesity, the leading risk factor for this condition, OSA is an important public health concern. Noninvasive continuous positive airway pressure (CPAP) is first-line therapy for OSA. Despite the benefits of consistent CPAP use, adherence remains a challenge. CPAP machines and accessories are sold in community pharmacies and home healthcare settings. It is increasingly important that pharmacists understand the principles of OSA and CPAP therapy to optimize pharmacotherapy with this disorder and reinforce CPAP compliance.
