Acetazolamide as an adjunct to CPAP treatment: a case of complex sleep apnea in a patient on long-acting opioid therapy.
A 41-year-old white woman on long-acting opioid therapy was diagnosed with moderate obstructive sleep apnea. On initiation of continuous positive airway pressure (CPAP), she manifested severe central apnea that was unresponsive to supplemental oxygen and interfered with CPAP titration. Acetazolamide, 250 mg, nightly at bedtime was initiated, and CPAP titration was repeated. On acetazolamide, optimal CPAP pressure was obtained with no manifestation of clinically significant central respiratory disturbance. This case suggests that acetazolamide may be an effective adjunct to positive airway pressure therapy in patients on long-acting opioids. A need exists for examination of acetazolamide in this capacity.
