Sleep disordered breathing in patients receiving therapy with buprenorphine/naloxone

Abstract

Patients using chronic opioids are at risk for exceptionally complex and potentially lethal disorders of breathing during sleep, including central and obstructive apnoeas, hypopnoeas, ataxic breathing and nonapnoeic hypoxaemia. Buprenorphine, a partial m-opioid agonist with limited respiratory toxicity, is widely used for the treatment of opioid dependency and chronic nonmalignant pain. However, its potential for causing sleep disordered breathing has not been studied. 70 consecutive patients admitted for therapy with buprenorphine/ naloxone were routinely evaluated with sleep medicine consultation and attended polysomnography. The majority of patients were young (mean-SD age 31.8±12.3 years), nonobese (mean-SD body mass index 24.9±5.9 kgm-2) and female (60%). Based upon the apnoea/hypopnoea index (AHI), at least mild sleep disordered breathing (AHI o5 events?h-1) was present in 63% of the group. Moderate (AHI 15
