Meta AnalysisHypnotics on Obstructive Sleep Apnea Severity and Endotypes: A Systematic Review and Meta-Analysis.
Rationale: Low arousal threshold and poor muscle responsiveness are common determinants of obstructive sleep apnea (OSA). Hypnotics were hypothesized as an alternative OSA treatment via raising the arousal threshold and possibly genioglossus responsiveness. Objectives: To examine the effect of common hypnotics on arousal threshold, OSA severity, and genioglossus responsiveness. ⋯ However, people with very low arousal threshold or those who exhibited a 0-25% arousal threshold increase from placebo experienced the greatest, yet still modest, post-treatment AHI reductions (∼10%). Hypnotics did not affect genioglossus responsiveness (high QoE). Conclusions: Further research testing or clinical use of hypnotics as OSA alternative treatments should be discouraged, unless in the presence of comorbid insomnia or as part of combination therapy in individuals with very low arousal threshold.
