RATIONALE: Quetiapine is commonly prescribed "off-label" to people with insomnia symptoms. People with undiagnosed obstructive sleep apnea (OSA) frequently report insomnia symptoms, particularly difficulty maintaining sleep. In 2023, 10.7 million prescriptions were dispensed for quetiapine in the United States. Yet, there is limited information regarding the effects of quetiapine on sleep, breathing, and next-day performance in people with OSA.
OBJECTIVES: To determine the effects of 50 mg of quetiapine versus placebo on OSA severity and other polysomnographic parameters plus next-day vigilance and driving simulator performance in people with OSA who also reported difficulty maintaining sleep.
METHODS: We performed a double-blind, randomized, placebo-controlled, cross-over study (NCT05303935) in 15 people with OSA and difficulty maintaining sleep. Participants were studied overnight via polysomnography twice approximately 1 week apart and received either 50 mg of quetiapine or placebo (order randomized) just prior to sleep. A 10-minute psychomotor vigilance task (PVT) and 30-minute driving simulator test were performed each morning.
RESULTS: Compared to placebo, quetiapine reduced the apnea/hypopnea index (primary outcome) (mean ± SD: 27 ± 16 vs 20 ± 12 events/hour, P = .009), arousal index (32 ± 16 vs 25 ± 9 arousals/hour, P = .012), and increased sleep efficiency (80 ± 11 vs 87 ± 9%, P <.001) without worsening hypoxemia (mean overnight oxygen saturation: 94.7 ± 1.2% vs 94.5 ± 1.5%, P = .38). However, next-morning vigilance (median PVT reaction time: 336 ± 48 vs 382 ± 84 ms, P = .008) and driving simulator performance (steering deviation: 72 ± 38 vs 96 ± 53 cm, P <.01) were significantly impaired with quetiapine.
CONCLUSIONS: Consistent with a hypnotic effect, a single night of low-dose quetiapine reduced OSA severity as measured via the apnea/hypopnea index and increased sleep efficiency without worsening overnight hypoxemia. However, there was evidence of next-day impairment in vigilance and driving simulator performance.
