Sleep and Breathing in the General Population - Chemical Stimuli

Sleep-disordered Breathing Clinical Trial

Official title:
Sleep and Breathing in Health and Disease (Part 2A - Chemical Stimuli, Sleep and Breathing in the General Population)

Clinical Trial Summary

Central sleep apnea (CSA) is a common condition and its treatment remains elusive. The focus of this proposal is to identify the role of the physiologic path involving cortical arousals in CSA by decreasing arousal frequency using the pharmacological agent zolpidem. The goal is to identify the acute effects of administering zolpidem on sleep and respiratory outcomes, and subsequently, its effect on the severity of CSA and propensity to develop CSA. This study will shed light on the mechanisms underlying CSA that involve cortical arousals and will guide future therapeutic interventions for CSA.

Clinical Trial Description

The literature suggests that zolpidem may be effective in the treatment of central sleep apnea (CSA). However, evidence regarding the efficacy of zolpidem and the underlying mechanisms involved in its effect on CSA are not well-studied. Furthermore, respiratory-related arousals are hypothesized to contribute CSA symptoms and severity. The aim of the study is to determine the effect of decreasing respiratory-related arousals on the propensity to develop central apnea. The investigators hypothesize that administration of the nonbenzodiazepine hypnotic zolpidem will decrease the frequency of respiratory-related arousals, lower the central apnea-hypopnea index, and widen the CO2 reserve during sleep in patients with CSA compared to no treatment. Participants will complete a night study on a low dose of zolpidem and another night study without zolpidem in a crossover manner. The order of night studies is randomized. The results will help unveil the role of arousals in CSA and the acute effect of zolpidem on CSA severity and the propensity to CSA. ;
