Effect of doxapram on obstructive sleep apnea
Bulletin Europeen De Physiopathologie Respiratoire
|March 1, 1986
Summary
Doxapram hydrochloride improved obstructive sleep apnea by reducing average apnea length and improving oxygen saturation during breathing events. However, it did not reduce the overall number of disordered breathing events during sleep.
Area of Science:
- Sleep Medicine
- Respiratory Pharmacology
Background:
- Obstructive sleep apnea (OSA) is a common sleep disorder characterized by repeated episodes of upper airway collapse during sleep.
- Current treatments for OSA may not be effective for all patients, necessitating exploration of alternative therapeutic strategies.
Purpose of the Study:
- To investigate the efficacy of doxapram hydrochloride, a respiratory stimulant, in improving the clinical manifestations of obstructive sleep apnea.
Main Methods:
- A randomized, placebo-controlled study was conducted involving four patients diagnosed with obstructive sleep apnea.
- Patients received either a bolus of doxapram hydrochloride followed by a continuous infusion or a placebo during overnight polysomnography.
Main Results:
- Doxapram hydrochloride administration led to a significant improvement in average oxyhemoglobin desaturation during apneic and hypopneic episodes.
- The drug also decreased the average duration of apneas and hypopneas.
- No significant changes were observed in the average number of oxyhemoglobin desaturations per hour of sleep or overall sleep efficiency.
Conclusions:
- While doxapram hydrochloride at doses that increase ventilatory drive does not reduce the frequency of disordered breathing events in OSA patients, it can facilitate the termination of these events at higher oxyhemoglobin saturation levels.
- These findings suggest a potential role for doxapram in managing specific aspects of OSA, particularly in mitigating the severity of desaturation events.
