donepezil and Sleep Apnea, Obstructive

donepezil has been researched along with Sleep Apnea, Obstructive in 4 studies

Donepezil: An indan and piperidine derivative that acts as a selective and reversible inhibitor of ACETYLCHOLINESTERASE. Donepezil is highly selective for the central nervous system and is used in the management of mild to moderate DEMENTIA in ALZHEIMER DISEASE.
donepezil : A racemate comprising equimolar amounts of (R)- and (S)-donepezil. A centrally acting reversible acetylcholinesterase inhibitor, its main therapeutic use is in the treatment of Alzheimer's disease where it is used to increase cortical acetylcholine.
2-[(1-benzylpiperidin-4-yl)methyl]-5,6-dimethoxyindan-1-one : A member of the class of indanones that is 5,6-dimethoxyindan-1-one which is substituted at position 2 by an (N-benzylpiperidin-4-yl)methyl group.

Sleep Apnea, Obstructive: A disorder characterized by recurrent apneas during sleep despite persistent respiratory efforts. It is due to upper airway obstruction. The respiratory pauses may induce HYPERCAPNIA or HYPOXIA. Cardiac arrhythmias and elevation of systemic and pulmonary arterial pressures may occur. Frequent partial arousals occur throughout sleep, resulting in relative SLEEP DEPRIVATION and daytime tiredness. Associated conditions include OBESITY; ACROMEGALY; MYXEDEMA; micrognathia; MYOTONIC DYSTROPHY; adenotonsilar dystrophy; and NEUROMUSCULAR DISEASES.

Trial Overview

Trial Outcomes

Apnea Hypopnea Index (AHI)

The Apnea-Hypopnea Index or Apnoea-Hypopnoea Index (AHI) is an index used to indicate the severity of sleep apnea. It is represented by the number of apnea and hypopnea events per hour of sleep. The apneas (pauses in breathing) must last for at least 10 seconds and be associated with a decrease in blood oxygenation. A higher AHI value indicates more severe sleep apnea (NCT02264353)
Timeframe: 14 days (during overnight sleep study after donepezil or placebo is given)

Loop Gain

The sensitivity of the ventilatory control system (loop gain) was quantified by fitting a simplified mathematical model to the spontaneous ventilatory pattern of obstructive sleep apnea (OSA). The sensitivity of the ventilatory control system (loop gain) was quantified by fitting a simplified mathematical model to the spontaneous ventilatory pattern of OSA 21. Loop gain is reflected in the size of the ventilatory overshoot following a ventilatory perturbation (hypopnea/apnea), where loop gain = response/disturbance. Ventilatory fluctuations are estimated using the square-root transformed nasal pressure waveform. Loop gain was reported as the ventilatory response to a 1 cycle/min disturbance (LG1); a value of LGn>1 yields periodic central apnea. Calculations were performed using MATLAB (NCT02264353)
Timeframe: 14 days (during overnight sleep study after donepezil or placebo is given)

Respiratory Arousal Threshold

Arousal Threshold was measured as the average nadir epiglottic airway pressure immediately before electroencephalogram (EEG) arousal. It was measured with an epiglottic pressure catheter. The epiglottic catheter/balloon is linked in a pressure catheter inserted through the de-congested, anesthetized nostril and the tip of the catheter located at hypopharyngeal area. (NCT02264353)
Timeframe: 14 days (during overnight sleep study after donepezil or placebo is given)
