NCT03720353

Brief Summary

Currently, there is no pharmacological intervention capable of maintaining airway patency for the treatment of snoring and airflow limitation during sleep. Here we study the effect of pharmacological stimulation of the pharyngeal muscles on snoring severity, in a randomized quadruple-blind, crossover study.

Eligibility Criteria

Age18 Years - 79 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Age 18-79 yrs
  • Self-reported habitual snoring ("most of the time" or "all of the time" on Snoring Self-Evaluation Scale)
  • Sleep-related symptoms defined by any of the following\*:
  • Visual-Analog Scale for Sleep Quality ≤7/10 ("reduced sleep quality")
  • Epworth Sleepiness Scale ≥10 ("excessive daytime sleepiness")
  • Functional Outcomes of Sleep Questionnaire \<18 ("reduced sleep-related quality of life").
  • Presence of a bed-partner who is able to provide feedback to the participant on snoring (Snoring Bed-Partner Evaluation Scale)
  • The intention of these criteria is to enable participants with a broad range of possible snoring symptoms to be included. We note that the Visual-Analog Scale for Sleep Quality is, on average, approximately 7/10 in patients with sleep apnea; thus, we consider a value at or below 7 to indicate "reduced sleep quality".

You may not qualify if:

  • Known obstructive sleep apnea (OSA, except "mild")
  • Current treatment for OSA or snoring (continuous positive airway pressure, oral appliances, supplemental oxygen)
  • Use of medications expected to stimulate or depress respiration (including opioids, barbiturates, acetazolamide, doxapram, almitrine, theophylline, 4-hydroxybutanoic acid).
  • Use of similar medications to the study drugs.
  • Conditions likely to affect obstructive sleep apnea physiology: neuromuscular disease or other major neurological disorder, heart failure (also below), or any other unstable major medical condition.
  • Respiratory disorders other than sleep disordered breathing:
  • o chronic hypoventilation/hypoxemia (awake oxygen saturation \< 92% by oximetry) due to chronic obstructive pulmonary disease or other respiratory conditions.
  • Other sleep disorders: periodic limb movements (periodic limb movement arousal index \> 10/hr), narcolepsy, or parasomnias.
  • Contraindications to the study drugs, including:
  • clinically-significant kidney disorders (eGFR\<60 ml/min/1.73m2)
  • clinically-significant liver disorders
  • clinically-significant cardiovascular conditions
  • severe hypertension (systolic blood pressure above 180 mmHg or diastolic below 110 mmHg measured at baseline)
  • cardiomyopathy (left ventricular ejection fraction, LVEF\<50%) or heart failure
  • advanced atherosclerosis
  • +10 more criteria
