Treatment of severe snoring with a combination of pseudoephedrine sulfate and domperidone.

Study Objectives: Pharmacologic treatment of severe snoring has not been considered to be of great value. The objective of this study was to determine whether the combination of a nasal decongestant and a prokinetic drug would decrease or eliminate severe snoring. Methods: Thirty healthy individuals whose sleeping partners reported that the patients had severe nightly snoring entered an open-label trial of 60 mg of pseudoephedrine and 10 mg of domperidone at bedtime for 30 days. Each night's snoring was scored on a diary by the sleeping partner. At the end of the open-label trial, a subset of subjects whose snoring had recurred were randomized to one or both placebo-controlled trials, either 60 mg of pseudoephedrine sulfate plus 10 mg of domperidone or to 30 mg of pseudoephedrine sulfate plus 10 mg of domperidone. In another placebo-controlled trial, the drug combination was compared with each component. Results: In the open-label trial, 493 of 772 evaluable subject-nights were free of snoring; another 232 nights were scored as mild snoring. In the placebo-controlled trials, low-dose therapy caused a reduction in snoring, and high-dose therapy even a greater reduction in snoring. The drug combination was more effective than either agent alone. Conclusion: Treatment with a prokinetic agent plus a nasal decongestant reduced or eliminated severe snoring in the majority of subjects treated.
