Abstract

Chronic, nonproductive cough may result from enhanced sensitivity of the cough reflex. Often, this debilitating symptom is refractory to standard antitussive therapy. Baclofen, an agonist of gamma-aminobutyric acid (GABA), has been shown, in animals, to have antitussive activity via a central mechanism. Recently, in normal subjects, we have demonstrated the ability of baclofen to inhibit capsaicin-induced cough, as well as cough due to angiotensin-converting enzyme (ACE) inhibitors. Herein, we describe two patients with chronic, refractory cough who obtained symptomatic improvement after a 14-day course of low-dose, oral baclofen, administered in a double-blind, placebo-controlled manner. In addition, both subjects demonstrated significant increases in cough threshold to inhaled capsaicin after treatment with baclofen.
