Low-dose trazodone for symptomatic patients with esophageal contraction abnormalities. A double-blind, placebo-controlled trial

Twenty-nine patients with esophageal symptoms and contraction abnormalities of the esophageal body completed a 6-wk, double-blind, placebo-controlled trial of trazodone (100-150 mg/day). Measures of esophageal and psychologic symptoms were completed at entry and at each follow-up visit. Esophageal manometry was repeated at the termination of the trial. Upon completion of the treatment, patients receiving trazodone (n = 15) reported a significantly greater global improvement than those receiving placebo (n = 14; p = 0.02). Although a variable clinical response was observed, the trazodone group had less residual distress over esophageal symptoms compared with the placebo group (59% +/- 9% vs. 108% +/- 19%, p = 0.03). Manometric changes observed during the course of the trial were not influenced by treatment nor by clinical response. Remarkable reductions in ratings of chest pain were reported by both treatment groups, emphasizing the importance of controlled trials when studying this patient population. We conclude that low-dose trazodone therapy can be of benefit in the management of symptomatic patients with esophageal contraction abnormalities. In addition, our findings support recent observations that manometric abnormalities characterizing this patient group may not be solely responsible for symptoms.
