Long Term Effect of Buspirone on Esophageal Function and Esophageal Symptoms in Patients With Systematic Sclerosis (SSc)

Summary

Esophagus is commonly affected in Systemic Sclerosis (SSc) and esophageal function is compromised in about 75% of patients. Previous studies have shown that buspirone, an orally available 5-HT1A (serotonin 1a receptor agonist), enhances esophageal motility in healthy volunteers. Recently, the investigators observed that a single dose of buspirone (10mg) improves lower esophageal sphincter (LES) function in patients with SSc and esophageal involvement . Objectives: To evaluate the effect of continuous administration of buspirone on esophageal dysfunction and related symptoms in SSc using high resolution manometry (HRM).
