Gastroesophageal Reflux
Conditions
Brief summary
To investigate if buspirone, a partial 5-HT-1A receptor agonist, is able to modify esophageal sensitivity, assessed by the multimodal stimulation.
Interventions
Administration of buspirone to assess esophageal sensitivity
Administration of placebo to assess differences in esophageal sensitivity
