Fexofenadine Use in Gastroesophageal Reflux Symptoms

Status Terminated

Clinical Trial Summary

The investigators wish to study the effectiveness of Fexofenadine (an over the counter allergy pill) for the treatment of gastroesophageal reflux symptoms in patients who still have symptoms despite being on a proton pump inhibitor. The investigators will do this by giving participants both Fexofenadine (an H1 blocker) for 2 weeks and placebo (sugar pill) for 2 weeks. The participants will not know which drug they are getting at a particular time. This will help the investigators better assess the true effectiveness of Fexofenadine.

Clinical Trial Description

Around 18-28% of North American adults have gastroesophageal reflux symptoms once per week. Of those patients up to 60% may have an inadequate response to proton pump inhibitors and have persistent symptoms. One possible explanation is that this group of patients has nerve related pain. It is thought that H1 receptor activation may sensitize the gastrointestinal tract and esophagus to pain. H1 blockers such as anti-histamines may play a role in treatment of gastroesophageal reflux symptoms that are refractory to proton pump inhibitors by reducing pain perception. The investigators wish to conduct a randomized control trial to test this hypothesis. The investigators will do this by giving participants both Fexofenadine (an H1 blocker) for 2 weeks and placebo (sugar pill) for 2 weeks. The participants will not know which drug they are getting at a particular time. This will help the investigators better assess the true effectiveness of Fexofenadine. ;
