NCT00539240

Brief Summary

The purpose of this project is to compare the efficacy (how successful) 1) standard-dose proton pump inhibitor (PPI) (rabeprazole 20 mg once daily) (a medication that completely blocks the stomach from producing acid) plus low dose tricyclic antidepressant (nortriptyline 50mg) (TCA); 2) double-dose PPI (rabeprazole 20 mg twice a day); to 3) standard-dose PPI (rabeprazole 20mg once daily) and placebo (an inactive substance, like a sugar pill) to determine the relative symptom resolution and health-related quality of life in gastroesophageal reflux disease (a disease characterized by a burning sensation (heartburn) behind the breast bone caused by a backflow of stomach contents into the esophagus) (GERD) patients who fail standard-dose PPI and you will be randomly assigned (similar to flipping a coin) to one of the three groups.

Limitations and Caveats

Recruitment challenges, including difficulty finding patients who "fail" PPI but had not already been prescribed doubled dose. Necessitated a no-cost extension to complete recruitment
