Treatment of Patients With Persistent Heartburn Symptoms: A Double-Blind, Randomized Trial

Background & Aims: Common treatment practices in patients who continue to be symptomatic on proton pump inhibitor once-daily treatment include either increasing the dosage or the use of supplemental medication. This trial's purpose was to compare 2 therapeutic strategies, increasing the proton pump inhibitor dosage to twice daily versus switching to another proton pump inhibitor, in patients with persistent heartburn while receiving standard-dose proton pump inhibitor therapy. Methods: This multicenter, randomized, double-blind, double-dummy trial included patients with persistent heartburn symptoms while receiving therapy with lansoprazole 30 mg once daily. Patients were randomly assigned to treatment for 8 weeks with either single-dose esomeprazole (40 mg once daily) (n = 138) or lansoprazole 30 mg twice daily (n = 144). The primary efficacy variable was the percentage of heartburn-free days from day 8 to the end of treatment. Results: Single-dose esomeprazole was at least as effective as twice-daily lansoprazole for the primary end point of percentage of heartburn-free days during the study period (54.4% and 57.5%, respectively). Symptom scores improved from baseline in similar numbers of patients for heartburn (83.3% of patients in each group), acid regurgitation (76.8% vs 72.9%, P = .58), and epigastric pain (67.4% vs 61.1%, P = .32), and rescue antacid use was also similar (0.4 tablets/day vs 0.5 tablets/day, P = .50). Conclusions: Switching patients with persistent heartburn on a standard-dose proton pump inhibitor to a different proton pump inhibitor was as effective as increasing the proton pump inhibitor dosage to twice daily for controlling heartburn symptoms.
