Once-daily pantoprazole 40 mg and esomeprazole 40 mg have equivalent overall efficacy in relieving GERD-related symptoms

Abstract

Aim: To compare the efficacy of pantoprazole and esomeprazole for the treatment of gastro-oesophageal reflux disease- (GERD-) related symptoms.

Methods: In this multicentre, randomized, double-blind study 217 patients [intention-to-treat (ITT) population] diagnosed with endoscopically proven GERD grade B/C received pantoprazole (40 mg once daily (o.d.), n = 112] or esomeprazole (40 mg o.d/, n = 105) for 4 weeks. Patients recorded GERD-related symptoms (daytime and night-time) using diaries (daily), and/or by telephone interviews (every third day) and completed the Gastrointestinal Symptom Rating Scale (GSRS) questionnaire. The area under the time curve (AUC) for the sum score of GERD-related symptoms (symptom load of each patient during the treatment) and the time to reach adequate relief from GERD-related symptoms were calculated.

Results: Patients reported first adequate relief from daytime GERD-related symptoms after a mean of 3.7 (pantoprazole) and 5.9 days (esomeprazole) (P = 0.034); the values for the night-time were 1.7 and 3.5 days, respectively (P = 0.012, ITT). The AUCs for the single symptoms and the sum scores were comparable.

Conclusions: Treatment with pantoprazole resulted in significantly faster first-time relief from daytime and night-time GERD-related symptoms than esomeprazole. Pantoprazole and esomeprazole were similar with respect to reduction of load of GERD-related symptoms.
