Proton Pump Inhibitors, H2-Receptor Antagonists and Prokinetics for Gastro-Oesophageal Reflux

Proton pump inhibitors are more effective than H2-receptor antagonists in empirical treatment of heartburn likely to be caused by gastro-oesophageal reflux and in endoscopy negative reflux disease. Level of evidence: "A"

A Cochrane review [Abstract] 1 included 34 studies (15 in the empirical treatment group, 15 in the endoscopy negative reflux disease group and 4 in both) with a total of 13140 participants.

In empirical treatment of gastro-oesophageal reflux disease (GORD), the relative risk (RR) for heartburn remission (the primary efficacy variable) in placebo-controlled trials for proton pump inhibitors (PPI) was 0.37 (2 trials, 95% CI 0.32 to 0.44), for H2-receptor antagonists (H2RA) 0.77 (2 trials, 95% CI 0.60 to 0.99) and for prokinetics 0.86 (1 trial, 95% CI 0.73 to 1.01). In a direct comparison PPIs were more effective than H2RAs (7 trials, RR 0.66, 95% CI 0.60 to 0.73) and prokinetics (two trials, RR 0.53, 95% CI 0.32 to 0.87).

In treatment of endoscopy negative reflux, the RR for heartburn remission for PPI versus placebo was 0.71 (ten trials, 95% CI 0.65 to 0.78) and for H2RA versus placebo was 0.84 (two trials, 95% CI 0.74 to 0.95). The RR for PPI versus H2RA was 0.78 (three trials, 95% CI 0.62 to 0.97) and for PPI versus prokinetic 0.72 (one trial, 95% CI 0.56 to 0.92).
