Systematic review: maintenance treatment of gastro‐oesophageal reflux disease with proton pump inhibitors taken ‘on‐demand’
Abstract
BACKGROUND: Proton pump inhibitors (PPI) therapy 'on-demand' is often used as an alternative to continuous maintenance therapy in gastro-oesophageal reflux disease (GERD). AIM: We conducted a systematic review with the specific objectives to ascertain whether on-demand PPI therapy was effective in preventing symptomatic relapse and to assess the relative efficacy of on-demand vs. continuous PPI maintenance strategy. METHODS: Randomized-controlled clinical trials comparing on-demand PPI vs. placebo or on-demand vs. continuous PPI therapy in GERD patients were identified by searching the Medline database and the Cochrane Controlled Trials Register. RESULTS: Seventeen studies were found which met inclusion criteria. Out of the 17 studies: five investigated exclusively patients with non-erosive reflux disease (NERD), four patients with NERD and mild oesophagitis, two patients with erosive oesophagitis only, and two patients with uninvestigated GERD symptoms, respectively. Four further studies were not investigating the effectiveness of the therapies but primarily pharmacoeconomic or quality of life parameters. CONCLUSIONS: On the basis of the analysis of 17 studies, we can conclude that on-demand therapy with currently available PPI appears to be effective in the long-term management of patients with NERD or mild and uninvestigated forms of GERD, but not in patients with (severe) erosive oesophagitis.
