Management of reflux esophagitis: does the choice of proton pump inhibitor matter?
Abstract
BACKGROUND: Proton pump inhibitors (PPIs) are the treatment of choice for reflux esophagitis (RE). The effectiveness of PPIs throughout RE management, from healing to maintenance, has not been fully studied.
AIM: To compare esomeprazole with lansoprazole or pantoprazole for RE management using a management model.
METHODS: Data from six studies comparing esomeprazole with lansoprazole or pantoprazole for healing (4-8 weeks) or maintenance of healing (6 months) of RE were incorporated into hypothetical management models to determine the proportion of patients in endoscopic remission after sequential healing and maintenance therapy, assuming that patients received the same PPI throughout. The number needed to treat (NNT) to achieve one more patient in remission with esomeprazole vs. other PPIs was estimated. The hypothetical model was validated using results from the EXPO study, which compared esomeprazole with pantoprazole for RE healing and maintenance.
RESULTS: Overall, esomeprazole 40 mg produced higher rates of healing (life-table estimates) than lansoprazole 30 mg (82.4-92.6% vs. 77.5-88.8%; p < 0.01) or pantoprazole 40 mg (95.5% vs. 92.0%; p < 0.001) and higher rates of endoscopic and symptomatic remission at 6 months than lansoprazole (83.0-84.8% vs. 74.0-75.9%; p < 0.001; life-table estimates) or pantoprazole (70.9% vs. 59.6%; p < 0.0001; observed rates). In the hypothetical management model, the NNT for esomeprazole was 9 vs. lansoprazole and 8 vs. pantoprazole. The…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design.
