A comparison of lansoprazole and ranitidine in the treatment of erosive oesophagitis. Multicentre Investigational Group
Abstract
BACKGROUND: Lansoprazole is a new proton pump inhibitor which produces prolonged decrease of gastric acidity. The aim of this study was to compare lansoprazole to a standard dose of ranitidine in the treatment of patients with reflux oesophagitis.
METHODS: Two hundred and forty-seven patients with erosive oesophagitis were randomly assigned to 8 weeks of treatment with either 30 mg lansoprazole once daily or 150 mg ranitidine twice daily.
RESULTS: Two hundred and forty-two patients were included in the analysis. Lansoprazole (30 mg) daily, healed oesophagitis in 92.1% of patients after 8 weeks of treatment. This was significantly superior to 150 mg ranitidine b.d.s. which healed oesophagitis in 69.9% of patients (P < 0.001). Relief of reflux symptoms was superior with lansoprazole to that with ranitidine. Both lansoprazole and ranitidine were well tolerated with no serious drug-related adverse events noted.
CONCLUSION: Lansoprazole, 30 mg once daily, is highly effective and safe in the short-term treatment of erosive oesophagitis.
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.
