title: Prevention of duodenal ulcer recurrence with 15 mg lansoprazole: a double-blind placebo-controlled study. The Lansoprazole Study Group.
abstract: Although eradication of Helicobacter pylori cures duodenal ulcer, some patients are not infected and others are treatment failures. This randomized, double-blind, placebo-controlled study assessed the value of treatment with low-dose lansoprazole in preventing duodenal ulcer recurrence. One hundred eighty-six patients with endoscopic documentation of healed duodenal ulcer received 15 mg/day lansoprazole or placebo for 12 months or until ulcer recurred. Endoscopy results, symptom assessment, and fasting serum gastrin levels were obtained at multiple time points. Densities of E, EC, and G cells were assessed by biopsy when the ulcer recurred or at the final visit. Time to ulcer recurrence was significantly longer (P < 0.001) in the lansoprazole group (median >12 months) compared to placebo (median <3 months), and patients taking lansoprazole were asymptomatic longer (P < 0.05). Maintenance therapy with lansoprazole 15 mg/day suppresses acid and controls recurrence of duodenal ulcer disease.
