Management of symptoms in step-down therapy of gastroesophageal reflux disease
Abstract
OBJECTIVE: Majority of studies on gastroesophageal reflux disease (GERD) that include patients with or without erosive disease have documented the efficacy of proton pump inhibitors (PPIs) as well as their superiority to H(2)-receptor antagonist (H(2)-RA). The purpose of this study was to clarify the difference in quality of GERD treatment with PPIs and H(2)-RA in step-down protocol using lansoprazole.
METHODS: Forty-three patients with reflux esophagitis were randomly divided into three groups and assessed by severity score; group 1 received 30 mg lansoprazole initially and maintenance therapy with a standard dose H(2)-RA; group 2 received 30 mg of lansoprazole initially and maintenance therapy of 15 mg lansoprazole; and group 3 received 15 mg of lansoprazole once daily for 16 weeks. If the patients experienced symptomatic recurrence while on H(2)-RA, they were switched to PPI maintenance.
RESULTS: Heartburn, regurgitation and dysphagia were hardly found in any group at 8 weeks after 15 mg or 30 mg lansoprazole treatment. After 8 weeks, however, heartburn and regurgitation recurred at 50% and 78.6%, respectively, in the stepped down to famotidine group, and quality of life (QOL) was significantly impaired. Endoscopic ultrasonography (EUS) analysis showed reduction of the submucosal layer without any change in the mucosal surface in the stepped down to famotidine group.
CONCLUSIONS: Step-down lansoprazole therapy is considered very effective in terms of rapid effect,…
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.
