Background:
Rabeprazole sodium is the most recent member of a class of substituted benzimidazole molecules known as proton pump inhibitors. Other proton pump inhibitors have been shown to be effective in healing oesophagitis.
Methods:
In this randomised, double‐blind, multicentre study, conducted at 27 European sites, the efficacy and safety of rabeprazole and omeprazole were compared in patients with erosive or ulcerative gastro‐oesophageal reflux disease (GERD).100 patients received rabeprazole 20 mg, and 102 patients omeprazole 20 mg once daily for 4 or 8 weeks, with healing monitored by endoscopy.
Results:
Overall GERD healing rates observed and evaluated at weeks 4 and 8 were equivalent. Four‐week healing rates for rabeprazole and omeprazole were 81%–81% and 92%–94% for 8‐week healing. Rabeprazole‐treated patients had similar relief of the frequency and intensity of heartburn to those treated with omeprazole. Both drugs were well tolerated over the 8‐week treatment period. Mean changes in fasting serum gastrin were comparable. No significant differences in laboratory parameters were seen. Biopsies for argyrophil ECL cell histology at the end‐point revealed a similar distributions of hyperplasia grades to those at baseline in both groups. Biopsies of body and antral mucosa for other parameters were similar between treatments for Helicobacter pylori colonization, presence or degree of inflammation, atrophy or intestinal metaplasia at the end‐point.
Conclusion:
In this study, GERD healing rates following rabeprazole 20 mg once daily were equivalent to those obtained with omeprazole 20 mg once daily. Both treatments resulted in a comparable relief of the frequency and intensity of heartburn associated with this disease, and both were well tolerated.
Background:
Rabeprazole sodium is the newest member of a class of substituted benzimidazole molecules known as proton pump inhibitors. Other proton pump inhibitors have been shown to be effective in healing active duodenal ulcer.
Method:
This randomized, double‐blind, multicentre study, conducted at 25 European sites, compared the efficacy and tolerability of rabeprazole and omeprazole in patients with active duodenal ulcers. One hundred and two patients with active duodenal ulcer received rabeprazole 20 mg and 103 patients omeprazole 20 mg once daily for 2 or 4 weeks, with ulcer healing monitored by endoscopy.
Results:
After 2 weeks, complete ulcer healing was documented in 69% of patients given rabeprazole 20 mg and in 62% of patients given omeprazole 20 mg (N.S.). After 4 weeks, healing rates were 98% in the rabeprazole group and 93% in the omeprazole group (P = 0.083). Rabeprazole‐treated patients had significantly greater improvement in daytime pain symptom relief than those treated with omeprazole at the conclusion of the study (P = 0.038). Both drugs were well tolerated over the 4‐week treatment period. Mean changes from baseline to end‐point in fasting serum gastrin were significantly greater in the rabeprazole group, but at end‐point mean values were well within normal limits for both groups. No clinically meaningful changes or other between‐group differences were observed in laboratory parameters.
Conclusion:
In this study, rabeprazole produced healing rates equivalent to omeprazole at weeks 2 and 4, and provided significantly greater improvement in daytime pain. Both treatments were well tolerated.
For patients taking NSAIDs continually, pantoprazole 20 mg o.d., pantoprazole 40 mg o.d., or omeprazole 20 mg o.d. provide equivalent, effective, and well-tolerated prophylaxis against GI lesions, including peptic ulcers.
Aims: To compare safety and efficacy of on-demand pantoprazole 20 mg/40 mg versus placebo in the long-term management of patients with mild gastroesophageal reflux disease (GERD) after heartburn relief. Methods: A total of 634 patients with endoscopically confirmed GERD grade 0/I and heartburn were included. During the acute phase, patients were treated with pantoprazole 20 mg once daily for 4 weeks. Those patients relieved from heartburn entered the long-term phase, and were randomly assigned to either treatment group pantoprazole 20 mg, 40 mg or placebo. Over 6 months, patients took study medication on demand (antacids as rescue medication) and discontinued the drug once symptoms abated. Results: After 4 weeks a total of 87.1%/90.0% of patients were free of heartburn (ITT/PP), and entered the subsequent long-term phase. The perceived average daily symptom load (placebo: 3.93, pantoprazole 20 mg: 2.91, pantoprazole 40 mg: 2.71, ITT) and the number of antacid tablets taken (average number, placebo: 0.68, pantoprazole 20 mg: 0.45, pantoprazole 40 mg: 0.33, ITT) were significantly higher in the placebo than in both pantoprazole groups (p < 0.0001), with no statistically significant difference between the two pantoprazole groups. The discontinuation rate due to insufficient control of heartburn was significantly lower in both pantoprazole groups compared to placebo (placebo: 10.9, pantoprazole 20 mg: 2.8, pantoprazole 40 mg: 0.9, ITT). Conclusions: Our findings favor on-demand treatment with pantoprazole 20 mg for the long-term management of heartburn in patients with uncomplicated GERD (grade 0/I) with superiority to placebo.
