AIM To compare the safety and efficacy of pantoprazole and ranitidine in maintaining erosive oesophagitis healing. METHODS Gastro-oesophageal reflux disease patients (349) with endoscopically documented healed erosive oesophagitis (grade 0 or 1) were randomly assigned to receive pantoprazole (10, 20 or 40 mg/q.d.s.) or ranitidine (150 mg/b.d.). Erosive(More)
BACKGROUND & AIMS Parenteral control of gastric acid hypersecretion in conditions such as Zollinger-Ellison syndrome (ZES) or idiopathic gastric acid hypersecretion is necessary perioperatively or when oral medications cannot be taken for other reasons (e.g., during chemotherapy, acute upper gastrointestinal bleeding, or in intensive care unit settings).

Tolrestat is a well tolerated nonhydantoin aldose reductase inhibitor that has been reported to improve nerve conduction in diabetic animals and humans. Its effects on nerve biochemistry and structure have not been studied in patients with diabetic neuropathy. Patients with advanced diabetic neuropathy treated with long-term open-label tolrestat were(More)
OBJECTIVES In patients with Zollinger-Ellison syndrome (ZES) or other conditions requiring oral doses of proton pump inhibitors, it frequently becomes necessary to use parenterally administered gastric acid inhibitors. However, i.v. histamine-2 receptor antagonists are not effective at usual doses and lose their effectiveness because of tachyphlaxis. With(More)
OBJECTIVES The aim of this dose-response study was to compare the effectiveness of 10 mg, 20 mg, and 40 mg of pantoprazole with that of placebo tablets in the healing and symptom relief of gastroesophageal reflux disease associated with erosive esophagitis, and to determine the optimal dose. METHODS A total of 603 patients with endoscopically confirmed(More)
A double-blind, placebo-controlled clinical trial was conducted to study the effects of discontinuing tolrestat, an aldose reductase inhibitor, on peripheral sensorimotor diabetic neuropathy. After an average of 4.2 years of continuous tolrestat use, 372 patients were randomly assigned to either placebo or continued tolrestat therapy and were followed for(More)
OBJECTIVE Maintenance proton pump inhibitor (PPI) therapy is effective for gastric acid hypersecretory states, although data with pantoprazole are limited. The aim of this study was to evaluate the safety and efficacy of long term p.o. pantoprazole in individuals with hypersecretion. METHODS All subjects had Zollinger-Ellison syndrome or idiopathic(More)
Hepatic cholesterol synthesis was studied in rats after consuming diets of varying neutral lipid and cholesterol content. Cholesterol synthesis was evaluated by measuring 3-hydroxy-3-methylglutaryl-CoA reductase and by determining the rate of 3H-labeled sterol production from [3H]mevalonate. Results were correlated with sterol balance data and hepatic lipid(More)
OBJECTIVES To compare the safety and efficacy of pantoprazole with ranitidine for the maintenance of endoscopically documented healed (grade 0 or 1) erosive oesophagitis. METHODS Patients (371) were randomly assigned to receive pantoprazole 10, 20 or 40 mg or ranitidine 150 mg. Endoscopies were performed after 1, 3, 6 and 12 months or when symptoms(More)
