title: Effect of nicardipine on gastric acid secretion in man.
abstract: The effect of nicardipine on basal and pentagastrin-stimulated gastric acid secretion in normal volunteers was investigated. When compared with saline, an intravenous infusion of nicardipine caused a significant decrease in peak acid output (from 37.8 mmol hour-1 to 28.8 mmol hour-1; P = 0.04) and a small reduction in aspirate volume. Nicardipine had no significant action on basal acid output or volume of aspirate. Proteolytic activity in both the basal and stimulated periods was unaffected by nicardipine as were serum gastrin concentrations. Although calcium channel blocking agents are theoretically antisecretory the present study suggests they are unlikely to have clinically useful therapeutic actions.
