Abstract

The effect of pradigastat, a diacylglycerol acyltransferase-1 inhibitor, on the pharmacokinetics of acetaminophen, a gastric emptying marker, was evaluated. Twenty-five healthy subjects were enrolled and received 1000 mg acetaminophen with meal in Period 1, pradigastat (100 mg x 3 days followed by 40 mg x 7 days, one hour before meal) in Period 2, and 1000 mg acetaminophen at -2, -1, 0, +1, and +3 hours with respect to meal timing) in presence of steady-state pradigastat (40 mg maintenance dose) during Periods 3-7. The rate and extent of acetaminophen exposure were not affected when given at various time points with respect to pradigastat/meal timing. The Tmax of acetaminophen increased from 0.75 hours to 2.00 hours without affecting Cmax and AUC when administered one hour after food. Therefore, pradigastat is unlikely to affect the pharmacokinetics of drugs whose absorption is dependent on the rate of gastric emptying when co-administered.
