Summary The effects of three gastric antisecretory drugs on the pharmacokinetics of ethanol have been studied in a randomized crossover experiment. Male medical students (n=12) took ethanol 0.8 g/kg body weight at 08.00 h after an overnight fast. On seven successive days before drinking ethanol they were given omeprazole 20 mg, cimetidine 800 mg, ranitidine 300 mg, or no drug, with a period of at least 7 days between treatments. The peak blood ethanol concentration of 21.9 to 22.8 mmol·l−1 occurred at 64 to 70 min after the end of drinking. The rate of disappearance of ethanol from the blood ranged from 3.0 to 3.3 mmol·l−1·h−1 and the rate of removal from the whole body ranged from 8.0 to 8.5 g·h−1. The apparent volume of distribution of ethanol was almost the same for all four treatments: mean 0.68 l·kg−1, corresponding to a mean total body water of 441 (59% body weight). Mean areas under the concentration-time profiles of ethanol ranged from 83 to 87 mmol·l−1·h for the four treatments. It is concluded that omeprazole, cimetidine and ranitidine do not alter the kinetics of a moderate dose of ethanol.
