Lack of first-pass metabolism of ethanol at blood concentrations in the social drinking range
Authors:J G Wagner
Abstract:Previously published data are displayed in a new manner and show that there is complete systemic availability of oral doses of 23-47 g of ethanol (0.35-0.75 g/kg or 30-60 ml of 95% ethanol) in man when administered in the fasting state relative to an intravenous infusion of the same doses administered over a 2-hr period. A previous report by other authors that oral ethanol (0.15 g/kg) in man had a mean systemic availability of only 29% is explained by the fact that the subjects were fed one hour prior to administration of the alcohol and that the intravenous dose was infused over only a 20 minute period.
