Alcohol metabolism in man: effect of intravenous fructose infusion on blood ethanol elimination rate following stimulation by phenobarbital treatment or chronic alcohol consumption.

Abstract

The effect of phenobarbital (PB) pretreatment and of chronic alcoholism on blood ethanol elimination rate (BEER) was investigated in man. In order to gain additional information concerning the mechanism of possible changes BEER was determined before and during intravenous infusion of fructose, a compound known to increase the NADH-oxidizing capacity of the liver and thereby stimulating alcohol oxidation rate. Following PB-treatment (300 mg/day for 5-6 days, n = 8) a marked increase in unstimulated (U-) BEER was obtained. But the fructose stimulated (FS-) BEER was not significantly changed by PB-treatment. In chronic alcoholics (n = 15) U-BEER values above the upper limit (chi + 2 S D) obtained in healthy controls, were observed only when the time of sobriety was less than one week (n = 6). Values of FS-BEER in chronic alcoholics with increased basal alcohol oxidation rates were in the same range as those of healthy controls. In 5 out of the 6 alcoholics in whom the values were elevated on admission, BEER decreased significantly after withdrawal of alcohol for 2-4 weeks. Since FS-BEER was nearly identical in all conditions tested, the distinct changes in U-BEER are probably independent of changes in the activity of enzymes involved in alcohol oxidation. It is assumed that alcohol metabolism in man is mainly controlled by the rate of NADH reoxidation in the liver.
