  • Title: Attenuation of ethanol metabolism by supplementary carnitine in rats.
    Author: Sachan DS, Berger R.
    Journal: Alcohol; 1987; 4(1):31-5. PubMed ID: 3828061.
    Abstract:
    The purpose of this study was to examine the effect of supplementary D,L-carnitine on blood-ethanol levels and ascertain if the effect was a result of altered absorption or metabolism of ethanol. Mature male Sprague-Dawley rats were fed Purina Rat Chow as such or supplemented with various levels of D,L-carnitine. First it was established that supplementing carnitine at 1% (w/w) level produced steady state concentrations of carnitine in blood after 3 days of feeding. When a single dose of ethanol was given orally after 5 days of carnitine supplementation, the blood levels of ethanol remained significantly elevated for 2-8 hours in the carnitine supplemented animals. Time course of blood-ethanol concentrations revealed that carnitine did not affect the rates of ethanol absorption and therefore, the effect must be due to the attenuation of ethanol clearance from the blood.
