KaterR. M. H.: Increased Rate of Clearance of Drugs from the Circulation of Alcoholics, Am. J. Med. Sci.258: 35 (July) 1969. In a study of the plasma clearance rate of three drugs in alcoholics compared to a control group, warfarin half-life was 41.1 hours in the control group and 26.5 hours in the alcoholics. Increased drug clearance was attributed to alcoholic induction of endoplasmic reticulum of the liver.
