Effect of acute alcohol intoxication on the metabolism and plasma kinetics of chlordiazepoxide. 1979

B Whiting, and J R Lawrence, and G G Skellern, and J Meier

1. The metabolism and plasma kinetics of chlordiazepoxide have been determined in a group of volunteers and in a group of patients with acute alcohol intoxication. 2. Using the SAAM 26 non-linear least squares fitting programme, all chlordiazepoxide plasma concentration v time data following oral administration could be analysed in terms of a one-compartment open model with metabolic conversion of chlordiazepoxide to desmethylchlordiazepoxide. 3. Acutely intoxicated patients showed a prolonged elimination of chlordiazepoxide and a reduced clearance when compared with alcohol-free volunteers. The elimination of desmethylchlordiazepoxide, on the other hand, appeared to be faster in the alcoholics. 4. Alcohol exerts significant effects on the metabolism of chlordiazepoxide in acutely intoxicated patients.
