Additional Information
Barbiturates are sedative hypnotics. If overdosage occurs, coma and death may result. The toxic or lethal blood level varies with many factors and cannot be stated with certainty. In presence of alcohol or other depressant drugs, the lethal concentrations may be lower. The long-acting drugs are metabolized slowly and depend primarily on the kidney for elimination; the short- and intermediate-acting drugs are metabolized primarily by the liver and are much less dependent on the kidney for excretion. Except for barbital, all barbiturates are primarily transformed by the liver. Only barbital is dependent mainly on renal excretion for termination of its pharmacological action.
