title: Tolerance development to cadmium-induced alteration of drug action.
abstract: Cadmium administration potentiates the duration of hexobarbital-induced hypnosis and inhibits the rate of hepatic microsomal metabolism of this drug in the male rat. The threshold dose of cadmium required to produce these alterations in drug action is 0.84 mg Ck/kg. If subthreshold doses of cadmium (0.21 or 0.42 mg Cd/kg) are administered prior to the 0.84 mg Cd/kg dose, the cadmium-induced alterations in drug action are no longer observed.
