A relatively simple and rapid method has been developed to induce tolerance to and dependence on alcohol in mice. Alternating intraperitoneal injections of metabolically stable tert-butanol and ethanol for 4 consecutive days resulted in a physical dependence on alcohol, which was quantified by the latency and ED50 of picrotoxin-induced CNS hyperexcitability--myoclonic and tonic seizures and mortality--during the withdrawal period. The data indicate that alcohol-dependent animals in the withdrawal period are more susceptible than alcohol-naive controls to picrotoxin. Withdrawal hyperexcitability can be quantified by the ED50 of picrotoxin.
