title: [Effect of repeated haloperidol and apomorphine administration on the development of tolerance for catalepsy and dopamine receptor hypersensitivity in mice].
abstract: It has been shown in experiments on mice that repeated administration of haloperidol (20 days) in doses of 0.1 and 5.0 mg/kg provoked an increase in the tolerance to the drug cataleptic effect. When administered in a higher dose (5.0 mg/kg), the drug increased 3H-spiroperidol binding with the striatal membranes 72 hours after withdrawal. Repeated administration of apomorphine in doses of 0.1 and 1 mg/kg combined with haloperidol antagonized the development of the tolerance and reduced the hypersensitivity of dopamine receptors, observed after withdrawal of haloperidol in a dose of 5.0 mg/kg. The low apomorphine dose also potentiated the haloperidol-induced catalepsy.
