The effects of carbamazepine on two animal models of depression.
Some clinical reports on antimanic, antidepressant and prophylactic effects of carbamazepine (CBZ) in manic-depressive illness have appeared since its initial use as an anticonvulsant drug. The present report deals with the effects of CBZ on two animal models of depression, namely the potentiation of amphetamine-induced anorexia, and the behavioral despair model. Carbamazepine (10, 20 or 40 mg/kg) neither modified the methamphetamine anorectic effect, nor induced anorexia when administered alone. Subacute and chronic administration of imipramine (4 or 15 mg/kg) decreased immobility of rats in the behavioral despair model. Subacute and chronic administration of CBZ (40 mg/kg) also decreased immobility, whereas the dose of 10 mg/kg CBZ was effective only after chronic treatment. It was concluded that CBZ is similar to atypical antidepressants, since it did not potentiate the amphetamine-induced behavioral effect, but did have an effect on the behavioral despair model of depression.
