Some behavioural effects of carbamazepine - comparison with haloperidol

The experiments presented in this paper aimed to investigate the influence of atypical antiepileptic drug carbamazepine (CBZ, CAS 298-46-4) classified also as normothymic drug on spatial memory in Morris water maze test and anxiolytic effect in two-compartment exploratory test in rats.

Description
Summary:The experiments presented in this paper aimed to investigate the influence of atypical antiepileptic drug carbamazepine (CBZ, CAS 298-46-4) classified also as normothymic drug on spatial memory in Morris water maze test and anxiolytic effect in two-compartment exploratory test in rats. The study also investigated the probably occurring side effects (measuring cataleptic activity and motor coordination) following single and chronic administration of CBZ compared to haloperidol (HAL, CAS 52-86-8), a conventional antipsychotic. All the tests were carried out on male Wistar rats. CBZ 30 mg/kg was administered orally 60 min before the tests and HAL 0.15 mg/kg was administered orally 60 min before the tests. In the Morris test memory improvement only after chronic administration of CBZ on the 7 and 14 day of treatment was observed, whereas after 14 days of HAL treatment spatial memory impairment was noted. In the two-compartment exploratory test 30 mg/kg of CBZ had an anxiolytic effect after 7 and 14 days of treatment, whereas HAL did not show anxiolytic effect after single and chronic treatment. CBZ did not induce catalepsy after single as well as chronic administration. HAL evoked a strong cataleptic effect both after acute and chronic treatment. CBZ had no impact on motor coordination in the chimney test and HAL disturbed motor coordination in rats after single as well as chronic administration. CBZ may be an useful normothymic drug using in bipolar affective disorder treatment with co-occurred anxiety and cognitive deficits. The lack of significant side effects of CBZ may be an alternative way of treatment in comparison with older drugs, such as lithium carbonate.
