Influence of haloperidol and clozapine on some behavioral effects in rats.

The experiments presented in the following paper aimed to investigate the influence of atypical antipsychotic clozapine (CLO, CAS 578-21-0) classified also as normothymic drug on spatial memory in rats in Morris water maze test. The study also investigated the probably occurring side effects (measuring cataleptic activity and motor coordination) following single and chronic administration of CLO compared to haloperidol ( HAL, CAS 52-86-8), a conventional antipsychotic. All the tests were carried out on male Wistar rats. CLO 10 mg/kg was administered orally 30 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 CLO on the 7th and 14th day of treatment was observed, whereas after 14 days of HAL treatment spatial memory impairment was noted. CLO did not induce catalepsy after single as well as chronic administration, but administrated chronically induced a tendency for its occurrence. HAL evoked a strong cataleptic effect both after acute and chronic treatment. CLO had no impact on motor coordination in the chimney test except on day 14 when statistically significant impairments were observed. HAL disturbed motor coordination in rats after single as well as chronic administration. The wide and unique spectrum of receptor activity of CLO in comparison with HAL as well as some neurotransmitters' interactions may explain its usefulness in long-term therapy of bipolar affective disorder and schizoaffective disorder with co-occurred cognitive deficits.[1]
