objective: the current study was performed to evaluate the cognitive improvements of the chronic schizophrenic patients treated with risperidone in comparison with those treated with haloperidol according to wisconsin card sorting test (wcst). methods: in a double blind clinical trial, 65 patients with a diagnosis of chronic schizophrenia were randomly allocated into two groups. they received a...

1. Haloperidol and reduced haloperidol plasma concentrations were measured in thirteen stable schizophrenic patients that received both oral haloperidol and haloperidol decanoate. 2. Significant correlations between reduced haloperidol/haloperidol ratios from oral haloperidol and haloperidol decanoate occurred at week two and week 16, respectively. 3. The formation of RH was consistent during h...

Objective(s): Dopamine plays an important role in cognitive functions. Inhibition of the dopamine-degrading enzyme catechol-O-methyltransferase (COMT) may have beneficial effects. Our aim was to assess the effect of COMT inhibitor tolcapone (TCP) on learning and memory in naïve and haloperidol-challenged rats.Materials and Methods: Male ...

introduction: a number of research studies have shown that the new generation of neuroleptic medications can more effectively contribute to treating negative symptoms of schizophrenia compared with the first generation by influence cognitive functioning. the present study examined the therapeutic effectiveness of manufactured risperidone and haloperidol in iran on treating the negative symptoms...

The neurotoxic side effects observed for the neuroleptic agent haloperidol have been associated with its pyridinium metabolite. In a previous study, a silicon analog of haloperidol (sila-haloperidol) was synthesized, which contains a silicon atom instead of the carbon atom in the 4-position of the piperidine ring. In the present study, the phase I metabolism of sila-haloperidol and haloperidol ...
