ABSTRACT

Atypical antipsychotics generally have a lower propensity for extrapyramidal side-effects (EPSE), hyperprolactinaemia and tardive dyskinesia than that associated with typical antipsychotics but may still produce troublesome side-effects, such as weight gain, cardiac rhythm changes and impaired glucose tolerance. Aripiprazole is a new atypical antipsychotic with a unique receptor binding profile that combines partial agonist activity at D2 and 5HT1A receptors with potent antagonism at 5HT2A receptors. Clinical studies in acute schizophrenic relapse, chronic schizophrenia and acute mania show it is robustly more effective than placebo. Once-daily aripiprazole 15-30 mg is as effective as haloperidol 10 mg/day and risperidone 6 mg/day in short-term treatment of schizophrenia and more effective than haloperidol 7-10 mg/day in maintenance of response in chronic schizophrenia. Aripiprazole appears to be well tolerated, with most studies suggesting a frequency of adverse effects similar to placebo. Aripiprazole seems not to cause significant EPSE, hyperprolactinaemia, excessive weight gain or cardiac rhythm disturbance. Limited data suggest that aripiprazole is not associated with impaired glucose tolerance.
