Aripiprazole in the acute treatment of male patients with schizophrenia: effectiveness, acceptability, and risks in the inner-city hospital setting

Aripiprazole, a novel atypical antipsychotic that acts as a partial agonist at the dopamine D(2) receptors, has been reported to be effective in the treatment of chronic schizophrenia. However, the risks and benefits of using aripiprazole in the acute hospital setting to treat severe psychotic disorders are unclear. This naturalistic study assessed the effectiveness of aripiprazole monotherapy in a group of actively psychotic male patients (n = 10) with schizophrenia who were admitted to an inner-city acute psychiatric unit. Most patients (n = 7) responded to aripiprazole treatment, which was well tolerated and significantly ameliorated psychotic symptoms after 2–3 weeks. Patients who responded to it could be safely discharged on aripiprazole monotherapy. Side effects observed were mostly mild and transient, and included extrapyramidal symptoms (n = 1) and neutropenia (n = 1). Aripiprazole also remarkably attenuated dyskinetic movements in 1 patient with severe tardive dyskinesia, thereby suggesting that it may be useful in the treatment of other disorders that are also associated with dopamine dysfunction. Results showed that aripiprazole can be safely and effectively employed in the hospital setting to treat severely psychotic patients with schizophrenia, but further studies are required to establish the full range of adverse reactions and therapeutic indications associated with its use.
