Risperidone in the treatment of psychoses in the elderly: a case report series

Risperidone is one of the newer atypical antipsychotic agents, which combines potent serotonin and dopamine receptor antagonism. It shows efficacy against the positive and negative symptoms of schizophrenic psychoses and other psychotic conditions, and has a low propensity to cause extrapyramidal side effects. The aim of these case reports in elderly patients is to provide the benefit of personal experience with risperidone to the body of published literature and to demonstrate the types of patients that may benefit from treatment. These cases were compiled retrospectively from data collected on referral and during routine hospital appointments. This series covers four main areas of concern when treating the elderly: low-maintenance dosing minimising the likelihood of adverse events; successful treatment of patients previously uncontrolled and experiencing side effects with other antipsychotics; the possibility of intermittent rather than continuous treatment; and the benefits to patients, carers and the health services. At low doses, risperidone is an effective and well-tolerated treatment for psychoses in elderly patients that improves the quality of life for both patients and their caregivers.
