Prescribing patterns of neuroactive drugs in 98 schizophrenic patients

Abstract

Ninety-eight schizophrenic outpatients receiving pharmacotherapy were surveyed on two census days, 18 months apart. From this study sample it was found that, as recently as 1987, 18% of the patients were prescribed three classes of neuroactive drugs--16% two antipsychotic drugs simultaneously. Of antipsychotics receivers, 44% were prescribed anticholinergics, 3% antidepressants, and 4% benzodiazepines. Between census days, a significant shift from use of oral antipsychotics to the depot form of administration occurred, while polypharmacy frequency remained unchanged. An analysis of the data will provide guidelines for rendering a more rational pharmacological treatment.
