Background: The term antipsychotic polypharmacy (APP) refers to the concurrent use of two or more antipsychotic drugs in schizophrenia. The aim of this study was to investigate the range of APP in schizophrenic patients discharged from psychiatric units in Poland, and to determine its demographical and clinical correlates. Methods: Data on the pharmacological treatment of 207 patients with a diagnosis of schizophrenia, discharged from six psychiatric hospitals from September-December 2011 were recorded by experienced psychiatrists. Clinical and demographical information was obtained on each patient. The severity of symptoms at admission, and their improvement during hospitalization were assessed using the Clinical Global Impression Scale. Results: At discharge, 52.7% of the patients were prescribed one, 42.5% two and 4.8% three antipsychotic drugs (AP). When two AP were applied, it was usually a combination of two second generation antipsychotics (SGA) (46%), or of both first generation antipsychotics (FGA) and SGA (48%). The SGA's olanzapine and risperidone were those most commonly prescribed. Patients treated with two or more AP had a higher number of previous hospitalizations than patients receiving antipsychotic monotherapy. Mood stabilizers were prescribed for nearly one third of the patients, while antidepressants and benzodiazepines were prescribed for fewer than 10%. Conclusions: The prevalence of polypharmacy in Poland is similar to that reported in other countries. This may suggest that, in a substantial proportion of schizophrenic patients clinical response to the antipsychotic monotherapy is unsatisfactory. Further studies focusing on the efficacy and safety of strategies in the treatment of patients with schizophrenia not responding to antipsychotic monotherapy are necessary.
