Objective: Combined antipsychotic treatment is frequently used in clinical practice either to improve the symptom control or to reduce the severity of side effects. The expected benefits by combining different antipsychotics include active cross-titration and co-utilization of different administration routes of the therapeutic agents. However, except the add-on therapies to clozapine, there is no objective evidence implying the superiority of combined therapy over monotherapy. Furthermore, there are a number of published case reports of significant side effects accompanying combined antipsychotic usage such as extrapyramidal and metabolic symptoms, seizures, and electrocardiographic abnormalities. It is also argued that switching into a new therapeutic agent might be more beneficial than augmenting the ongoing medication by polypharmacy. Here, we studied on a group of hospitalized schizophrenia patients in a training and research hospital in Turkey whether the Positive and Negative Symptom Scale (PANSS) scores differ between the patients under monotherapy and combined therapy.
