Review Article


Pharmacologic management strategies for schizophrenia, a relatively common psychotic disorder, include the use of typical and atypical antipsychotic drugs. In general, typical (or conventional) antipsychotics have a proven track record in effectively managing the positive symptoms of schizophrenia but sometimes lack efficacy in treating negative symptoms. The conventional agents are also associated with adverse neurologic effects such as extrapyramidal symptoms (EPS). The development of atypical antipsychotics has partly ameliorated the issue of EPS induced by typical antipsychotics. However, several of these atypical antipsychotic agents have been associated with adverse metabolic effects, including weight gain, dyslipidemia, and increased serum glucose levels. Paliperidone (9-hydroxy-riperidone) extended-release (ER) is an atypical antipsychotic indicated for the treatment of schizophrenia which utilizes a patented oral osmotic system technology that provides constant drug delivery over the course of the day. The efficacy and safety of paliperidone ER in patients with schizophrenia have been established. This review focuses on the metabolic safety of paliperidone ER in patients with schizophrenia. Clinical trials have demonstrated a lack of significant change in lipid profiles with paliperidone ER; furthermore, reported incidences of glucose-related adverse events in clinical trials were very low and similar to those seen with placebo. While dose-related increases in bodyweight of 1–2 kg have been observed with paliperidone ER, there are few reports of clinically relevant increases in bodyweight during treatment. Placebo-controlled trials indicate that the risk of developing metabolic disorders with paliperidone ER is low and similar to that seen with placebo. Furthermore, the ER formulation of paliperidone may offer potential advantages over atypical antipsychotics such as risperidone, particularly with regard to side effects and compliance, but comparative studies are needed.
