Paliperidone Extended-release Tablets: A New Atypical Antipsychotic
By Robert H. Howland, MD
Schizophrenia is a severe, chronic, and disabling illness. The overall effectiveness of available antipsychotic drugs is limited. Many patients do not respond to available drugs, or they experience residual symptoms despite adequate treatment. Some patients respond to medication but experience intolerable side effects and stop treatment. For these reasons, new drug therapies are always needed. Although a new drug may not necessarily be more effective on average compared with available drugs, for certain patients it may be relatively more effective or better tolerated. In this article, the clinical use of the new atypical antipsychotic drug paliperidone extended-release (pal-ER, Invega) is reviewed.
