Objective: Aripiprazole, a synthetic compound, obtained by chemical modification of the structure of quinolinone is considered as an atypical antipsychotic drug. The present review is an attempt to summarize the updated information related to reported chemistry and pharmacology of Aripiprazole. Development: Aripiprazole, under development by Otsuka Pharmaceutical, was approved by the U.S. Food and Drug Administration (USFDA) by the end of 2002 with an aim to treat patients with schizophrenia.

The major side effects include headache, agitation, akithesia, anxiety, tachycardia, insomnia, postural hypotension, constipation, vomiting, dizziness, nervousness and somnolence. Conclusion: The present article embarks the available information on Aripiprazole with emphasis on its clinical pharmacology, mechanism of action, pharmacokinetics, pharmacodynamics, metabolism and clinical trials.
