Oral antipsychotic update: a brief review of new and investigational agents for the treatment of schizophrenia.

Antipsychotics are the mainstay of treatment for patients with schizophrenia. However, these medications only work if they are taken and perhaps work best if they are taken for longer periods of time than seen in typical research trials. Here we explore the idea of "time as drug" by reviewing the data showing the potential benefits of long-term antipsychotic use. We also discuss the utility of depot antipsychotic formulations for improving the chances of attaining long-term therapeutic results.
