The American Journal of Psychiatry study concluded that the older, first-generation antipsychotic drug perphenazine was less expensive and as effective as newer medications such as AstraZeneca Plc's Seroquel and Eli Lilly and Co.'s Zyprexa.
Funded by the U.S. National Institutes of Health, the $42.6 million study suggests doctors should consider the use of older antipsychotics as a first choice for patients with schizophrenia, a group of psychotic diseases marked by delusions and hallucinations.
"There could be a very useful role -- from a clinical and cost-effectiveness standpoint -- for greater utilization of some older-generation medications," said Dr. Jeffrey Lieberman, a psychiatrist at Columbia University Medical Center and the study's lead author.
