title: Ziprasidone suppresses olanzapine-induced increases in ingestive behaviour in the rat.
abstract: Many atypical antipsychotic drugs, such as olanzapine, induce significant weight gain. However, ziprasidone produces minimal weight gain, the mechanism of which remains unclear. The aim of the present study was to investigate whether ziprasidone would reduce the acute effect of olanzapine on feeding behaviour. The results suggest that ziprasidone suppresses the significant increases in food intake produced by olanzapine, indicating that it has an intrinsic protective mechanism against drug-induced increases in food intake.
