The effectiveness of cross-tapering switching to ziprasidone in patients with schizophrenia or schizoaffective disorder.

ABSTRACT:

Objective

Switching antipsychotics is one useful therapeutic option when the treatment of schizophrenia encounters suboptimal efficacy and intolerability issues. This study aimed to investigate the efficacy and tolerability of cross-tapering switching to ziprasidone from other antipsychotics.
