Gradual vs. wait-and-gradual discontinuation in antipsychotic switching: A meta-analysis.

To address whether wait discontinuation (i.e., introducing the new antipsychotic while maintaining the first for a period before initiating its discontinuation) is superior to non-wait discontinuation (i.e., initiating the first antipsychotic's discontinuation when introducing the new antipsychotic) in antipsychotic switching, we conducted a meta-analysis of randomized controlled trials comparing gradual vs. wait-and-gradual antipsychotic discontinuation in patients with schizophrenia. The meta-analysis of 5 studies (n=410) demonstrated no significant differences in any clinical outcomes, including study discontinuation, psychopathology, extrapyramidal symptoms, and treatment-emergent adverse events, between the two groups. These findings indicate either strategy can be used in clinical practice.
