Lamotrigine as Add-On Therapy in Schizophrenia

Abstract

: Results from these 2 studies do not support the use of lamotrigine as an adjunct to atypical antipsychotics in patients with refractory psychosis. It is unclear why positive results from previous lamotrigine trials were not replicated. The positive effect of lamotrigine on cognition in one trial, while of uncertain significance, may merit further study.
