Lamotrigine as an add-on treatment for schizophrenia shows potential for improving symptoms, but evidence is not robust. More high-quality trials are needed to confirm its effectiveness and safety in clinical practice.

Area of Science:

  • Psychiatry
  • Clinical Pharmacology

Background:

  • Schizophrenia treatment is challenging for 20-30% of patients with treatment-resistant symptoms.
  • Preliminary studies suggest lamotrigine may benefit patients undergoing antipsychotic treatment.

Purpose of the Study:

  • To evaluate the efficacy of adjuvant lamotrigine in patients with schizophrenia and schizophrenia-like psychoses.

Main Methods:

  • Systematic review of clinical randomized trials comparing lamotrigine with placebo or other antipsychotic augmentation strategies.
  • Data extraction and analysis using random effects relative risk (RR) and weighted mean differences (WMD).

Main Results:

  • Lamotrigine did not significantly improve global response or overall mental state compared to placebo.

  • Significant reductions were observed in total, positive, and negative symptom scores on the PANSS.
  • Adverse effects were more frequent in the lamotrigine group, with nausea being a notable side effect.

    • Conclusions:

    • Current evidence for lamotrigine as an adjunctive treatment for schizophrenia is limited.
    • Large, well-designed, real-world randomized trials are necessary to establish its clinical utility.
