As very limited data are available on the clinical use of antioxidants for mania, we report here results from a post hoc and exploratory subgroup analysis of a randomized, placebo-controlled trial of N-acetyl cysteine (NAC).
Methods: This was a placebo-controlled, randomized, clinical trial assessing the effect of NAC over 24 weeks in mania or hypomania. Symptomatic and functional outcomes were collected over the study period.
Results: Fifteen participants were available for this report; two participants in each group failed to complete all assessments. Within-group analyses pointed to an improvement in the NAC group on manic symptoms and worsening in the placebo group on depressive symptoms at endpoint.
Conclusions: Although the sample size was small, these results indicated within-group efficacy for this glutathione precursor as compared to placebo. Future trials specifically designed to demonstrate the efficacy of NAC in mania are needed.
