Conclusion of this study

This study, the first to our knowledge that examines the efficacy of a glutamatergic agent in the treatment of trichotillomania, found that N-acetylcysteine demonstrated statistically significant reductions in trichotillomania symptoms. No adverse events occurred in the N-acetylcysteine group, and N-acetylcysteine was well tolerated. Pharmacologic modulation of the glutamate system may prove to be useful in the control of a range of compulsive behaviors.
