Abstract
- Risperidone is a relatively new antipsychotic agent. It is often referred to as 'atypical', because it has a mechanism of action that blocks post synaptic dopamine-2 and serotonin-2 receptors, it is associated with fewer extrapyramidal side effects, it is not yet associated with tardive dyskinesia, and it may have some efficacy on negative symptoms of schizophrenia. In despite of its 'atypical' nature, there are already more than 15 reports of risperidone-induced neuroleptic malignant syndrome. Only one case of risperidone-induced NMS was reported recently in Korea. We report one case of delayed risperidoneinduced neuroleptic malignant syndrome in young male patient and review the related articles.
