Risperidone | C23H27FN4O2 - PubChem

Risperidone is a benzisoxazole derivative with antipsychotic property. Risperidone selectively antagonizes serotonin effects via cortical 5-HT2 receptor, and, to a lesser extent, competes with dopamine at the limbic dopamine D2 receptor. The antagonism leads to decreased psychotic effects, such as hallucinations and delusions.
