Notes: Risperidone-d5 is intended for use as an internal standard for the quantification of risperidone (Item No. 13629) by GC- or LC-MS. Risperidone is an atypical antipsychotic that binds to dopamine D2 receptors (Ki = 3 nM) and the serotonin (5-HT) receptor subtype 5-HT2A (Ki = 0.12 nM).{39942,21347} It also binds to dopamine D4, α1- and α2-adrenergic, 5-HT1C, 5-HT1D, and histamine H1 receptors (Kis = 7, 0.81, 7.3, 47, 52, and 2.1 nM, respectively). Risperidone (0.1 mg/kg per day, i.p.) attenuates deficits in prepulse inhibition of the acoustic startle response, but not deficits in social interaction, in a rat neonatal ventral hippocampal lesion model of schizophrenia.{39941} Formulations containing risperidone have been used in the treatment of schizophrenia and bipolar disorder.
