Background

Risperidone is an atypical antipsychotic that binds to dopamine D₂ receptors (K_i = 3 nM) and the serotonin (5-HT) receptor subtype 5-HT_2A (K_i = 0.12 nM).^1,2 It also binds to dopamine D₄, α₁- and α₂-adrenergic, 5-HT_1C, 5-HT_1D, and histamine H₁ receptors (K_is = 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.³ Formulations containing risperidone have been used in the treatment of schizophrenia and bipolar disorder.
