Evaluation of dopamine D2/D3 and serotonin 5-HT2A receptor occupancy for a novel antipsychotic, lurasidone, in conscious common marmosets using small-animal positron emission tomography

Lurasidone is a novel antipsychotic drug with potent binding affinity for dopamine D2 and serotonin (5-hydroxytryptamine, 5-HT)2A, 5-HT7, and 5-HT1A receptors. Previous pharmacological studies have revealed that lurasidone exhibits a preferable profile (potent antipsychotic activity and lower incidence of catalepsy) to other antipsychotic drugs, although the contribution of receptor subtypes to this profile remains unclear. To compare target...
