Lurasidone is an N-arylpiperazine that is (3aR,4S,7R,7aS)-2-{[(1R,2R)-2-(piperazin-1-ylmethyl)cyclohexyl]methyl}hexahydro-1H-4,7-methanoisoindole-1,3(2H)-dione in which position N4 of the piperazine ring is substituted by a 1,2-benzothiazol-3-yl group. Lurasidone is used (generally as the hydrochloride salt) as an atypical antipsychotic for the treatment of schizophrenia. It has a role as an adrenergic antagonist, a serotonergic antagonist, a dopaminergic antagonist and a second generation antipsychotic. It is a dicarboximide, a bridged compound, a N-arylpiperazine and a 1,2-benzisothiazole. It is functionally related to a maleimide. It is a conjugate base of a lurasidone(1+).
