Tiospirone (BMY-13,859), also sometimes called tiaspirone or tiosperone, is an atypical antipsychotic of the azapirone class.[1] It was investigated as a treatment for schizophrenia in the late 1980s and was found to have an effectiveness equivalent to those of typical antipsychotics in clinical trials but without causing extrapyramidal side effects.[2][3][4][5] However, development was halted and it was not marketed. Perospirone, another azapirone derivative with antipsychotic properties, was synthesized and assayed several years after tiospirone.[6] It was found to be both more potent and more selective in comparison and was commercialized instead.[6]
Tiospirone acts as a 5-HT1A receptor partial agonist, 5-HT2A, 5-HT2C, and 5-HT7 receptor inverse agonist, and D2, D4, and α1-adrenergic receptor antagonist.[7][8][9][10][11][12]
