Tiospirone(BMY-13,859), also sometimes calledtiaspironeortiosperone,is anatypical antipsychoticof theazapironeclass.[1]It was investigated as a treatment forschizophreniain the late 1980s and was found to have an effectiveness equivalent to those oftypical antipsychoticsinclinical trialsbut without causingextrapyramidalside 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 morepotentand moreselectivein comparison and was commercialized instead.[6]
