Cyamemazine differs from other phenothiazine neuroleptics in that aside from the usual profile of dopamine, α1-adrenergic, H1, and mACh receptor antagonism,[7] it additionally produces potent blockade of several serotonin receptors, including 5-HT2A, 5-HT2C, and 5-HT7.[7][8][9][10] These actions have been implicated in cyamemazine's anxiolytic effects (5-HT2C) and lack of extrapyramidal side effects (5-HT2A),[7][8] and despite being classified as a typical antipsychotic, it actually behaves like an atypical antipsychotic.[11]
