Cyamemazine (Tercian), also known as cyamepromazine, is a typical antipsychotic drug of the phenothiazine class which was introduced by Theraplix in France in 1972 and later in Portugal as well.[1][2][3][4] It is used for the treatment of schizophrenia and, especially, for psychosis-associated anxiety, due to its unique anxiolytic efficacy.[5][6]

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, it actually behaves like an atypical antipsychotic.[11]
