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. It is used for the treatment of schizophrenia and, especially, for psychosis-associated anxiety, due to its unique anxiolytic efficacy.
Cyamemazine differs from other phenothiazine neuroleptics in that aside from the usual profile of dopamine, α1-adrenergic, H1, and mACh receptor antagonism, it additionally produces potent blockade of several serotonin receptors, including 5-HT2A, 5-HT2C, and 5-HT7. These actions have been implicated in cyamemazine's anxiolytic effects (5-HT2C) and lack of extrapyramidal side effects (5-HT2A), and despite being classified as a typical antipsychotic, it actually behaves like an atypical antipsychotic.
