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.
