Application

Cyamemazine has been used as an internal standard and antipsychotic drug to spike plasma samples in mass spectrometry studies. It has also been used as an analytical standard in gas chromatography-tandem mass spectroscopic (GC-MS/MS) analysis.

Biochem/physiol Actions

Cyamemazine belongs to the class of phenothiazine drugs. It is known to treat severe depression, schizophrenia and bipolar disorder.
Cyamemazine is a potent antagonist of 5-HT2C and 5-HT3 receptors with antipsychotic and anxiolytic properties.

Cyamemazine (Tercian) is an antipsychotic drug with anxiolytic properties. Recently, an in vitro study showed that cyamemazine possesses high affinity for serotonin 5-HT(2A) receptors, which was fourfold higher than its affinity for dopamine D(2) receptors (Hameg et al. 2003). The

Cyamemazine (Tercian®) is an antipsychotic agent blocking central dopamine D(2) receptors, which induces few extrapyramidal adverse effects, due to a potent antagonistic action at serotonin 5-HT(2A) receptors. In vitro studies showed that the desmethyl metabolite of cyamemazine (N-desmethyl cyamemazine) has
