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.

Animal and human pharmacological studies indicate that the antipsychotic action of cyamemazine results from blockade of dopamine D(2) receptors, its anxiolytic properties from serotonin 5-HT(2C) receptor antagonism and the low incidence of extrapyramidal side effects from a potent 5-HT(2A) receptor

The antipsychotic and anxiolytic phenothiazine, cyamemazine, was investigated for its effects on the hERG (human ether-à-go-go related gene) channel expressed in HEK 293 cells and on native INa, ICa, Ito, Isus, or IK1 of human atrial myocytes. Moreover, cyamemazine and

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
