Description

Cyamemazine (Tercian), also known as cyamepromazine, is a typical antipsychotic drug of the phenothiazine class used primarily in the treatment of schizophrenia and psychosis-associated anxiety. Cyamemazine actually behaves like an atypical antipsychotic, due to its potent anxiolytic effects and lack of extrapyramidal side effects. Cyamemazine is used for the treatment of chronic psychotic states, anxiety, major depression.

In Vitro Use Guide
Binding to receptors was carried out using radioligand binding assay. Suspension of cells, expressing the receptor was incubated with cyamemazine and a reference radioligand. At the end of incubation period, membranes or cells were rapidly filtered under vacuum conditions through glass fiber filters. Bound radioactivity was measured with a scintillation counter. Each competition concentration-response curve was determined in duplicated using cyamemazine concentration spanning from 0.03 nM to 30-100 uM
