Drugs known as SSRIs—selective serotonin reuptake inhibitors—work by stopping serotonin from being reused by binding to the serotonin transporter (SERT) and blocking serotonin transport.

What are the two genes involved in metabolizing antidepressants?

Major candidates of interest for pharmacogenetic research are the genes encoding enzymes participating in the metabolism of antidepressants. These are primarily in the cytochrome (CYP) P450 family, and include CYP1A2, CYP2C19, CYP2D6 and CYP3A4.
