Cytochrome P450 2C19 (encoded by the gene CYP2C19) is a liver enzyme that participates in the activation of the anticoagulant clopidogrel (Plavix) and metabolism of other drugs, such as citalopram. As a result, Clopidrigrel may be less effective in altering platelet activity in those people, who may remain at risk for heart attack, stroke, and cardiovascular death.
