Cytochrome P450 2D6 (CYP 450 2D6) Genotype and Flecainide Efficacy

April 4, 2011 updated by: Assaf-Harofeh Medical Center

The Use of CYP 450 2D6 Genotype as a Predictor of Flecainide Efficacy in the Treatment of Patients With Atrial Fibrillation

The determination of the 2D6 genotype will enable us to determine the way flecainide is metabolized by the liver. Some individuals are poor metabolizers and some individuals are extensive metabolizers of the drug. This will also determine which patients will benefit from the drug.

Detailed Description

Pharmacogenetics is the study of genetic variations on drug metabolizing enzymes and transporters. Pharmacogenetics is one of the first clinical applications of the Human Genome Project. Pharmacogenomics is the study of the role of interindividual genomics variability on drug response, efficacy, and metabolism. It correlates the effects of the entire expressed genome to the clinical usefulness and toxicity of a drug. Pharmacogenomics has the potential to change the way patients' therapy is optimized, allowing an era of "personalized medicine" in which patients will be divided into groups based on genetic markers that treatment outcomes.
