Definition of Pharmacogenetics

Pharmacogenetics is a branch of pharmacology which deals with the study of responses people have for different drugs. The people respond differently to the drugs due to the fact that their genetic material is different from one another. Other factors that influence the medication response include the diet, environment and the health but the genes are the strongest indicator that tells how a drug would be processed.


The drugs start metabolizing in the body as soon as they enter the bloodstream. The metabolism is totally dependent upon the genes that control the working of drug-processing enzymes. After getting metabolized, the drugs leave the body through the process of elimination.
