What is pharmacogenetics?

Pharmacogenetics examines how a person’s genetic makeup shapes their response to medicines. It explains why some individuals achieve better efficacy or experience more adverse effects because gene variations influence drug targets, how drugs are metabolized, and how they are transported in the body. This focus on genetic factors that alter drug response is exactly what the description “genetic influences on drug response” conveys. For context, genetic differences in enzymes like CYP450 can make someone a fast or slow metabolizer, changing drug levels and the risk of toxicity. Variants in drug targets or transporters can also affect how well a drug works or how it’s distributed. In contrast, describing metabolism in the liver touches on pharmacokinetics in a non-genetic sense, and legal regulation of patents or the process of formulating a drug belong to drug development and policy or pharmaceutical science, not pharmacogenetics.
