In therapeutic activity against a disease, the doctor’s initial observation is the interindividual variability of the response, which is intrinsically linked to the genetic characteristics of the subject and modulated by physiological, pathological and environmental factors.

Pharmacogenetics is the science that allows the genetic basis of interindividual differences in the response to drugs to be identified. In this sense, pharmacogenetics provides at least one way to make medical prescriptions without the usual empiricism and move towards more personalised therapy.
