**5. Conclusions**

The discipline of pharmacogenomics (PGX) has rapidly developed, and its application to patient care is continuing to unfold. It is acknowledged that pharmacogenetics may not be equally important for every drug. Genetic factors influencing drugs' pharmacokinetic phases are centered on drug metabolism and transportation. Pharmacogenetic testing investigations should be promoted in sectors where there is a high probability of a clinically meaningful impact on clinical practice.
