History

Over the past sixty years, many studies have suggested that a significant portion of drug response variability is determined by genetics, along with diet, health status, exposure to the environment, and concurrent treatment [3].
Drug treatment must be tailored to individual needs with a relatively predictable outcome across a variety of geographically and ethnically diverse populations. Starting in the early 1950s, these findings of highly variable drug reactions led to a new scientific discipline called pharmacogenomics, which combines genetics, biochemistry, and pharmacology [4].
The field of pharmacogenomics was the result of molecular medicine advances, aiming to understand the molecular mechanisms behind drug response. Personalized medicine is the name given to this application of research.
Personalized medicine has yet to be fully understood by the average patient, but it will eventually affect the entire health care system. Personalized medicine has come a long way since the human genome was mapped in 2003, especially in terms of discovery and product creation. Preventive, organized, and validated personalized medicine is a system for effective and efficient health care. In order to make the best care decisions possible, patients and doctors need access to a network of electronic health records that connects both clinical and molecular data. Personalized medicine compensates for genetic susceptibilities by integrating lifestyle choices and health maintenance.
