Pharmacogenomics studies how inherited genes affect how the human body processes and responds to medications, which causes these medications to become more or less effective and more or less toxic.
A drug can act differently in two patients, even if it was given for the same condition. For example, some patients may experience significant side effects with a given drug, while others may not, even when receiving comparable doses of the drug. Pharmacogenomics offers important benefits such as:

Improving patient safety:
Severe drug reactions cause numerous hospitalizations annually. Pharmacogenomics can prevent them by identifying patients at risk.
Improving healthcare costs and efficiency:
Pharmacogenomics can help find the right drugs and doses faster.

PROBLEM:

Pharmacogenetics is the area of genetics responsible for studying the impacts of genetic variability in the population on the effects of drug therapy, with the main purpose of minimizing adverse effects and optimizing therapeutic effects. In the United States, for example, more than two million people are hospitalized and at least 100,000 die each year as a result of non-response or adverse drug reactions. However, there are some challenges in the development and practical use of pharmacogenomics. Tests are expensive and not widely available, and health plans often do not cover the costs of available tests.

SOLUTION:

Pharmacogenetic tests can significantly change the relationship between patients and the drug, the doctor and the pharmacist. With the help of pharmacogenetics, the specialist will be able to be more confident and assertive when prescribing the appropriate medication and the correct dose since he will have important information about the patient’s genetic profile.
