What is the main focus of pharmacogenomics?

The main focus of pharmacogenomics is to examine individual genetic responses to drugs. This field integrates pharmacology and genomics to understand how an individual’s genetic makeup affects their response to medications. By studying variations in genes that influence drug metabolism, effectiveness, and safety, pharmacogenomics aims to personalize medicine, optimizing drug therapy for better efficacy and minimal adverse effects.

This emphasis on individual genetic profiles allows for tailored treatment plans, which can improve patient outcomes significantly. For example, certain genetic variants can predict a patient's likelihood of experiencing adverse drug reactions or their efficiency in metabolizing a specific medication. Such insights can ultimately lead to more effective dosing strategies and the development of safer drugs.

While the other options touch upon important aspects of pharmaceutical science, they do not capture the core intent of pharmacogenomics as accurately as the understanding of individual genetic responses to drugs. Developing new drugs, understanding drug actions, and regulating pharmaceutical companies are relevant fields but do not specifically address the personalized approach that pharmacogenomics emphasizes.
