Evaluating the Clinical Utility of Genetic Testing in Guiding Medication Selection

Abstract

The study of genetic factors influencing medication response variability is known as pharmacogenetics. Pre-emptive genotyping of germline pharmacogenetic variations by personalised medicine programs indicates a growing interest in using clinical pharmacogenetic testing. Pharmacogenomics, a flourishing branch of pharmacy, establishes to initiate the use of individual’s personalized genetic information’s to guide treatment therapy. Pharmacogenetics reveals that SNPs in candidate genes are directly associated with efficacy and/or toxicity of prescribed drugs However, obstacles like as cost, integration into clinical practice, and the need for more education among healthcare personnel remain. Pharmacogenomics has the potential to significantly improve personalised medicine as it becomes more widely used, which will increase patient care.
