Pharmacogenomics is the branch of pharmaceutics
which deals with the influence of genetic variation on drug
response in patients by correlating gene expression or single-nucleotide
polymorphisms with a drug's efficacy or toxicity. By doing so,
pharmacogenomics aims to develop rational means to optimise
drug therapy, with respect to the patients' genotype, to ensure
maximum efficacy with minimal adverse effects. Such approaches
promise the advent of "personalized Medicine", in
which drugs and drug combinations are optimized for each individual's
unique genetic makeup.
