Can genetic testing help with drug dosages?
On One Hand: Genetic Testing and Drug EfficacyAccording to Medscape, genetic differences can affect the way the body interacts with certain drugs. In a review of several clinical studies, Medscape indicates that pharmacogenomics (genetically-based drug therapy) helps minimize the toxicity and maximize the efficacy of breast cancer treatment with Tamoxifen.On the Other: More Research NeededAccording to the Human Genome Project, pharmacogenomics still faces many hurdles including the technical challenge of finding gene variations, the lack of drug alternatives for different patients, the high cost of producing drug alternatives and the need for physician education in genetics.Bottom LinePharmacogenomics is not widespread in mainstream medicine yet.
