Pharmacogenomics enables medical practitioners to prescribe medicines with accurate information and provide improved medical care using patients' genetic data.
FREMONT, CA: Health care providers increasingly focus on providing treatments based on patient needs. PGx (Pharmacogenomics) has the potential to play a vital role in promoting the safe and effective prescribing of medications by using a patient's genetic information to predict medication response and promote safe and effective prescribing practices. In some cases, standard drug doses are toxic if the individual carries a variant of a gene responsible for their inability to metabolize it at a normal rate, for example, due to genetics. The PGx data can empower a provider to prescribe a lower drug dose to reduce the patient's risk of experiencing severe, unwanted side effects or to choose an alternative medication that may be more appropriate for the patient. A genetic test can also provide important information about whether a drug target is present, allowing prescribers to select the most appropriate treatment for the patient based on the likely success rate of the drug.

PGx has the potential to revolutionize how care is delivered and improve the outcomes for patients, but many challenges remain along the way to making this promise a reality.Researchers have identified genes as being associated with certain drugs in early PGx studies. The complexity of understanding how to apply this knowledge, and apply it most consistently and effectively, was quickly apparent, as figuring this out took considerable time.
Precision Genetics' successful implementation
A comprehensive medication therapy management and prescription cost optimization program that includes PGx testing for high-risk patients has been developed by Precision Genetics to address these challenges. Electronically delivered PGx results and related recommendations to patient charts for clinicians to consult.
How can PGx be made the standard of care?
Precision Genetics, for example, offers PGx testing along with other targeted efforts, such as a specialty clinic at a large academic medical institution. Medical practitioners must address many hurdles before applying clinical PGx widely. PGx tests and results will be more widely available as more people will have access to them, leading to greater adoption and use of PGx data, which will encourage payers to cover such testing more readily. The availability and accuracy of PGx testing depend on reliable testing methods. With PGx, patients may avoid harmful medication side effects, avoid ineffective treatment, and design regimens for maximum performance. Data from PGx is also likely to lead to a reduction in overall healthcare costs by reducing adverse events and preventing payment for useless drugs.
