Final answer:
Pharmacogenomics can assist patients on Warfarin by determining the appropriate dosage based on genetic variants and identifying those who may not respond well to the drug.
Step-by-step explanation:
Pharmacogenomics, a field that combines pharmacology and genomics, can be used to assist patients who are prescribed Warfarin (Coumadin). It involves studying how an individual's genes affect their response to a particular drug.
Through pharmacogenomics, genetic tests can be conducted to identify variants in genes that are involved in the metabolism of Warfarin. By knowing these genetic variants, healthcare professionals can determine the appropriate dosage of Warfarin for each patient, minimizing the risk of overdose.
Additionally, pharmacogenomics can help identify individuals who may not respond well to Warfarin or who are at a higher risk of adverse reactions. This information can guide healthcare providers to explore alternative medications or treatment options for these patients.
