What is the Origin of Pharmacogenomic Guided Dosing?

This term is a core concept within pharmacogenomics, the scientific study of how genes affect a person's response to drugs and other compounds. 'Guided Dosing' refers to the practical application of this genetic insight to determine the appropriate and safe therapeutic quantity for an individual patient.

What is the Mechanism of Pharmacogenomic Guided Dosing?

Genetic testing identifies polymorphisms in genes like the Cytochrome P450 (CYP) family, which are responsible for metabolizing the vast majority of pharmaceutical agents and many steroid hormones. A patient identified as an ultrarapid metabolizer for a specific enzyme may require a higher dose to achieve a therapeutic level, whereas a poor metabolizer requires a much lower dose to prevent drug accumulation and toxicity, ensuring personalized treatment fidelity.

Pharmacogenomic Guided Dosing

Meaning

Pharmacogenomic Guided Dosing is the clinical practice of adjusting the dose or selection of a medication, hormone, or therapeutic agent based on an individual’s specific genetic makeup, particularly variations in their drug-metabolizing enzyme genes. This process leverages genomic data to predict how quickly or slowly a patient will process a compound, ensuring that the concentration at the target tissue is maintained within the optimal therapeutic window. This practice maximizes treatment efficacy while concurrently minimizing the risk of systemic toxicity or adverse side effects.
