Although the goal of prescribing medications is to achieve the intended therapeutic effect, patients frequently react differently to the same medication. Even at standard dosages, some people may have noticeable side effects from a medication, while others may tolerate it well.
This variation could be caused by several factors. The way a drug is absorbed, distributed, metabolised, and excreted from the body can be affected by variations in genetics, metabolism, age, body weight, and pre-existing medical conditions. For example, differences in the liver enzymes involved in drug metabolism can affect how quickly or slowly a medication is processed, resulting in varying patient responses. Pharmacogenomics, which investigates how genetic variations impact drug response, is the field that studies this idea.
Furthermore, adherence to recommended dosage, lifestyle choices, and drug interactions can all have an impact on whether a patient has negative side effects.
Comprehending these distinctions demonstrates the growing significance of personalised medicine in contemporary healthcare.
Do you think genetic testing and personalised medicine will become a routine part of prescribing medications in the future?
While major attention is given to drug-drug interaction, I have to mention here that drug-food interaction, can also show drug side effect. Most widely known is the interaction between grapefruit and statins (e.g., atorvastatin). Great overview, particularly about pharmacogenomics.
Very informative. Generalizing genetic testing for all drugs may not be practical idea. Particular drugs whose effectiveness and dosage is linked with specific genes can be categorized for mandatory gene testing prior to prescription.
informative, not everyone responds to a drug the same way, because of interindividuality variability, some patients do experience drug side effects while others not, that may be due the several factors- lifestyle factors, genetic variations.
integrating genetic testing into routine prescribing could significantly enhance drug safety and reduce ADRs. genetic testing is already used before prescribing certain drugs, especially in psychiatry, cancer. but that challenges may include - cost, awareness and training, accessibility and time.
Yes, this is the reason why Pharmacogenomics is gaining attention.May be in future genetic testing will become the part of our routine which may help in improving efficacy, reduce trial and error and ensure patient safety.
