Pharmacogenomics in pain treatment
Drug Metabolism and Personalized Therapy
|September 24, 2016
Summary
Pharmacogenetics (PGx) offers personalized pain management by analyzing genetic variations that influence drug response and pain sensitivity. This review explores PGx evidence for optimizing chronic pain treatments and minimizing side effects.
Area of Science:
- Pharmacogenomics and Pain Medicine
- Clinical Pharmacology and Genetics
Background:
- Chronic pain is a prevalent clinical challenge with significant inter-individual variability in treatment response.
- Genetic factors, including single nucleotide polymorphisms (SNPs), influence drug pharmacodynamics and pharmacokinetics, affecting analgesic efficacy and toxicity.
- Limited robust evidence has hindered the clinical adoption of pharmacogenetics (PGx) for pain management.
Purpose of the Study:
- To review the evidence supporting the use of pharmacogenetics (PGx) for individualizing chronic pain therapy.
- To explore genetic factors influencing pain sensitivity and analgesic responses.
- To discuss the application of pharmacological concepts within PGx for pain medicine.
Main Methods:
- Review of existing scientific literature on pharmacogenetics in chronic pain.
- Analysis of genetic variability related to pain sensitivity and drug response.
- Examination of pharmacological principles applied to PGx in pain management.
Main Results:
- Genetic variations in genes affecting drug metabolism and targets contribute to variable responses to analgesics.
- Emerging evidence suggests PGx can guide treatment selection to improve efficacy and reduce adverse events in chronic pain.
- Novel therapeutic strategies, including epigenetics and gene therapy, are expanding future treatment possibilities.
Conclusions:
- Pharmacogenetics holds significant promise for tailoring pain management strategies to individual patients.
- Further research and robust clinical utility evidence are needed to fully integrate PGx into routine pain care.
- Understanding genetic influences is crucial for advancing personalized medicine in chronic pain treatment.

01:29Pharmacogenetics and Pharmacogenomics: Overview
117
Pharmacogenetics and pharmacogenomics examine how genetic factors influence an individual's response to drugs. While pharmacogenetics focuses on the impact of specific genetic variants on drug effects, pharmacogenomics takes a broader approach, studying how genetic variation across populations contributes to differences in drug responses. These fields aim to explain why individuals may experience varying levels of efficacy or adverse reactions to the same medication.Variability in drug...

Genetic variations significantly influence drug response through pharmacokinetics, receptor interactions, and biologic milieu modifications. Pharmacokinetic alterations impact drug metabolism and clearance, affecting efficacy and toxicity. Variants in drug-metabolizing enzymes, such as CYP2C9 and CYP2C19, alter drug activation and elimination. For example, CYP2C9 loss-of-function variants require lower warfarin doses to prevent excessive bleeding, while CYP2C19 variants reduce clopidogrel...

01:27Pharmacogenetics of Drug Metabolism: Overview
88
Genetic polymorphism in drug metabolism is crucial to the inter-individual variability observed in drug responses. Drug metabolism primarily involves the chemical modification of drugs and other xenobiotics to enhance their elimination by increasing their polarity. Two main classes of enzymes mediate this biotransformation process: Phase I enzymes, primarily cytochrome P450s, catalyze oxidation and reduction reactions, while other enzymes, such as esterases, mediate hydrolysis, and Phase II...

72
The human genome is over 99.9% identical between individuals, yet genetic differences exist at millions of bases. The human genome contains approximately 3 million variant positions per individual, many of which are heterozygous, contributing to genetic diversity and individual traits. Genetic variations include single-nucleotide polymorphisms (SNPs), insertions, deletions, and copy number variations (CNVs).SNPs, the most common variation, involve single-base changes in DNA. These can be...

2.7K
Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...
