Combination Therapies and Personalized Medicine02:50

Combination Therapies and Personalized Medicine

4.9K
Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

Pharmacogenomics: Identification of New Drug Targets

119
Advances in genomics have profoundly influenced drug discovery by increasing both the speed and accuracy of pharmaceutical development. Pharmacogenomics, which examines how genetic variation influences drug response, facilitates the identification of novel therapeutic targets and enables patient stratification for personalized treatment. These strategies contribute to improved drug efficacy, minimized adverse effects, and more efficient clinical trial design.Mapping genetic differences...

Pharmacogenetics and Pharmacogenomics: Overview

248
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...

Dosage Regimen: Individualization

388
Individualization in dosing regimens is the customization of medication doses for individual patients. Its necessity arises from the goal of maximizing therapeutic benefits while minimizing risks. This approach is pivotal because human responses to drugs can vary widely; what is effective for one person may be inadequate or excessive for another. Interpatient (intersubject) variability refers to differences in drug responses between individuals, while intrapatient (intrasubject) variability...

Pharmacogenetic Phenotypes: Alterations in Pharmacokinetics, Drug Targets and Biologic Milieu01:29

Pharmacogenetic Phenotypes: Alterations in Pharmacokinetics, Drug Targets and Biologic Milieu

157
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...

Area of Science:

  • Evolutionary biology
  • Genetics
  • Personalized medicine

Background:

  • Personalized medicine concepts draw from evolutionary biology's Modern Synthesis.
  • Early statistical investigators quantified heritability and linked it to Mendelian genetics.
  • Understanding disease genetics fueled the Human Genome Project and personalized medicine.

Purpose of the Study:

  • To link personalized medicine to historical statistical and genetic investigations.
  • To critically evaluate the current state of genotype-phenotype relationships and omic data utility.
  • To identify limitations and propose recommendations for personalized medicine advancement.

Main Methods:

  • Literature review and synthesis of historical and current research.
  • Discussion of key concepts: genotype-phenotype relationship, common-disease-common-variant hypothesis, and omic data.
  • Analysis of social and behavioral barriers.

Main Results:

  • Significant knowledge gaps and conceptual limitations exist in understanding genotype-phenotype relationships and omic data application.
  • The common-disease-common-variant hypothesis is debated.
  • Rare genetic variants show emerging therapeutic potential.
  • Social and behavioral factors impede personalized medicine adoption.

Conclusions:

  • Current personalized medicine approaches face substantial scientific and practical hurdles.
  • Recommendations are provided to address limitations in genotype-phenotype understanding and omic data integration.
