Study Notes
Ethnopharmacology: Understanding Drug Response Based on Race/Ethnicity
- Ethnopharmacology is a multidisciplinary field researching indigenous drugs and their biological effects.
- It explores biologically active agents traditionally used, observed, or employed by humans.
- The field looks at how cultural beliefs and ethnicity affect responses to medication.
- This includes factors such as drug absorption, metabolism, distribution, and excretion.
- Pharmacogenetics, the study of genetic variations in responses to drugs, plays a significant role.
- Historically, drug trials have often been conducted on white men, with results generalized to all patients.
Race, Culture & Ethnicity
- Race is considered a group of people with a common lineage, and genetic variations distinguish populations.
- Ethnicity refers to shared cultural traditions, genetic heritage, and/or geographic origins.
- Culture encompasses beliefs, values, and customs passed down between generations.
Variability in Drug Response
- Patients in diverse ethnic groups experience different drug metabolisms.
- Pharmacodynamics (drug's action) and pharmacokinetics (drug's movement) both impact how a drug is processed in different groups.
- Genetic variations can influence enzyme function, leading to differing responses to medication.
- Diet and tobacco use can also change a person's gene expression, affecting drug effectiveness.
CYP 450 System
- Cytochrome P450 enzymes (CYP) are responsible for metabolizing many drugs.
- Many CYP subgroups exist, identified by letters and numbers (e.g., CYP2C9, CYP2D6).
- Genetic variations in CYP enzymes can significantly alter drug metabolism rates.
- These variations affect how quickly a person metabolizes a drug, influencing drug plasma levels.
Genetic Polymorphism
- Polymorphism describes different forms of a gene existing in individuals or populations.
- Drug-metabolizing enzymes have polymorphisms causing different responses and rates of metabolism within different racial groups.
- Some people are "ultrarapid metabolizers," quickly metabolizing drugs, while others are "poor metabolizers," slowly metabolizing them.
- Genetic deviations influence drug reactions.
Clinical Implications
- Careful monitoring of patients is crucial to avoid adverse effects and dosage adjustments.
- It is essential to understand and communicate with patients from various cultures properly.
- Cultural attitudes and racial biases can affect prescribing practices.
- Determining a patient's language preferences is important.
- Understanding the varied terms individuals use to describe illnesses is key.
- Pharmacogenomics plays an ever-increasing role in targeted drug therapies.
Drug Metabolism
- Drugs and other xenobiotics are transformed by the body into more hydrophilic metabolites for excretion.
- The primary site for this transformation is the liver and is a result of phase 1 (e.g., oxidation, reduction, or hydrolysis) and phase 2 (e.g., conjugation) reactions.
- CYP enzymes and transferases carry out these reactions.
- Differences in the function of drug metabolizing enzymes lead to varying drug metabolism in different populations.
Polymorphisms in Clinical Practice
- Genetic differences across populations affect enzyme performance.
- These differences show variable metabolism rates and drug reactions within racial groups.
- The examples of drugs like warfarin, ACE inhibitors, beta-blockers, and isoniazid highlight these variations.
Pharmacogenomics
- Pharmacogenomics is the study of how genes affect a person's response to medication.
- Drugs are tailored to patients' genetic makeup, leading to more effective and safer treatment.
- Genetic profiles aid in tailoring drug therapies to improve effectiveness and minimize adverse reactions.
