Study Notes
Precision Medicine
- Tailored healthcare based on an individual's unique genetic makeup.
- Analyzes genes and variations to identify potential treatments.
Population Screening vs. Pharmacogenetics
- Population screening: Targets individuals within specific populations for diseases with higher prevalence.
- Pharmacogenetics: Utilizes individual genetic information to determine optimal drug therapies.
Pharmacodynamics and Pharmacokinetics
- Pharmacokinetics: Analyzes the body's absorption, distribution, metabolism, and excretion of drugs and metabolites.
- Pharmacodynamics: Predicts an individual's response to specific medications.
ADME: Absorption, Distribution, Metabolism, and Excretion
- Absorption: Details how drugs enter the bloodstream.
- Distribution: Describes where the drug travels within the body.
- Metabolism: Explains the breakdown of drugs within the body.
- Excretion: How drugs are eliminated from the body.
Metabolism and the Liver
- The primary site for drug metabolism in the body. .
- Xenobiotics: Foreign compounds, including drugs, that require metabolism.
- Cytochrome P450: Enzyme family responsible for metabolizing xenobiotics in the liver.
Phase 1 and Phase 2 Metabolism
- Phase 1: Involves adding a hydroxyl group to the drug, increasing its water solubility.
- Phase 2: Further modifies the drug for easier excretion.
Cytochrome P450 Enzymes
- A family of enzymes encoded by over 56 genes.
- Each enzyme specializes in metabolizing different drugs.
- CYP3A4: The most significant enzyme, responsible for metabolizing a majority of drugs.
Precision Medicine
- Tailored healthcare based on individual's genotype.
- Analyzes genes and variations to predict optimal treatment.
Population Screening vs. Pharmacogenetics
- Population screening: tests individuals for diseases prevalent in specific populations.
- Pharmacogenetics: analyzes an individual's genes for personalized treatment.
Pharmacokinetics and Pharmacodynamics
- Pharmacokinetics: studies drug absorption, transport, metabolism, and excretion.
- Pharmacodynamics: predicts individual drug response based on body's characteristics.
ADME: Absorption, Distribution, Metabolism, and Excretion
- Absorption: how drugs enter the bloodstream.
- Distribution: where drugs travel within the body.
- Metabolism: breakdown of drugs within the body.
- Excretion: elimination of drugs and their byproducts.
Metabolism and the Liver
- Primary site of metabolism for most drugs.
- Xenobiotics: foreign compounds, including drugs, metabolized by the body.
- Cytochrome P450: enzyme family in the liver metabolizing xenobiotics.
Phase 1 and Phase 2 Metabolism
- Phase 1: adds hydroxyl groups to drugs, increasing water solubility.
- Phase 2: further modifies drugs for easier excretion.
Cytochrome P450 Enzymes
- Family of enzymes encoded by over 56 genes.
- Each enzyme metabolizes different drugs.
- CYP3A4: the most significant enzyme, metabolizing a large percentage of drugs.
