Content Outline
PreviewUnit 1643: Comprehensive Pharmacology
1. Introduction to Pharmacology
- Definition and scope of pharmacology
- Overview of drug therapy and its importance
2. Pharmacokinetics and Pharmacodynamics
2.1 Pharmacokinetics (PK)
- Absorption: routes, factors affecting absorption
- Distribution: blood flow, plasma protein binding, volume of distribution
- Metabolism: phase I and phase II reactions, liver enzymes (CYP450 system)
- Excretion: renal and non-renal routes
- PK parameters: half-life, clearance, bioavailability
2.2 Pharmacodynamics (PD)
- Drug-receptor interactions
- Dose-response relationships
- Therapeutic window and index
- Mechanisms of drug action
3. Drug Interactions
3.1 Pharmacokinetic Interactions
- Absorption interactions (e.g., chelation)
- Metabolic interactions (enzyme induction and inhibition)
- Excretion interactions
3.2 Pharmacodynamic Interactions
- Synergism, antagonism, and additive effects
- Examples of clinically significant drug interactions
4. Pharmacogenomics
- Definition and significance
- Genetic polymorphisms affecting drug metabolism (e.g., CYP2D6, CYP2C19)
- Impact on drug efficacy and toxicity
- Personalized medicine and tailored therapies
5. Drug Development and Approval Process
5.1 Stages of Drug Development
- Preclinical research
- Clinical trials (Phase I-IV)
5.2 Regulatory Approval
- Role of regulatory agencies (FDA, EMA, etc.)
- Submission and review of data
5.3 Post-Marketing Surveillance
- Pharmacovigilance
- Reporting adverse drug reactions
6. Drug Classes and Mechanisms of Action
- Overview of major pharmacological categories:
- Antibiotics
