Unit 1343: Comprehensive Pharmacotherapy

1. Introduction to Pharmacotherapy

• Overview of pharmacotherapy and its significance in healthcare
• History of pharmacology
  • Early drug use and discovery
  • Milestones in drug development
• Drug development process
  • Preclinical research
  • Clinical trials (Phases I-IV)
  • Regulatory approval
• Role of pharmacotherapy in modern healthcare systems

2. Pharmacokinetics and Pharmacodynamics

2.1 Pharmacokinetics

• Absorption
  • Routes of administration
  • Factors affecting absorption
• Distribution
  • Protein binding
  • Volume of distribution
• Metabolism
  • Phase I and Phase II reactions
  • Role of liver enzymes (e.g., CYP450)
• Excretion
  • Renal and hepatic pathways
  • Half-life and clearance

2.2 Pharmacodynamics

• Drug-receptor interactions
  • Types of receptors
  • Agonists, antagonists, partial agonists
• Dose-response relationships
• Therapeutic index and drug potency
• Mechanisms of drug action

3. Drug Classes and Mechanisms of Action

• Overview of major drug classes
  • Antibiotics
  • Analgesics and anti-inflammatory drugs
  • Cardiovascular drugs
  • Central nervous system agents
  • Endocrine drugs
  • Chemotherapeutic agents
• Mechanisms of action for each class
• Representative drugs and clinical uses

4. Therapeutic Drug Monitoring (TDM)

• Purpose and importance of TDM
• Drugs commonly monitored (e.g., digoxin, lithium, aminoglycosides)
• Methods of measuring drug levels
• Interpretation of results
• Adjusting doses based on TDM

5. Adverse Drug Reactions (ADRs) and Drug Interactions

• Types of ADRs
  • Type A (dose-dependent)
  • Type B (idiosyncratic/allergic)
• Common adverse effects and toxicities
• Drug-drug interactions
  • Pharmacokinetic interactions
  • Pharmacodynamic interactions
• Prevention and management of ADRs and interactions
