Assignment Questions
1. Pharmacokinetics Describe the four major processes of pharmacokinetics (ADME) and explain their significance in drug therapy.
2. Transport Across Plasma Membranes Explain how substances move across plasma membranes, including passive diffusion, facilitated diffusion, active transport, and endocytosis/exocytosis.
3. Drug Absorption Discuss key factors affecting drug absorption, including solubility, pH, route of administration, gastrointestinal motility, and patient-specific factors.
4. Plasma Proteins and Distribution Explain how plasma proteins influence drug distribution and describe the significance of drug-protein binding.
5. Physiological Barriers Explain the importance of the bloodbrain barrier, bloodplacenta barrier, and bloodtestes barrier in drug therapy.
6. Drug Metabolism Describe Phase I and Phase II metabolic reactions and explain their role in drug inactivation or activation.
7. First-Pass Effect Explain the first-pass effect and discuss its implications for oral medications.
8. Age and Metabolic Enzymes Compare drug metabolism in pediatric and geriatric populations and explain the clinical implications.
9. Intermediate Metabolites Explain how intermediate metabolites may produce stronger or toxic responses.
10. Drug Elimination Describe renal, hepatic, and alternative routes of drug elimination.
11. Enterohepatic Recirculation Explain how enterohepatic recirculation affects drug duration and dosing.
12. Half-Life and Duration of Action Explain the relationship between rate of elimination, plasma half-life (t½), and drug action duration.
13. Drug Concentrations Define minimum effective concentration (MEC), minimum toxic concentration (MTC), and therapeutic range.
14. Dosing Strategies Differentiate between loading doses and maintenance doses and provide clinical examples.
