Pharmacokinetics and Pharmacodynamics of Chemotherapy
Start with the big picture
The lesson connects drug handling in the body with treatment response. It introduces transporters such as P-glycoprotein, differences in distribution and clearance, and the limits drugs may face in reaching sanctuary sites. It also explains core response principles, including the log-kill hypothesis, cell-cycle specificity, and how tumor growth fraction relates to sensitivity. Treatment design is considered through combination therapy, dose intensity, schedule dependence, and the balance between antitumor effect and dose-limiting toxicity. The topic further introduces carboplatin dosing by AUC and pharmacodynamic endpoints, while placing resistance and therapeutic drug monitoring within the broader framework of chemotherapy optimization.
What you'll learn
- Describe how drug transporters can reduce intracellular chemotherapy exposure and contribute to resistance.
- Distinguish key influences on distribution, metabolism, elimination, and drug penetration.
- Explain the log-kill hypothesis and the difference between cell-cycle-specific and nonspecific agents.
- Relate tumor growth fraction, combination therapy, and treatment scheduling to response.
- Identify how dose-limiting toxicity and AUC-based carboplatin dosing inform treatment design.
