Study Notes
Drug Delivery Exam
- The exam is for the course "Drug Delivery" with course number 22235
- The exam is a written exam, held on 31st May 2021, and lasts for 2 hours
- All aids are allowed, and the exam consists of two questions, each worth 30 points
Question 1: Designing Liposome Formulations
- The question involves designing temperature-sensitive liposome formulations loaded with the chemotherapeutic doxorubicin
- The design choices must be explained, and the chemical structures provided should be used
- Three parts to the question:
- Part A: Design a liposomal bilayer for rapid drug release at physiological temperatures
- Part B: Design a liposomal bilayer for slow drug release at physiological temperatures
- Part C: Design a doxorubicin-loaded liposome that circulates for prolonged periods, is engulfed by cancer cells, and releases the drug upon heating to 44°C
Key Requirements for Design Choices
- Fundamental science underpinning the design choices
- Physicochemical properties of the system
- Biological interactions with the system in vivo
- Foreseeable challenges with the system
