The purpose of this course is to explore the problems involved with administration of drugs; through analyzing and solving such problems, students will understand problem solving techniques using drug delivery system and build on knowledge to new technologies. Drugs to be dealt with in this course refer to small chemical drug, protein, gene and cells used in the treatment of diseases. For protein drugs, students will learn about drug delivery systems using chemically/physically combined technologies, manipulative technologies, formulation and device technologies. For polyssacharide drugs, students will learn about non-invasive delivery using chemical derivatives, and for genetic drugs, viral or non-viral vector systems. Furthermore, students will learn about cell delivery technology using the DNA manipulative cell technology, as well as protein delivery technology that is based on this technology. The course focuses on the understanding of the basic principles of the above and the analysis of recent technologies being researched in the field.
