The objectives of this course are mainly to prepare students with a good understanding of a variety of different drug delivery systems and drug targeting. This includes controlling drug delivery such as immediate-release drug delivery systems, delay-release drug delivery systems, sustained-release drug delivery systems, and controlled release dosage forms. Site-directed drug targeting will also be another focus of the course which includes the concept of drug targeting with drug carriers to specific organs or tissues such as brain, liver, spleen, and tumors will be discussed. The concept of passive and active targeting will be given. The advantages and disadvantages of drug carrier systems for drug targeting will be explored. These carrier systems include; liposomes, nanoparticles, dendrimers, and polymer conjugates.
