The Interactive Clinical Pharmacology (ICP) site was designed to increase understanding of important and difficult concepts and principles in Clinical Pharmacology. It is not intended to be comprehensive for all aspects of Clinical Pharmacology teaching. It has been developed using Macromedia Flash to enable user interaction. The site is for any student or practitioner requiring Clinical Pharmacology knowledge, e.g. undergraduate and post-graduate students in medicine, pharmacy and pharmacology. A basic understanding of physiology and pharmacology is assumed.
