Consequently, a thorough understanding of the basic concepts is essential before one can tackle the more involved and applied areas of pharmacokinetics. "Basic Pharmacokinetics" consists of two parts: textual printed materials and highly interactive computer-based presentations. Together, these provide a useful combination that makes it easy to grasp basic principles. The computer-based information is presented in a self-instructional format, which introduces concepts, utilizing highly interactive graphical presentations and simulations. It visualizes the interplay between the different pharmacokinetic parameters, observing how the change in one or more of these parameters impacts the drug concentration-time profile in the body. Uniquely and carefully designed, the learning modules in the CD closely support and complement the text, providing the learner with an opportunity to reinforce his or her understanding of the principles presented.
