Created by : 
Duke University Medical Center, The North Carolina School of Science and Mathematics

In this interactive module, the distribution of drugs throughout the bloodstream and their accumulation in a specific target (i.e., hair) is used to teach students about the chemical properties of drugs, the properties of biological membranes, conversion of drugs to metabolites by enzymes in the liver, and more. This is one of six modules from the Pharmacology Education Partnership that helps high school students learn biology and chemistry concepts through the study of drugs.
