Drug Biotransformation & Molecular Mechanisms of Toxicity
PHA 6425 Drug Biotransformation & Molecular Mechanisms of Toxicity


This course is 3 credits.


This course provides a strong conceptual foundation of enzymology and mechanisms of drug biotransformation pathways. As a foundation for learning, we will provide examples of drugs and other xenobiotics that exhibit toxicity related to biotransformation. Students are expected to use information presented in each module to develop and complete given assignments. Other activities will include online discussions of current news articles and scientific publications that relate to drug metabolism, toxicology and biochemistry.
