Fundamentals of Pharmacology: Drug Action, ADME, and Therapeutics

Understanding how drugs work is essential for anyone entering healthcare or life sciences. This course provides a clear, foundational explanation of the processes governing drug action and fate in the body. By the end of this course, you will possess a robust vocabulary and conceptual framework for analyzing drug effects, interactions, and therapeutic uses, setting the stage for advanced study in clinical science. What you'll learn: * Learn the fundamental principles of pharmacodynamics, including receptor theory and dose-response relationships. * Understand the four stages of pharmacokinetics: Absorption, Distribution, Metabolism, and Excretion (ADME). * Analyze how physiological factors, including age and disease state, influence drug efficacy and safety. * Master the concepts of therapeutic index, drug tolerance, drug dependence, and common adverse effects. * Identify basic principles of pharmacogenomics and how genetic variations influence individual drug responses. * Apply foundational knowledge to classify major drug classes based on their mechanism of action. We begin by establishing core terminology and defining key processes, moving systematically through pharmacokinetics before detailing the molecular mechanisms of pharmacodynamics. The course emphasizes clear written explanations and practical, real-world examples. This course is designed for absolute beginners, including pre-med students, nurses, biology majors, and anyone starting a career in the pharmaceutical or health sciences. No prior knowledge of pharmacology is required. Start building your essential foundation in drug science today.
