Introductory Pharmacology: Principles of Drug Action and Therapeutics

Understanding how medications interact with the human body is fundamental to modern medicine and healthcare. This course provides a clear, step-by-step introduction to the core principles of pharmacology without requiring a complex medical background. You will gain a solid grasp of how drugs are administered, absorbed, distributed, metabolized, and eliminated, as well as how they target specific biological pathways to treat diseases. What you'll learn: - Understand foundational pharmacology terminology, including pharmacokinetics and pharmacodynamics. - Analyze how different drug classes target specific physiological systems to treat and prevent diseases. - Explore modern therapeutic approaches, including biologics, targeted therapies, and personalized medicine basics. - Identify the mechanisms of drug absorption, distribution, metabolism, and excretion (ADME). - Evaluate drug safety, dosing principles, potential side effects, and drug-drug interactions. The course begins with essential definitions and foundational concepts before moving into specific drug classes, therapeutic applications, and modern pharmaceutical innovations. You will progress through structured text-based explanations and practical scenario-based review questions. Designed for beginners, pre-health students, and curious learners seeking a foundational understanding of pharmacology, with no prior medical prerequisites required.
