This course provides a foundational understanding of how chemical agents interact with the human body, covering the core principles of pharmacology—including drug mechanisms, pharmacokinetics, and therapeutic applications—alongside the essential concepts of toxicology, such as the effects, detection, and management of poisons and drug overdoses. Participants will learn to classify major drugs, predict their desired and adverse effects, and understand the fundamental principles of antidotes and treatment strategies for common toxic substances. This knowledge is critical for ensuring the safe and effective use of medications and for responding appropriately to potential toxicological emergencies in a clinical setting.
