Screenshot 2024 03 21 172145 Pharmacodynamics: Introduction, Concepts and applications

Pharmacodynamics is the branch of pharmacology concerned with the biochemical and physiological effects of drugs on the body and their mechanisms of action. It explores how drugs interact with their molecular targets, leading to physiological responses, and how these responses vary across different individuals and conditions. Understanding pharmacodynamics is crucial for optimizing drug therapy, predicting … Read more
