1. Introduction to Pharmacodynamics Pharmacodynamics (PD) is the branch of pharmacology that focuses on the effects of drugs on the body, including the mechanisms of action, the relationship between drug concentration and effect, and the factors influencing the drug’s response. In essence, pharmacodynamics seeks to answer the question: What does the drug do to the … Read more
