In this lecture, EKG is going to cover an introduction to pharmacology and introduce you to one of the fundamental concepts, which is pharmacodynamics. It's the study of how drugs produce their biological effects and how drugs will affect the different systems of the body. In other words, what does the drug do to the body?

We’re going to break down what a drug is, how drugs produce their effects on the body, and introduce you to the different types of drug targets. In later pharmacodynamics lectures, we’re going to expand on these topics.
