Pharmacodynamics: What the drug does to the body, the biochemical and physiological effects of drugs on the body.This includes the drug’s mechanism of action, receptor binding, drug efficacy, drug potency, and toxicity.

Potency. amount of a drug that is needed to produce a given effect. e.g, EC50 is the concentration or dose of drug that causes 50% of maximum effect. determined by affinity of drug for receptor and number of receptors available. Potency is an expression of the activity of a drug in terms of the concentration or amount of the drug required to produce a defined effect, whereas clinical efficacy judges the therapeutic effectiveness of the drug in humans. Definition of Efficacy vs Potency. Efficacy is the ability of a drug after binding with receptors to initiate change which leads to certain effects.
