Definition of Pharmacodynamics
Pharmacodynamics is best defined as:
- Study drug sources
- Drug effects on body — Correct Answer
- Study drug dosages
- Body effects on drug
Correct Answer: What the drug does to the body
Pharmacodynamics is the study of the biochemical and physiological effects of drugs and their mechanism of action. It is the response of the organism to the action of a drug — in simple terms, 'what the drug does to the body'.
Contrast: Pharmacokinetics
Pharmacokinetics is the study of the actions of drugs in the body over a defined period of time — absorption, distribution, biotransformation and excretion — in simple terms, 'what the body does to the drug'.
Memory Aid
PharmacoDynamics = Drug acts on body. PharmacoKinetics = body Kills/processes drug.
