The term 'pharmacology' is MOST accurately defined as:

• B. The study of drug excretion from the human body
• C. The study of how medications affect the brain
• D. The study of drugs that are produced illegally

Answer: (A)

Pharmacology is the study of drugs and their actions on the body. This field covers how drugs are absorbed, distributed, metabolized, and excreted (pharmacokinetics) as well as how they produce effects by interacting with cellular targets such as receptors and enzymes (pharmacodynamics). It also includes how drugs are used therapeutically, appropriate dosages, potential side effects, and interactions with other medications or patient factors. While many drugs influence the brain, pharmacology is not limited to the nervous system; it spans all body systems. It’s not solely about excretion or about illegal drugs, but about the broad science of drugs and their effects on the organism.
