Which term describes the field that investigates how medicines affect the human body?

• A. Pharmacology
• B. Pharmacognosy
• C. Pharmacologists
• D. Local OSHA Plans

Answer: (A)

The field that investigates how medicines affect the human body is pharmacology. It covers how drugs produce effects by interacting with receptors and other biological targets, as well as how the body processes drugs—absorption, distribution, metabolism, and excretion (pharmacokinetics)—and how the strength and timing of a drug’s effect relate to its dose (pharmacodynamics). It also includes studying therapeutic uses, side effects, and interactions with other medications. The other terms refer to different things: pharmacognosy is the study of medicines from natural sources, pharmacologists are the scientists who study pharmacology, and local OSHA plans are about workplace safety regulations.
