The science focusing on how medications affect bodily functions is known as?

• A. NF
• B. Parenteral medications
• C. Pharmacognosy
• D. Pharmacology

Answer: (D)

Understanding how medications affect bodily functions is pharmacology. It explores how drugs interact with the body's systems, including mechanisms of action and how the body processes drugs (pharmacokinetics) and how drugs produce effects at different doses (pharmacodynamics). This knowledge helps in prehospital care to choose the right drug, determine the correct dose, and anticipate responses or adverse effects. Other terms describe different ideas: pharmacognosy studies drugs from natural sources, and parenteral medications refer to a route of administration (like injections) rather than the science itself; NF isn’t a recognized term for this discipline. Therefore, the science focusing on how medications affect bodily functions is pharmacology.
