What does pharmacology study?

Pharmacology is the scientific study of drugs and how they interact with living organisms. This field encompasses the examination of drug properties, effects, mechanisms of action, therapeutic uses, and potential side effects. Understanding pharmacology is crucial in fields like medicine and public health because it helps professionals determine how drugs can be used effectively to treat illnesses, alleviate symptoms, and promote health.

While options discussing physical activity, herbal remedies, and psychological therapies may align with health and wellness, none focus specifically on the study of drugs as pharmacology does. The definition provided in the correct answer encompasses a broad spectrum of substances, including prescription medications, over-the-counter drugs, and recreational substances, allowing for an in-depth understanding of their biological impacts. Thus, the focus on drugs and their specific effects on living organisms is what clearly differentiates pharmacology from the other subjects listed.
