Which of the following refers to the study of drugs' effects on the body?

The study of drugs’ effects on the body is referred to as pharmacology. This field encompasses the understanding of how drugs interact with biological systems, detailing their mechanisms of action, therapeutic uses, potential side effects, and the overall impact on bodily functions. It allows healthcare professionals to make informed decisions about medication management, considering both efficacy and safety.

While therapeutics focuses specifically on the application of drugs for treating diseases and symptoms, and pharmaceutics deals with the formulation and delivery of medications, pharmacology provides a broader framework that includes both theoretical and practical aspects of drug interactions with the body. Immunology, on the other hand, is concerned with the immune system and does not primarily deal with drug effects. Thus, pharmacology stands out as the most encompassing field related to understanding drugs and their effects on biological systems.
