Which term describes the study of the therapeutic use of medications and patient response?

• A. Pharmacotherapeutics
• B. Pharmacokinetics
• C. Pharmacodynamics
• D. Absorption

Answer: (A)

Pharmacotherapeutics focuses on how medications are used to treat illness and how patients respond. This field centers on selecting appropriate drugs, dosing regimens, routes of administration, and monitoring to optimize therapeutic benefit while minimizing adverse effects, taking into account patient-specific factors. Pharmacokinetics, by contrast, describes what the body does to a drug—absorption, distribution, metabolism, and excretion—while pharmacodynamics explains what the drug does to the body, including its mechanisms of action and effects. Absorption is a component of pharmacokinetics that concerns how a drug enters the bloodstream, not the broader study of therapeutic use and response.
