Which field is primarily concerned with how drugs interact with living organisms, including their therapeutic uses?

• A. Recombinant DNA technology
• B. Pharmacology
• C. Alkaloids
• D. Active components

Answer: (B)

Understanding how drugs interact with living organisms and their therapeutic uses is pharmacology. This field covers what drugs do to the body and what the body does to drugs—pharmacodynamics and pharmacokinetics—including how a drug is absorbed, distributed, metabolized, and excreted, and how its effects relate to dose. It explains mechanisms of action, receptor targets, and how these interactions translate into indications, efficacy, safety, and potential adverse effects. Other options describe categories or tools rather than a discipline: recombinant DNA technology focuses on genetic engineering; alkaloids are a class of chemical compounds; active components is a vague term not describing a formal field.
