What does accumulation refer to in pharmacology?

• A. Drug build up in the body
• B. Drug elimination
• C. Drug metabolism
• D. Drug excretion

Answer: (A)

Accumulation means the drug is building up in the body over time. This happens when doses are given faster than the body can eliminate them, or when something slows elimination—like kidney or liver problems. Each dose adds to the amount already present, so levels can rise until they reach a point where they may cause toxicity or stronger effects. So the description that fits best is drug buildup in the body. Elimination, metabolism, and excretion describe how the body removes drugs or changes them for removal, not the buildup process itself. Elimination is the overall removal, metabolism is the body’s chemical change to the drug, and excretion is the actual removal via urine or other routes.
