Accumulation means which of the following in pharmacology?

• A. Drug build up in the body
• B. Improved tolerance
• C. Faster metabolism
• D. Immediate cure

Answer: (A)

Accumulation means the drug is building up in the body because the amount taken with each dose isn’t fully cleared before the next dose is given. This happens when dosing happens at intervals that are short relative to the drug’s half-life, so each dose adds to the amount still present from earlier doses. Over time, the concentration climbs until it reaches a steady level after several half-lives. This concept matters for safety and effectiveness because higher levels can increase both desired effects and the risk of side effects or toxicity, guiding how long to wait between doses or whether to adjust the dose. The correct idea is the one that describes the drug as accumulating or building up in the body. The other options describe different concepts: tolerance is about a change in the body’s response to a drug, faster metabolism means quicker clearance (less accumulation), and an immediate cure has nothing to do with how drug levels rise in the body.
