Which compendium provides official standards for drug quality in the United States?

• A. United States Pharmacopeia
• B. Drug standards
• C. Generic drugs
• D. Bioavailability

Answer: (A)

In the United States, official standards for drug quality are published by the United States Pharmacopeia, commonly together with the National Formulary as the USP–NF. This compendium defines specifications for drug substances and products—such as identity, strength, purity, packaging, labeling, and the testing methods used to verify quality. The FDA relies on these USP standards as the recognized benchmark for ensuring consistent, safe, and effective medications. The other options don’t serve as the official standards compendium: one is a vague term, another describes a category of drugs, and the last is a pharmacokinetic measure, not a standards source.
