The USP-NF is a combined publication of standards from which two sources?

• A. Pharmacopeia and National Formulary
• B. Pharmacology and National Formulary
• C. Pharmacopeia and National Formula
• D. Pharmacopoeia and Formulary

Answer: (A)

This question tests knowledge of what two sources provide the standards that make up the USP-NF. The USP-NF combines the standards from the United States Pharmacopeia and the National Formulary. The Pharmacopeia offers official monographs for drugs, dosage forms, and related substances, establishing their identity, potency, and quality. The National Formulary provides standards for pharmaceutical ingredients and for certain preparations used in compounding and manufacturing. Together, they form the official reference used to ensure medicines meet consistent quality and safety requirements in the United States. Other options mix up terms: pharmacology is a field of study, not a standards publication; “National Formula” isn’t the official name of the NF, and “Formulary” alone isn’t the precise pairing with the Pharmacopeia.
