Which are considered Official Compendia?

• A. Official U.S. Pharmacopeia (USP) only
• B. Official Homeopathic Pharmacopoeia of the U.S. (HPUS) only
• C. Official National Formulary (NF) only
• D. Official USP, HPUS, and NF

Answer: (D)

Official compendia in the U.S. are the recognized references that set official standards for drugs, including their identity, strength, quality, and purity. The United States Pharmacopeia (USP) provides general drug standards; the National Formulary (NF) lists official drug substances and dosage forms; and the Homeopathic Pharmacopoeia of the United States (HPUS) provides official standards for homeopathic drugs. Today, USP and NF are published together as USP–NF, while HPUS remains the official compendium specifically for homeopathic medicines. Because each of these serves as an official standard reference used to ensure drug quality and regulatory compliance, the correct answer includes all three.
