Purchase USP–NF

The USP–NF is a combination of two compendia, the United States Pharmacopeia (USP) and the National Formulary (NF). It contains standards for medicines, dosage forms, drug substances, excipients, biologics, compounded preparations, medical devices, dietary supplements, and other therapeutics. The current version of USP–NF standards deemed official by USP are enforceable by the U.S. Food and Drug Administration for medicines manufactured and marketed in the United States. The current version, USP–NF 2021, Issue 1, will become official on May 1, 2021

An ISO certified Spanish translation (certified to ISO 17100:2015) of USP–NF compendial content is available as the Spanish USP–NF Online.
