The USP Drug Classification 2025 was published January 15, 2025. The USP Drug Classification (USP DC) is an independent drug classification system intended for use by any stakeholder interested in a classification of drugs for use in formulary development or review in non-acute or outpatient care settings. USP DC is not intended to replace the final review provided by the local pharmacy and therapeutics (P&T) committees.

The classification system can be used for formulary support including but not limited to:
•    Building and mapping formularies
•    Reviewing formulary adequacy for a minimum baseline of drugs
•    Identifying drugs in a particular pharmacologic grouping
•    Reviewing formularies and comparing formulary design and benefits

Please Note: For those interested in additional terminology mappings, USP offers a premium subscription product, the USP DC PLUS with mappings to NDC and RxNorm codes.
