Drug Reference Standards

The FDA's Orange Book (for small-molecule drugs) and Purple Book (for biologics) are the authoritative sources for Reference Listed Drugs in the United States. The U.S. Pharmacopeia (USP) catalog is the primary resource for Reference Standards. VuRoyal Pharmaceutical can help research organizations and clinical trial sponsors procure reference drugs listed in these official databases with full regulatory compliance.

Reference drugs, also called Reference Listed Drugs (RLDs), are FDA-approved drug products that generic drug applicants use as a basis for demonstrating bioequivalence. They are listed in the FDA Orange or Purple Book. Reference Standards are highly characterized substances used in analytical procedures to test the quality, purity, and potency of pharmaceutical products under USP guidelines.

Drug reference standards procurement in the U.S. is governed by U.S. Pharmacopeia (USP) guidelines, Title 21 of the Code of Federal Regulations (CFR), the Prescription Drug Marketing Act (PDMA), and the Drug Supply Chain Security Act (DSCSA). VuRoyal Pharmaceutical maintains full compliance with all these regulations as an FDA-registered, Massachusetts-approved pharmaceutical wholesaler.
