Pharmacopoeia of the United States

The Pharmacopoeia of the United States (USP) is an official reference book that sets standards for the quality, strength, purity, and packaging of medicines and related substances in the U.S. Its purpose is to ensure that drugs are safe and effective for patients. The USP provides detailed descriptions and testing methods for thousands of pharmaceutical ingredients and products, guiding manufacturers and healthcare providers in maintaining consistent quality. By establishing these standards, the USP helps protect public health and supports the safe use of medicines across the country.
