What does "USP" stand for in the context of pharmacy?

"USP" stands for United States Pharmacopeia, which is an important organization in the field of pharmacy. The USP is responsible for establishing and maintaining quality standards for medicines, food ingredients, and dietary supplements. These standards ensure that the products are safe, effective, and of the necessary quality for public health. The USP publishes the official compendium of standards that include monographs, which provide detailed information about the identity, quality, and strength of various substances used in medicine. This is critical for pharmacy practice, as it helps pharmacists and manufacturers ensure they are providing high-quality products to patients. The other options do not accurately represent the primary role and purpose of the USP in the pharmacy context.
