USP Standards support every stage of drug development and manufacturing, saving time and resources which contribute to the acceleration of the development of quality medicines.

The use of USP Standards (Pharmacopeial Reference Standards and Pharmacopeial Documentary Standards Method) enables companies to operate with a high level of certainty and confidence, reducing the risk of incorrect results that could lead to unnecessary batch failures, product delays, and market withdrawals.
