USP Excipients update – February 2024 

USP Novel excipient information hub  

In a recent USP survey, 77% of respondents stated their concerns and challenges in advancing drug formulation using novel excipients. USP created a novel excipient information hub in response to this survey, where you can tell USP your challenges with novel excipients. Your input will help USP prioritise focus areas and explore new platforms (e.g., technical guides, application notes, exchange community, etc.) to engage with you. Visit the Novel Excipients information hub.
