BRIEFING
Crospovidone. This proposal is based on the version of the monograph official as of May 1, 2020. On the basis of comments received, it is proposed to update Identification D to remove "of the dried substance" from the sample preparation and to add "on the dried basis" to the calculation and Acceptance criteria.
Additionally, minor editorial changes have been made to update the monograph to current USP style.
