In accordance with the Rules and Procedures of the 2010–2015 Council of Experts, the Monographs—Small Molecules 4 Expert Committee has revised the Alprazolam Extended-Release Tablets monograph. The purpose for the revision is to add Dissolution Test 4 for a product approved by the FDA.

The Alprazolam Extended-Release Tablets Revision Bulletin supersedes the currently official Alprazolam Extended-Release Tablets monograph. The Revision Bulletin will be incorporated in the First Supplement to USP 37–NF 32.
