Type of Posting: Revision Bulletin

Posting Date: 27–Mar–2015

Official Date: 01–Apr–2015

Expert Committee: Monographs—Small Molecules 4

Reason for Revision: Compliance

In accordance with the Rules and Procedures of the 2010-2015 Council of Experts, the Monographs- Small Molecules 4 Expert Committee has revised the Raloxifene Hydrochloride Tablets monograph. The purpose for the revision is to add Dissolution Test 2 for a drug product approved by the FDA.

The liquid chromatographic procedure used in Dissolution Test 2 is based on analyses performed with a Symmetry C18 brand of L1 column manufactured by Waters. The typical retention time for raloxifene is about 3 minutes.

In addition, an alternative sample preparation is included for Identification test A to exclude interference of excipients from a different formulation.

The Raloxifene Hydrochloride Tablets Revision Bulletin supersedes the currently official monograph. The Revision Bulletin will be incorporated in USP 39–NF 34.
