In a notice from 20 December 2011 the United States Pharmacopeia (USP) has notified that Chlorpheniramine Maleate Extended-Release Tablets RS will be withdrawn as of 1 February 2012.
These tablets had been used for testing the Performance Verification Suitability according to the General Chapter <711> for Apparatus 3.
This withdrawal is due to the fact that no suitable replacement candidate has been found to date.
USP remains convinced that a Performance Verification Test is a critical element in the qualification of dissolution apparatuses.
During the ECA Conference "Dissolution Testing - Development - Quality Control - and in vivo Relevance" taking place from 17-19 October 2012 in Berlin, the newest USP requirements concerning the qualification of apparatuses will be presented and compared to the FDA requirements on mechanical qualification.
