Residual Solvents by HT3 Headspace in Reference to USP 467
Residual solvents in pharmaceuticals are defined as volatile organic chemicals that are used or produced in the manufacture of drug substances, excipients or in the preparation of drug products. Because residual solvents do not provide therapeutic benefits, they should be removed, to the extent possible. Drug products should contain no higher levels of residual solvents than can be supported by safety data. Looking forward to the implementation of a revised USP 467 method, Teledyne Tekmar evaluated the new protocol, therefore this application will comply with the procedure and criteria changes set forth in the USP30 NF25, Second Supplement (effective December 1, 2007) and the interim revision announcement.
