FDA Publishes Guidance on Impurities in ANDAs

Full Text Here

This guidance provides recommendations on what chemistry, manufacturing, and controls (CMC) information sponsors should include regarding the reporting, identification, and qualification of impurities that are classified as degradation products in drug products when submitting:
• Original abbreviated new drug applications (ANDAs)
• ANDA supplements for changes that may affect the quantitative or qualitative degradation product profile
The guidance also provides recommendations for establishing acceptance criteria for degradation products (specifically, degradation products of the active ingredient or reaction products of the active ingredient with an excipient(s) and/or immediate container/closure system) in generic drug products. The guidance will replace an existing 1998 draft guidance of the same name.
FDA’s guidance documents, including this guidance, do not establish legally enforceable responsibilities. Instead, guidances describe the Agency’s current thinking on a topic and should be viewed only as recommendations, unless specific regulatory or statutory requirements are cited. The use of the word should in Agency guidances means that something is suggested or recommended, but not required.
