Validation of blend uniformity is one of the critical steps in process validation for solids. Whereas in Europe there is no regulatory requirement with regards to the validation of blend uniformity, this is different in the USA. The 21 Code of Federal Regulation (CFR) 211.110 requires pharmaceutical manufacturers to demonstrate the adequacy of their mixing operations on a routine basis. Due to issues with sampling of powder blends, this topic is under discussion since the early 90s. Based on a PQRI recommendation, FDA published in 2003 the Draft Guidance “Powder Blends and Finished Dosage Units - Stratified In-Process Dosage Unit Sampling and Assessment“. This document described stratified sampling as method for the validation of the blend uniformity and proposed a sampling plan for final product testing. Although the guidance was never finalized, it represented the state of the art regarding blend uniformity testing until 2013 when it was withdrawn by FDA. Apart from sample size requirements the acceptance criteria for uniformity of dosage units no longer represented the agency’s „current thinking“.
What is today state of the art regarding the validation of blend uniformity? The webinar will provide an answer to this question.
The webinar targets employees who are involved in the validation of solids and want to know what is state oft he art regarding the validation of blend uniformity, e.g. head of production, head of validation, members from Quality Assurance departments.
