Risk-Management Assessment of Visible-Residue Limits in Cleaning Validation
A risk-management assessment of visible-residue limits (VRL) in cleaning validation of pharmaceutical formulations was conducted for both pharmaceutical pilot plant and manufacturing facilities. The authors discuss how potential risks were identified, analyzed for probability, considered for seriousness, and controlled through avoidance or mitigation. These opportunities for VRL implementation then were identified for both pilot plant and manufacturing settings.
