Cleaning validation

Rinse sampling

Total organic carbon

Correlation

Cleaning validation is one of recommendation from Pharmaceutical Inspection Co-operation Scheme(PIC/S)to avoid contamination of pharmaceutical products.The objective of cleaning validation is to confrm reliability of cleaning procedure for removal of contaminants associated with previous products,residues of cleaning agents and potential microbial contaminants[1].Japanese Encephalitis vaccine is a new product that is prequalifed by World Health Organization (WHO)and manufactured at GPO-MBP.Magnetic bar is dedicated for this product and used in stainless steel vessel, which is used for blending and flling processes of the fnal bulk product.

To validate the cleaning procedure for the magnetic bar,rinse sampling was applied.Total organic carbon(TOC)was used todetect product residue in rinsing solution.Correlation between TOC and diluted vaccine(vaccine and water for injection(WFI) ratio=9:1(v/v))can be expressed with a linear equation; y=40.589×–0.322.Coeffcient of determination(r2)is 0.9993. Recovery of the sampling technique is 92.7±9.45%.Acceptance criteria for the product residue was defned based on no more than 0.1%of the normal therapeutic dose of the product that will appear in the maximum daily dose of the product. Maximum residue of the previous product should not more than 3.7 μl/ml of rinsing solution.TOC values of rinsing solution from cleaning validation of magnetic bar were less than those of the positive control,and conformed to the acceptance criteria.In conclusion,cleaning procedure according to standard operating procedure of GPO-MBP is validated.
