Intertek provides cleaning validations for manufacturers and contract manufacturers of APIs, finished products, excipients and pharmaceutical packaging.
Sampling Techniques
Setting Acceptable Residue Limits (ARL)
ARL is critical in cleaning validations and should be logically determined
ARL must be practical, achievable and verifiable
Decomposition products should be checked
Initial criteria is visual check
10 ppm limit – USP limit test (assuming residues to be as harmful as heavy metals), useful for materials with no toxicology data available, not applicable for potent compounds
NMT 0.1% of therapeutic dose limit – minimum daily dose of current product carried over into maximum daily dose of subsequent product, identify worst case scenario
Analytical Methods
Develop and validate analytical methods for cleaning validations
Critical aspects are LOD, LOQ, precision, linearity, selectivity, recovery-spiking, consistency of recovery
Use validated methods for routine analysis of cleaning validation samples
Non-Specific Methods
API-Specific Methods
Develop and validate methods to specifically identify and quantitate APIs (including biopharmaceuticals) after cleaning procedure
If an active drug is highly toxic, a specific method is always recommended
