The document discusses the development of cleaning methods in pharmaceutical education, emphasizing stages such as feasibility, development, and validation. It outlines various cleaning agents, sampling techniques, and parameters for cleaning validation levels, detailing acceptance limits and the analytical methods required for ensuring effectiveness. Additionally, it addresses the importance of selection and validation of cleaning processes to maintain product safety and compliance.

Cleaning method development
• Cleaning method development is a continuous progress in
parallel with evaluation of drug
Method development consist of three main stages:
Feasibility- determine if the method will work with your sample.
Development- where optimised method.
Validation- where optimised method is validated.

Tips for cleaning method
development
• Selection of cleaning process: manual verses automated.
• Cleaning data from the past as difficult to clean any product.
• Our strategy for the cleaning as a process.
• Worst case should be selected that is hard to clean.
• Determination of temperature of water and cleaning agent.
- volume of water to be used for cleaning.
- contact time of cleaning agent.

Continuation
• Selection of cleaning agent and its concentration that can clean
the residue.
• Recovery factor to determine analysis of product and detergent
residue
• A proper validated analytical method should be selected according
to nature of product and cleaning agent.
• sampling location should be selected considering hard to clean
place.

• The analytical method should be validated before cleaning
validation is performed.
• The method chosen should detect residues and contaminants
specific for the substance should be analyzed
• Validation of analytical method should include
• Precision
• Linearity
• Accuracy
• Limit of detection
• Limit of quantification
• Ruggedness
• Robustness

• Method selected should be specific and sensitive.
Specific and non specific methods
• Specific methods -Detects unique compounds in the presence of
potential contaminants Eg:HPLC
• Non specific method -detects any compounds that produce
response Eg:pH and conductivity
• Other methods
• Thin layer chromatography: determination of surfactants.
• atomic absorption spectroscopy: determination of inorganic
contaminants

• The acceptance limit established for contaminant level in the
sample should be practical, achievable and verifiable.
• NMT 10 ppm of any product will appear in another product.
• No quantity of residue should be visible on the equipment after
cleaning process are performed.
• For certain allergic ingredients the limit should be below limited of
detection.
