Cleaning Verification

Cleaning Verification

Cleaning verification represents the procedure of verifying whether the manufacturing equipment is maintained as clean and uncontaminated to ensure the pharmaceutical products are produced without risk of residual unwanted substances. Those potential contaminants mainly include residues of the active pharmaceutical ingredients, degradation of certain compounds and even the detergents or solvents generated during the cleaning process. In this case, cleaning verification is an effective tool that can ensure that the process and processing equipment are suitable for manufacturing, prevent drug contamination and improve drug quality.
