This paperback book provides an introduction to Cleaning Verification and Validation for pharmaceutical and biological equipment and facilities. It provides a practical framework for the design and execution of cleaning validation. Cleaning Validation is a regulatory requirement as per GMP. There are many organisations and bodies which provide guidance of implementing a Cleaning Program such as PIC/s ICH, PDA reports, EU GMP V4 to name a few. The key elements to achieving a successful cleaning validation include (1) understanding the sources of residues (soils, excipients, actives, microbes etc) (2) developing a cleaning procedure (3) developing a test method (4) validating the cleaning procedure in respect of the products and equipment to be used in manufacturing.Summary of title indexIntroduction,What is Cleaning, Why Clean,Verification and Validation Definitions, Regulatory Requirements FDA, EU GMP.
