After establishing three or more times that a process can be repeated reliably to remove residues down to acceptable levels, a program can be implemented to maintain the state of validation where only periodical retesting is required. Cleaning validation can be incorporated in part in to the PQ process. Cleaning validation is done when it’s impractical to verify cleaning on 100% of the production equipment used in high-volume manufacturing operations. The prime purpose of validating a cleaning process is to ensure compliance with federal and other standard regulations. The most desirable is the direct method of sampling the surface of the equipment, another method being the use of rinse sampling. Direct surface sampling It involves the determination of the type of sampling material used and its impact on the test data to check the interference of the sampling material with the test. Establishing Scientifically Justified Acceptance Criteria for Cleaning Validation of Finished Drug Products. Validations of equipment cleaning procedures are mainly used in pharmaceutical industries to prevent cross contamination and adulteration of drug products hence is critically important2. Manual cleaning CIP (Clean-in-place) COP (Clean-out-of-place) Semi automatic procedures Automatic procedures Time considerations Number of cleaning cycles Sampling Technique9-15 Generally there are two types of sampling that are accepted.

swab sample taken from SS coupon was evaluated at room .... Equipment cleaning validation in an API facility is extremely important as cross contamination in one of the pharmaceutical dosage forms, will multiply the problem. In addition to the obvious problems posed by subjecting consumers or patients to unintended contaminants, potential clinically significant synergistic interactions between pharmacologically active chemicals are a real concern. equipment parts, lubricants, chemical cleaning agents and pieces of cleaning tools such as brushes and rags. FDA expects firms to have written standard operating procedures (SOP) detailing the cleaning process used for various pieces of equipment. This is a fairly convenient method in many cases and requires control over the solvent used for rinsing, the contact time and the mixing involved.
