Method Development of Swab Sampling for Cleaning Validation of a Residual Active

ead more

A swab-sampling method was developed for cleaning validation of a residual active pharmaceutical ingredient in samples collected after cleaning the sampling suite. A summary of the strategies and results of the method development is presented. The developed extraction method produced an acceptable level of recovery and precision.Cross contamination with active ingredients is a real concern. The Code of Federal Regulations (CFR) states that “Equipment and utensils shall be cleaned, maintained, and sanitized at appropriate intervals to prevent malfunctions or contamination that would alter the safety, identity, strength, quality, or purity of the drug product beyond the official, or other established requirements” (1). Cleaning validation is required in the pharmaceutical field to avoid potential clinically significant synergistic interactions between pharmacologically active chemicals (2).
