Study of the Effect of pH on the Cleaning of Fexofenadine in a Stainless-Steel Reactor by the Rinsing and Swabbing Method

The cleaning in the pharmaceutical industry is involved in each process of manufacture of drugs, it assure the quality of the final product. Cleaning is a key position in the fight against the risks of cross-contamination (chemical, microbiological and particulate) of drugs. The aim of this work is the study of the influence of pH on the cleaning of fexofenadine in a stainless steel reactor. Two cleaning methods were studied, the rinsing method and the swabbing method.
