Utilisation de la spectroscopie de fluorescence pour la vérification du nettoyage d'un ingrédient pharmaceutique actif sur les surfaces des équipements de production
|Abstract:||Cleaning verification is used to assess the cleanliness of pharmaceutical process equipment. Cleanliness is established when the concentration of the residue of a pharmaceutical ingredient is lower than an acceptance limit. The method used to perform this verification consists of collecting a sample using a swab, and to analyze it using high performance liquid chromatography. The issue with this method is that it can take up to 2 days before the results are obtained, and before the equipment can be released for the production of another batch of drugs. Therefore, there is an opportunity to develop a new analytical method to quantify cleanliness in real-time without sampling (contactless). The new method investigated in this thesis uses fluorescence for direct quantification of ibuprofen residue. In this proof of concept, the impact of various parameters on the fluorescence signal was assessed. The best way to prepare the standards and how to analyze them with the instrument (the TraC) were determined. Following the verification of a first calibration curve using in situ data collection, the equipment was modified to allow the evaluation of equipment with an acceptance limit lower than the quantification limit of the TraC. The plant tests also revealed that the TraC always gives a higher concentration than the traditional method. An upgraded unit was calibrated, and the limit of quantification was lowered. It was established that the method is accurate (recovery is between 85 and 115%) and precise (relative standard deviation is lower than 5%), and that the excipients studied have no impact on the signal. Calibration curves were also built for aluminum, bronze, polyethylene and brass. Finally, the proof of concept for the use of the TraC for the cleaning verification of ibuprofen was demonstrated, and it is recommended to implement the method at a first plant.|
