The filling process of liquid suspensions is a difficult operation,mainly due to drug settling. Small variations during the process may lead to serious deviations in the API content uniformity of the finished product, particularly if the drug settles fast. Real-time non-invasive monitoring of liquid suspensions is a useful approach to ensure an acceptable API content in the finished product. The aim of this study was to develop a method based on non-invasive turbidity measurements for in-line determinations of betamethasone content uniformity during the filling process of injections. Owing to the constructive features of the developed system, the determinations were performed in a non-destructive and non-invasive way, thus allowing the analysis of the whole batch and minimizing the risk of contaminating the product. The results obtained by the method proposed in this study demonstrated that non-invasive turbidimetry is a powerful tool for continuous monitoring of the filling process of betamethasone injections, within the Quality by Design framework (FDA, 2009).
