Application of an innovative design space optimization strategy to thedevelopment of LC methods for the simultaneous screening of antibiotics to combat poor quality medicines
[en] The poor quality of medicines is a crucial problem of public health. Therefore, it is important to haveanalytical tools to attend decisions of the legal authorities while combating this offense. In this context,the main objective of this study was to develop generic methods able to trace, screen and determineseveral antibiotics and common associated molecules by mean of liquid chromatographic techniques.For that purpose, an innovative Design Space optimization strategy was applied, targeting 16 antibioticsand 3 beta-lactamase inhibitors. The robustness of the developed method allowed using its use in anenvironment where operational factors such as temperature are not easy to control and eased its trans-fer to Ultra High Performance Liquid Chromatography. To demonstrate its ability to quantify the targetedmolecules, the developed and transferred method was fully validated for two active ingredients com-monly used in association, sulbactam and ceftriaxone, using the accuracy profile as decision tool. Basedon this successful step, the method was then used for the quantitative determination of these two activeingredients in three pharmaceutical brands marketed in the Democratic Republic of Congo. Two out ofthe three pharmaceutical products did not comply with the specifications
