Abstract
Aim: A high throughput ultra-performance liquid chromatography (UPLC)-ultraviolet method for quantification of nintedanib in rat and human plasma was developed and optimized using chemometrical approach. Method: Design of experiment and multivariate statistical approach was used for definition of optimized method. Final separation was performed using protein precipitation method on ACQUITY HSS T3 C18 column in isocratic mode using potassium phosphate buffer (pH 7.5): acetonitrile. Results: Method was validated as per US-FDA guidelines linearly from 15-750ng/ml. All quality control samples showed <15% relative standard deviation for precision and 85-115% accuracy along with >98% extraction recovery. Conclusion: The developed method is easily applicable in determining pharmacokinetic parameters in preclinical subjects along with successful implementation for quantification in human plasma samples.
