In silico modified UV spectrophotometric approaches to resolve overlapped spectra for quality control of rosuvastatin and teneligliptin formulation
Abstract
A binary blend of rosuvastatin (ROS) and teneligliptin (TEN) used for the management of cardiovascular complications require a simple, analytical process for the quality assurance of this formulation. UV absorption spectra of ROS and TEN showed overlapping spectra. Hence, the overlapped spectra of ROS and TEN were separated by ratio difference, ratio first derivative; constant extraction coupled with exponentiation with division spectrum, and induced dual-wavelength methods. The proposed methods were authenticated by following the international council for harmonization criteria. A good linear relationship was demonstrated by all four methods, in 2–15 and 2–30 µg/mL for ROS and TEN, respectively. The high percentage retrieval of 98.96–100.22 and 98.72–99.73% for ROS and TEN, respectively, with small relative error, assured the correctness of the techniques. The validated techniques were employed for concurrent evaluation of ROS and TEN from binary formulation and laboratory-prepared mixture. The standard addition process verified the reliability of the projected procedures. The developed methods showed same accuracy and precision when compared to the HPLC methods along with safer solvent. Finally, the environmental sustainability of the presented UV spectroscopic procedures was found to be better than the reported HPLC method. Hence, eco-friendly, simple, and accurate mathematically processed UV spectroscopic procedures can be employed for simultaneous quantification of ROS and TEN for routine quality control study.
