A Novel UV Spectrophotometric Approach Using Absorbance Correction for Concurrent Quantification of Meloxicam and Rizatriptan Benzoate
Abstract: A novel and highly accurate and cost-effective method for determining the concentrations of the two medications in solution by means of their UV absorbances correction was developed and validated based on the distinctively different UV properties of Meloxicam and Rizatriptan Benzoate. Although the spectra of absorbance for each of the two compounds overlapped, the developed method overcame the overlap (interference) by making use of a unique way to quantify each compound without the need for either separation or isolation. Validation of the proposed method, as per the ICH guidelines (linearity, limit of detection, limit of quantification, precision and accuracy) has successfully been accomplished with the use of methanol as the solvent for all of the studies performed. The calibration graphs for both Meloxicam (2-12 ?g/ml) and Rizatriptan Benzoate (2-12 ?g/ml) show significant linear regressions with all coefficients of determination greater than 0.9900. The recovery rates of 98-102% for both compounds correspond to the accurate quantification of both compounds. Precision studies indicated an %RSD value of <2% for intra-day and inter-day precision which further supports the precision and accuracy of the developed method. The method can be recommended as a viable alternative to chromatographic techniques and can be used for routine Quality Control analysis for both mixed preparations and product formulations.
