Objective: To develop and validate a novel, specific, precise and simple UV-spectrophotometric method for the estimation of lornoxicam present in microsponges.

Methods: UV-spectrophotometric determination was performed with Thermo Scientific Evolution 201 UV-Vis spectrophotometer using methanol as a medium. The spectrum of the standard solution was run from 200-400 nm range for the determination of absorption maximum (λ max). λ max of lornoxicam was found at 353 nm. The absorbance of standard solutions of 3, 6, 9, 12 and 15, µg/ml of drug solution was measured at an absorption maximum at 353 nm against the blank. Then a graph was plotted by taking concentration on X-axis and absorbance on Y-axis which gave a straight line. Validation parameters such as linearity and range, selectivity and specificity, LOD and LOQ, accuracy, precision and robustness were evaluated as per ICH guidelines.

Results: Linearity for the UV-spectrophotometric method was noted over a concentration range of 3.0-15.0 µg/ml with a correlation coefficient of 0.9995. The limit of detection (LOD) and limit of quantification (LOQ) for lornoxicam was found at 1.26 μg/ml and 3.82 μg/ml respectively. Accuracy was in between 99.21 and 99.60%. % RSD for repeatability, intraday precision and interday precision were found to be 0.473, in between 0.478 and 0.619 and in between 0.855 and 1.818 respectively. The proposed UV method is found to be robust.

Conclusion: The proposed UV-Visible spectrophotometric method was validated according to the ICH guidelines and results and statistical parameters demonstrated that the developed method is sensitive, precise, reliable and simple for the estimation of lornoxicam present in microsponges.
