Comprehensive development and validation of a high-performance RP-HPLC method for the quantitative analysis of levocetirizine

The abstract discusses the reverse-phase high-performance liquid chromatography (RP-HPLC) method for the determination of Levocetirizine hydrochloride (HCl) in a tablet formulation and its validation. This effectiveness in treating allergic rhinitis and chronic idiopathic urticaria, Levocetirizine HCl, for its strong affinity to H1 receptors, entails accurate methods for identification and isolation. The RP-HPLC method was fine-tuned with a retention time of 3.87, a resolution of 1.34, and a plate count of 7125 to give sharp peaks and promising chromatographic separations. Validation was done in accordance with ICH guidelines using relevant methods like specificity, linearity (high correlation coefficient of 0.99997 across a concentration range of 2.0–30.0 μg/mL), accuracy (recovery), precision (repeatability and intermediate precision), limits of detection (LOD), and limits of quantification (LOQ). Among other data calculations from analyzing really circulating tablets, which confirmed the reliability of the methodology, the percent of the inactive substance in tablets in the test was close to what was expected. High rigidity and consistency are the factors that place the methodology in empirical QA labs for pharmaceutical quality control, even though the application of the method may differ from product to product. The technique naturally requires adherence to the standards, and this is its merit for the formulation of pharmaceutical formulations. Over and above, the RP-HPLC method is a selective, accurate, and reliable way of testing Levocetirizine HCl strength. This is a basic need for the product to be really potent and safe for the human body.
