Rivaroxaban, an anti-clotting medication, acts at a crucial point in the blood-clotting process and stops the formation of blood clots. In this study, RP-HPLC method was developed for the determination of rivaroxaban in tablets (Xarelto® (10 mg)). Phenomenex Luna 5 µm C18 100 Å LC Column (250 x 4.6 mm) was used at 40 ºC. Isocratic elution was performed with ACN:Water (55:45 v/v) mixture. The flow rate was 1.2 mL min-1 and UV detection was at 249 nm. Internal standard (Caffeine) and rivaroxaban were eluted within 2.21 and 3.37 minutes, respectively. The developed method was validated according to the ICH guidelines and found to be linear within the range 0.005 - 40.0 µg mL-1. The method was accurate, precise, robust and rapid. Thus, it was applied successfully for the quality control assay of rivaroxaban in tablet dosage form.

An RP-HPLC method was developed for the quantification of related impurities of lurasidone and its formulation. The chromatographic separation employs gradient elution using an Inertsil ODS C18 (150x4.6) mm, 5μm columns. Mobile phase consisting of solvent A-buffer (pH 3.0): methanol (90:10 %v/v) and solvent B-acetonitrile: water (80:20 % v/v) delivered at a flow rate of 1.0 mL/min. The analytes were detected and quantified at 210 nm using PDA. The method was validated as per ICH guidelines, demonstrating to be a simple, precise, selective, linear and accurate within the corresponding range of impurities of lurasidone. Linearity was observed in the concentration range of 2-6 µg/mL. The RT for Lurasidone was about 18.5 min and three known impurities at RRT about 0.15, 0.21 and 0.36. The specificity of the method was investigated under different stress conditions including hydrolytic, oxidative, photolytic and thermal as recommended by ICH guidelines. Relevant degradation was found to take place under oxidative conditions. Degradation impurities did not interfere with the RT of drug. The peak purity obtained with the aid of PDA detection and satisfactory resolution between related impurities established the specificity of the determination. All these results provide the stability indicating capability of the method.
