An isocratic, reversed phase-liquid-chromatographic method was developed for the quantitative determination of Levofloxacin and Cefpodoxime proxetil in combined-dosage form. Alliance -Waters System with Agilant Zorbax Eclipse XBD-C8, (150mm×4.6; 5µm) column with mobile phase containing water with Ortho phosphoric acid: Methanol in the ratio of (80: 20, v/v) was used. The flow rate was 0.5 ml/min, column temperature was 40°C and effluents were monitored at 270 nm. The retention times of Levofloxacin and Cefpodoxime proxetil were 3.096min and 4.559min, respectively. The correlation co-efficient for Levofloxacin and Cefpodoxime proxetil was found to be 1.0 and 1.0, respectively. The proposed method was validated with respect to linearity, accuracy, precision, specificity, and robustness. Recovery of Levofloxacin and Cefpodoxime proxetil in formulations was found to be in the range of 97-103% and 97-103% respectively confirms the non-interferences of the excipients in the formulation. Due to its simplicity, rapidness and high precision. The method was successfully applied for the estimation of Levofloxacin and Cefpodoxime proxetil in combined dosage form.

A simple, accurate, precise high-performance liquid chromatographic (HPLC) method has been developed and validated for the simultaneous determination of abacavir sulphate (ABA) and lamivudine (LAM) in combined dosage form. Separation was performed on a C18 column [Agilent ODS UG 5 column, 250 mm x 4.5 mm], with methanol: water (50:50 V/V) isocratic elution using a flow rate of 1mL/min. Good sensitivity was observed with UV detection at 277 nm. After method development, the interference of other active compounds and excipients, repeatability and linearity, were investigated. Retention times of LAM and ABA were found to be 3.3 and 6.3 min, respectively. The method was validated over the range from 2.5-12.5 μg/mL for LAM and 5-25 μg/mL for ABA with correlation coefficients of 0.9997 and 0.9996, respectively. This method was shown to be accurate, robust, selective, linear, and repeatable and can be successfully employed in routine quality control for the simultaneous analysis of ABA and LAM in tablets.

A simple, accurate and precise RP-HPLC method was developed for the simultaneous estimation of the linagliptin and empagliflozin in tablet dosage form. Chromatogram was run through Kromasil 250 x 4.6 mM, 5mM column, mobile phase containing 0.1% o-phosphoric acid buffer and acetonitrile in the ratio of 60:40%v/v was pumped through column at a flow rate of 1 mL/min. The optimized wavelength was 230 nm. Retention times of linagliptin and empagliflozin were found to be 2.759 min and 2.139 min. %RSD of the Linagliptin and Empagliflozin were found to be 0.5 and 0.6 respectively. Percentage assay was obtained as 99.91% and 100.15% for linagliptin and empagliflozin, respectively. LOD, LOQ values obtained for linagliptin and empagliflozin were 0.23 μg/ml and 0.44 μg/mL and 0.70 μg/mL and 1.34 μg/mL, respectively. Thus, the current study showed that the developed RP-HPLC method is sensitive and selective for the estimation of linagliptin and empagliflozin in combined dosage form.
