Liquid Chromatographic

A simple, selective and rapid reversed phase High Performance Liquid Chromatographic (RP-HPLC) method has been developed and validated for the simultaneous analysis Gatifloxacin and flurbiprofen sodium in eye drops. The separation was carried out using a mobile phase consisting ACN: Buffer (pH 3.5) in the ratio of 55:45 v/v. The column used was Phenomenex luna ODS C18 (250mm X 4.6 mm i.d., 5 μm particle size) with flow rate of 1 ml / min using UV detection at 268 nm. The described method was linear over a concentration range of 2-12 μg/ml for both of Gatifloxacin and flurbiprofen sodium. The retention times of Gatifloxacin and flurbiprofen sodium were found to be 3.710 min. and 6.797 min respectively. Method was validated statistically and recovery studies were carried out. The proposed method has been applied successfully to the analysis of cited drugs either in pure form or in pharmaceutical formulations with good accuracy and precision. The method here in described can be employed for quality control and routine analysis of drugs in pharmaceutical formulations.

Development And Validation

A new simple, accurate ,precise and reproducible RP-HPLC method has been developed for simultaneous estimation of metformin and pioglitazone in bulk drug form using proper HPLC system. The mobile phase consists of phosphate buffer and acetonitrile in the ratio of 35:65 at pH 3.4.The detection wavelength was carried out at 228 nm. The method was linear over the concentration range for metformin 50-100 μg/mL and for pioglitazone 20-180 μg/mL. The recoveries of metformin and pioglitazone were found to be 100.5 and 98.7% respectively. The validation of method was carried out utilizing ICH-guidelines. The described HPLC method method was successfully for the analysis of pharmaceutical formulations containing dosage form.

Isocratic Mode

A new, simple, precise, accurate and reproducible RP-HPLC method for simultaneous estimation of Amitriptyline and Perphenazine in bulk and pharmaceutical formulations was developed. Separation of Amitriptyline and Perphenazine was successfully achieved on Inertsil ODS (250x4.6mm) 5µm column in an isocratic mode utilizing Methanol: ACN: Water (50:30:20) at a flow rate of 1.0 ml/min and eluents were monitored at 253nm with a retention time of 2.440 and 5.503 minutes for Amitriptyline and Perphenazine respectively. The method was validated and it was found to be linear. The values of the correlation coefficient were found to 0.992 for Amitriptyline and 0.9992 for Perphenazine respectively. The LOD for Perphenazine and Amitriptyline were found to be and 33.8µg/ml and 4.2 µg/ml. The LOQ for Perphenazine and Amitriptyline were found to be 20.88µg/ml and 12.12µg/ml respectively. The percentage recoveries for Amitriptyline and Perphenazine were found to be within the limit indicates that the proposed method is highly accurate. The method was extensively validated according to ICH guidelines.
