DEVELOPMENT AND VALIDATION OF NEW RP-HPLC METHOD FOR THE ESTIMATION OF LINEZOLID IN LINEZOLID GEL
Journal Title: International Journal of Pharmacy and Pharmaceutical Sciences - Year 2015, Vol 7, Issue 4
Abstract
Objective: Development and validation of new RP-HPLC method for the estimation of linezolid in linezolid gel.Methods: Linezolid was chromatographed on a reverse phase symmetry C18 column (150 x 4.6 mm x 3.5 µm) in a mobile phase consisting of potassium dihydrogen phosphate buffer (pH 4.6 adjusted with 10% orthophosphoric acid) and methanol in the ratio of 55:45. The mobile phase was pumped at a flow rate of 1.2 ml/min with detection at 250 nm.Results: The retention time for Linezolid was found about 2.94 min. The detector response was linear in the concentration of 20 µg/ml to 160µg/ml with correlation coefficient of 0.9997. The percentage recovery of Linezolid at target concentration was found to be 97.8%. The limit of detection and limit of quantification was found to be 10 μg/ml and 5 μg/ml respectively. All other validation parameter were within acceptance criteria.Conclusion: The proposed method was found to be simple, fast, accurate, precise and reproducible and could be used for routine quality control analysis of Linezolid in Linezolid gel.Â
