METHOD DEVELOPMENT AND VALIDATION OF LIRAGLUTIDE IN BULK AND MARKETED DOSAGE FORM BY USING RP-HPLC TECHNOLOGY Enhancing Quantitative Analysis through RP-HPLC Technology
Main Article Content
Abstract
Simple, Precise, Economical, Fast and Reliable RP-HPLC Technique has been developed for the estimation of Liraglutide in bulk and pharmaceutical dosage form. The detection was carried out by using a UV detector set at a wavelength of 245nm and 20μl sample was injected. The retention time for Liraglutide was 2.978 min. The peak obtained was symmetrical with tailing factor less than 2 and theoretical plates more than 2000. Isocratic elution at a flow rate of 1.2ml/min was employed on Inertsil ‐ Extend ‐ C18 (250 × 4.6 mm, 5 μm) HPLC column. A mobile phase comprising PHP Buffer (0.1% OPA): MeOH: ACN 50:25:25%V/V (pH 4.2) was developed. Validation experiments were performed to demonstrate linear over the concentration range of 10 ‐ 100μg/ml and get the correlation Regression (r2) 0.9996, showed good recoveries 98.95 - 101.22 %, the % RSD of Precision studies were found ˂ 2%. The method can be used for quality control assay of Liraglutide. The results were validated statistically as per ICH Q2 R1 guideline and were found to be satisfactory. The proposed methods were successfully applied for the determination of Liraglutide in commercial pharmaceutical dosage form.
