Bio-Analytical Method Development of Repaglinide Drug Delivery Systems
A sensitive, specific and rapid high-performance liquid chromatography-ultraviolet spectroscopy method was developed and successfully validated to estimate the repaglinide in rabbit plasma. The solvent extraction method was used for repaglinide from serum by using ethyl acetate and 0.1N HCl. The mobile phase consists of acetonitrile: phosphate buffer pH 4.0 at 60:40 %v/v with 1% triethylamine at flow rate of 0.8ml/min and at fixed wavelength of 254nm. On ten minutes of run time, repaglinide was retention at 7.4min. The extraction efficiency 95% for repaglinide. The intra-day and inter-day precision was in the terms of %RSD less than 1.76%. The developed method was validated and proposed method is useful for pharmacokinetics studies.
