Abstract
A simple and sensitive High-Performance Liquid Chromatography (HPLC) method with fluorescence detection for quantitation of telmisartan in rabbit plasma was developed and validated. Separation of telmisartan from plasma components was achieved on a Chromolith RP18e column (100 x 4.6 mm 5 μ). Losartan was used as an internal standard. A mobile phase consisting of 50 mM sodium phosphate buffer and acetonitrile in the volume ratio of 65:35 v/v was delivered at a flow rate of 3.5 mL/min. A simple and rapid sample preparation involved solid phase extraction using Varian Bond Elute C-18 cartridge. The linearity range of the proposed method was 4 to 375 ng/mL. The intra-day and inter-day coefficients of variation obtained for telmisartan were less than 4.90% and relative error was less than 9.08%. The overall recoveries for telmisartan and losartan were 101.7% and 100.0%, respectively. This validated method was used successfully for analysis of plasma samples from a pharmacokinetic study.
