Abstract

Objective: A fast, specific, and sensitive high-performance liquid chromatographic method has been developed and validated for the quantitative determination of unchanged Ramipril (RAM) and Telmisartan (TEL) in animal plasma.

Methods: Analytes were extracted from animal plasma, 250 µl of animal plasma sample were mixed with internal working standard (25 ngmL-1) with the further addition of chloroform (HPLC Grade, Merck). The clear organic layer was separated and reconstituted to 1 ml in mobile phase and analysed by HPLC. The method was validated and evaluated in terms of linearity, accuracy, precision, specificity, limit of detection and limit of quantitation.

Results: Absorption maxima of TEL and RAM was found to be 270 and 273 nm respectively. TEL and RAM with their respective internal standards (I. S.) were found to be well separated from the co-eluted components and there were no interferences from the endogenous material. The limit of detection (LOD) and limit of quantitation (LOQ) were found to be 2.01±.05; 4.88±0.10 and 0.11 and 0.25 for TEL and RAM respectively on the basis of a signal to noise ratio. The ruggedness of the method at various parameters was found to be±1.94% and±1.02% for TEL and RAM respectively. The low values of %RSD (<2.0) for each of the drug proposed that during all deliberate variations, middle-quality control (MQC) was not affected and it was in accordance with that of actual.

Conclusion: Thus developed High-Performance Liquid Chromatography (HPLC) method was found to be more accurate, precise, sensitive, selective and reproducible.
