DEVELOPMENT AND VALIDATION OF RP-HPLC METHOD FOR THE ESTIMATION OF TRIFLUSAL IN BULK AND IN CAPSULE FORMULATION

摘要

A simple, rapid, selective and sensitive RP-HPLC method was developed and validated for the estimation of triflusal. The method was carried out using 5-μm particle size, C18-bonded silica column, quaternary pump and acetonitrile: 1 mM potassium dihydrogen phosphate (65:35 v/v) pH 3 as the mobile phase with UV detection at 226 nm. The proposed method is advantageous as it follows isocratic elution in short run time (10 min). The result obtained shown that the method best fits for estimation of drug in capsule formulation and thus can be used for its routine analysis. The newly developed method was validated according to the ICH guidelines with respect to specificity, linearity, accuracy, precision and robustness.
