Abstract

Abstract A rapid isocratic reversed-phase HPLC method for the determination of the major component of teicoplanin in plasma is described. By using solid phase extraction C18 and UV detection at 240 nm, this method is specific, and sufficiently sensitive. We found a good linearity over the range: 5 – 40 mg/1 of teicoplanin plasma concentrations. The coefficients of variation did not exceed 5.4% both within-day and between-day assays. With the small plasma sample required for the analysis (250 μl) and the good accuracy, this rapid procedure appears to be suitable for the therapeutic drug monitoring.
