摘要
The anodic voltammetric behavior of tiapride hydrochloride (TiapCl) was studied at carbon paste electrodes in 0.04 M Britton-Robinson buffer pH 7.0 using cyclic and differential pulse voltammetric techniques. The oxidation of TiapCl is an irreversible diffusion-controlled process. A differential pulse anodic voltammetric procedure has been developed for determination of the drug over the concentration range 0.36 - 19.35 mu g/ml with detection and quantification limits of 0.12 and 0.40 mu g/ml, respectively. The proposed method was successfully applied for the determination of the drug in commercial tablets and in spiked human urine samples.
