Determination of nitrendipine with beta-cyclodextrin modified carbon paste electrode

Abstract

Carbon paste electrodes modified with beta-cyclodextrin have been investigated for voltammetric determination of nitrendipine. The immobilization of the beta-cyclodextrin on the carbon paste leads to a modification of the electrode surface that causes a significant increase in the peak current of the nitrendipine reduction, probably due to formation of an inclusion complex between beta-cyclodextrin and nitrendipine. This property was used with analytical purpose,,; by developing a stripping differential pulse voltammetric (SDPV) method to determine nitrendipine.
