Adsorptive stripping voltammetric determination of antihypertensive agent: diltiazem

Voltammetric sensor based on Co3O4/SnO2 nanopowders for determination of diltiazem in tablets and biological fluids

“…Various analytical methods have been employed for this purpose, e.g. high-performance liquid chromatography in human cardiac tissue [7], in blood [8] and in human plasma [9][10][11][12][13], high-performance thin-layer chromatographic [14], gas chromatography [15], spectrophotometry [16,17], liquidsolid extraction [18] and voltammetry [19]. Since employed techniques for determination of diltiazem in the presence of other drugs are mostly spectroscopy and HPLC, and these methods often are complex and consuming cost solvents, must easy-handled and simple-operating methods need be applied.…”

In most cases, synergistic eff...…”

A novel potentiometric sensor based on ZnO decorated polyaniline/coal nanocomposite for diltiazem determination

“…2 As a result, it is essential to closely monitor the DTZ level in pharmaceutical doses and biological fluids when using this medication. It has been reported that DTZ can be detected in its solutions using a variety of analytical techniques, including high performance liquid chromatography (HPLC), 3 gas chromatography, 4 high performance thin layer chromatography (HPTLC), 5 spectrophotometry, 6 voltammetry 7–9 and potentiometry. 10 Most of the aforementioned techniques have plenty of limitations, including the requirement for expensive equipment, the need for earlier time-consuming treatment or derivatization reactions and their inapplicability to colored and turbid drug sample solutions.…”
