“…A comparison between the analytical parameters of the suggested sensor and a few electrochemical electrodes reported in the literature for the DIP determination are given in Table 5. 1,3,16,17 In this study, we conducted a comparison analysis of DIP using the potentiometric method with previous methods, such as differential pulse voltammetry and stripping voltammetry. The comparison results of these methods showed that each method has advantages and disadvantages.…”

A dipyridamole (DIP) based surface molecularly imprinted polymer (MIP) was synthesized and applied as a sensing agent in a sensing layer of a new modified potentiometric carbon paste electrode (CPE). The potentiometric modified CPEs (GO@SiO 2-NH 2-MIP/MWCNTs/CPE, where GO is graphene oxide and MWCNTs is multi-walled carbon nanotubes) showed an improved performance in term of Nernstian slope, selectivity and response time compared to the unmodified CPE. The response time of the sensor in the range of 2.5 × 10-8-1.1 × 10-2 M DIP was 20 s. The obtained DIP sensor showed low limit of detection (1 × 10-8 M), and satisfactory long-term stability (higher than 4 months). The practical application of the sensor was demonstrated by the determination of DIP concentration in urine samples and pharmaceutical preparations, with good precision and acceptable recoveries (96.0-103.0%). The prepared sensor showed high selectivity for DIP over a number of common species (aspirin, caffeine, ascorbic acid, glucose, urea, bipyridine,

“…Recently, we used modified CPEs for trace analysis of some drugs and heavy metals in various environments [20][21][22][23][24]. Newly we showed that the application of nanopowders of Fe 2 TiO 5 in CPEs catalyses the oxidation of salbutamol and enhances the peak current values in the differential pulse anodic stripping voltammetric (DPASV) determination of it at sub-nanomolar levels [25].…”

In this work, an anodic stripping voltammetry for nanomolar determination of diltiazem with a chemically modified carbon paste electrode (CMCPE) containing Co 3 O 4 / SnO 2 nanopowders was studied. The accumulation potential and time were selected at, -0.2 V and 190 s, respectively. The electroanalytical performance of the CMCPE was evaluated regarding the carbon paste composition, the solution pH, the time and potential accumulation, and the potential interferences. The novel electrode showed linear response to diltiazem concentration range of 50-650 nM with a lowest detection limit value of 15 nM. The precisions for six consecutive determinations of 350 and 550 nM diltiazem were 3.2 and 2.5 %, respectively. It was demonstrated that the proposed method was free from most interference. Finally, the method was effectively applied to the determination of diltiazem in pharmaceutical tablets and biological samples.

“…DIP's electrochemical (cathodic [1] and anodic [2,3,27,28]) behavior was investigated in aqueous [1,27], micellar [28], and nonaqueous media [2,3] at different electrodes, e.g., Pd [3], Pt [2,3,27], mercury-coated platinum microelectrode [1], glassy carbon, and graphite [28]. On the other hand, there are few literature reports related to voltammetric methods developed for DIP quantification in pharmaceutical [14,[29][30][31] and biological samples [14,15,31,32].…”

The present paper describes the voltammetric analysis of dipyridamole (DIP) at a cheap, disposable pencil graphite electrode (PGE). The working conditions were optimized with regard to the electrode material and the supporting electrolyte. Cyclic voltammetric investigations emphasized that DIP is irreversibly oxidized at the PGE. The electrode process is pH-dependent and controlled by both diffusion and adsorption. For DIP quantitative determination a differential pulse voltammetric (DPV) method in phosphate buffer solution pH 7.00 was developed. DIP's oxidation peak current varied linearly with the analyte concentration, presenting two linear ranges, namely 5.00 × 10 −7-2.50 × 10 −5 M and 2.50 × 10 −5-2.50 × 10 −4 M, with detection and quantification limits of 1.21 × 10 −7 M and 4.03 × 10 −7 M DIP, respectively. The newly developed DPV method using the inexpensive, disposable PGE was successfully applied for the simple and rapid determination of DIP from pharmaceutical formulations.
