“…It is seen that increasing the pH, the peak current decreases due to pH dependence of half wave potential, which indicates the involvement of protons in the electrode process and finally dislocated in alkaline pH due to a lower number of available protons. 27 It can be seen from Figure 5b that with increase in pH of the solution, the oxidation current was observed to be shifted towards lower potentials.…”

“…The anodic voltammetric signals can be ascribed to the oxidation of −NH group. 27 The electroanalytical performance of TiO 2 NPs/CPE was advantageous over that observed at the bare CPE. The cyclic voltammograms of PRX showed about 2.5 times enhancement in the oxidation peak current at TiO 2 NPs/CPE (165 µA) as compared to a bare CPE (65 µA).…”

In this study, a facile sensor based on TiO 2 nanoparticles modified carbon paste electrode was developed for voltammetric determination of pramipexole in pharmaceutical formulations and biological samples. Surface of the fabricated electrode have been characterized using field emission scanning electron microscopy. Under the optimized experimental conditions, the modified electrode was exhibited excellent electrocatalytic activities and a sensitive oxidation peak at 0.9 V in the phosphate solution of pH 5.0 for electrooxidation of pramipexole. The plot of pH vs. E p generated a slope of 62.5 mV per pH in the pH range of 3.0-13.0 indicating the contribution of an equal number of electrons and protons in the electrode process. A differential pulse voltammetry method was developed in the concentration range of 0.46-100 µmol L −1 with a limit of detection of 0.14 µmol L −1. The proposed method is simple, rapid, and inexpensive and also showed good selectivity and sensitivity toward pramipexole.

“…Various analytical methods have been reported in literature for determination of pramipexole dihydrochloride, including high performance liquid chromatography (HPLC) [2][3][4][5][6][7][8][9][10][11][12], high performance thin layer chromatography [13], liquid chromatography tandem mass spectrometry [14,15], gas chromatography mass spectrometry GC/MS [16], spectrophotometry [17][18][19][20][21][22][23][24], and potentiometry [25,26]. Recently, voltammetric determination of this drug using glassy carbon electrodes was reported [27][28][29][30]. The present work aimed to study the voltammetric behaviour and make an assay with pramipexole dihydrochloride at carbon paste electrode, using cyclic and differential pulse voltammetry.…”

The electrochemical behavior of pramipexole dihydrochloride was studied at carbon paste electrodes in 0.04 M Britton-Robinson buffer of pH 6.08, using cyclic and differential pulse voltammetric techniques. The oxidation of pramipexole dihydrochloride is an irreversible diffusion-controlled process. A differential pulse anodic voltammetric procedure has been developed for determination of the drug over the concentration range of 1.20 -8.23 μg/mL, with detection and quantification limits of 0.21 and 0.68 μg/mL, respectively. The proposed method was successfully applied for the determination of the drug in its commercial tablets.

A voltammetric sensor is an effective tool for pharmaceutical analysis due to its simplicity, specificity, sensitivity, fast, cost-effectiveness, and repetitive measurements. A highly sensitive and selective sensor is fabricated based on a polyaniline-modified glassy carbon electrode. It is demonstrated that this sensor can be used for the determination of a pharmaceutically important compound tinidazole using square wave voltammetry, cyclic voltammetry, and electrochemical impedance spectroscopy. The electrode surface was characterized by scanning electron microscopy. The developed sensor also exhibited good reproducibility and long-term stability. Polyaniline nanofibers are expected to be a promising material for sensing applications because of the ease of fabrication, excellent electrochemical performance, and high electroactive surface area.
