“…Herein, it can be briefly stated that CP-ISE configurations dominate for the latter -for various drug compounds [311][312][313][314][315][316][317][318]. Their composition [311][312][313][314][315] usually follows traditional basic principles described in the previous reviews [319,320] and, analogously, they are often applied in both direct potentiometric measurements and potentiometric ionpair formation-based titrations. Moreover, enantioselective potentiometric sensors based on carbon paste impregnated with various cyclodextrins were described [316][317][318]321].…”

Abstract:In this review (with 500 refs), both electrochemistry and electroanalysis with carbon paste-based electrodes, sensors, and detectors are of interest, when attention is focused on the research activities in the years of new millennium. Concerned are all important aspects of the field, from fundamental investigations with carbon paste as the electrode material, via laboratory examination of the first electrode prototypes, basic and advanced studies of various electrode processes and other phenomena, up to practical applications to the determination of inorganic ions, complexes, and molecules. The latter is presented in a series of extensive tables, offering a nearly complete survey of methods published within the period of [2001][2002][2003][2004][2005][2006][2007][2008]. Finally, the latest trends and outstanding achievements are also outlined and future prospects given.© Versita Warsaw and Springer-Verlag Berlin Heidelberg.

“…This electrode was modified with silver ethylmercurythiosalicylate (silver thimerosal) and also used as an indicator electrode in the potentiometric titration of thiopental and thimerosal with AgNO 3 . Another modified carbon paste electrode which is selective to piribedil (PD) has been reported from the same author [48]. This electrode was prepared by using piribedil phosphomolybdate as an ion-exchanger.…”

“…A few bioanalytical methods based on spectrophotometry, electrochemical analysis using modified ion‐selective electrodes, capillary electrophoresis, gas chromatography coupled with a nitrogen sensitive detector and another with mass detector, thin‐layer chromatography and HPLC‐UV have been reported in the literature for the quantification of PBD in various biological matrices (Abdel‐Gawad, Issa, Hassouna, & Hussien, ; Abdel‐Hay, Sabry, Barary, & Belal, ; Altiokka, Can, & Aboul‐Enein, ; Fanelli & Frigerio, ; Ibrahim, ; Issa, Abou‐Attia, Abdel‐Gawad, & Abdel‐Hamid, ; Issa, Hassouna, Abdel‐Gawad, & Hussien, ; Jenner, Taylor, & Campbell, ; Sarati, Guiso, Spinelli, & Caccia, ). Spectrophotometric methods lack selectivity while electroanalytical methods are not commonly used in pharmaceutical analysis.…”

Simple, selective and sensitive high-performance liquid chromatographic (HPLC) bioanalytical methods using fluorescence (FL) and photodiode array (PDA) detectors were developed and validated for determination of piribedil (PBD), an anti-Parkinson's drug, in rat plasma and brain samples, with telmisartan as internal standard (IS). Protein precipitation technique was used to extract PBD from both biological matrices. Chromatographic separation was achieved on a Phenomenex Kinetex C end-capped column (250 × 4.6 mm, 5 μm), with 38:62 v/v acetonitrile and ammonium acetate buffer (pH 5.0) as mobile phase at 1.0 mL/min flow rate. Linear response in the concentration ranges 5-300 and 150-3000 ng/mL in plasma, and 15-900 and 450-9000 ng/g in brain tissue were achieved in FL and PDA detectors, respectively. The chromatograms were extracted at 239 nm in case of PDA detection and at excitation wavelength of 239 nm and emission wavelength of 385 nm in case of FL detection. FL detection was found to be more sensitive compared with PDA detection. The developed methods were successfully employed in determining the plasma time course, brain distribution and the pharmacokinetic parameters of PBD following intravenous bolus administration of the drug in male Wistar rats.
