AB  - The electrochemical characterization of sertraline at gold electrode was examined by cyclic voltammetry measurements (CV) in pH 8.4 bicarbonate buffer. Then Au electrode was evaluated for the quantitative determination of sertraline using square wave voltammetry (SWV). To enhance the sensitivity during the drug determination, (2-hydroxypropyl)-beta-cyclodextrin (HP beta CD) and beta-cyclodextrin (beta CD) inclusion complexes were employed. Using the proposed SWV technique, the anodic current peak was linear within a concentration range of 0.1-0.5 mu M with a limit of detection (LOD) of 2.0 x 10(-8) M and a limit of quantification (LOQ) of 6.7 x 10(-8) M. In the case of inclusion complex of the sertraline with HP beta CD, a good linearity range of 0.1-0.9 mu M was obtained with a LOD of 2.6 x 10(-8) M and a LOQ of 8.8 x 10(-8) M. The gold electrode revealed the same linearity range for inclusion complex of the sertraline with beta CD with a LOD and a LOQ being 2.6 x 10(-8) and 8.6 x 10(-8) M, respectively. Comparing the regression equations, it can be concluded that the sensitivity in the presence of inclusion complex can be up to 5 times higher. The applicability of the developed method was confirmed by the analysis of this drug in pharmaceutical formulation and in human serum spiked with sertraline standard. The comparison to HPLC method was successfully performed. [GRAPHICS] .

AB  - Esomeprazole has been shown to be the most effective oral PPI for controlling intragastric pH. The persistence of esomeprasole in environmental systems could be solved by different types of its degradation. In this work electrocatalytic degradation of esomeprasole has been investigated in the presence of sodium sulfate and sodium chloride using IrOx electrode and was monitored using UV-Vis spectrophotometer at 303 nm. Also the electro degradation process was examined and on Au electrode. NanoScope III A (Veeco, USA) microscope was used to study the morphology of Esomeprazole on the gold surface by atomic force microscopy. By optical microscopy the
morphology of Esomeprazole dissolved in human serum on the gold surface was studied as well.
