AB  - Duloxetine hydrochloride ( D U L ) , a naphth) I ether amine, inhibits the
uptake of serotonin and norepinephrine. The electrochemical behavior of D U L
was determined by cyclic voltammetry ( C V ) in phosphate buffer solution at gold
electrode by varying pH and scan rate. The electroanalytical application was
studied with the aid of differential pulse voltammetry (DPV) in sodium
bicarbonate solution. A linear response ranged from 5x10'^ M to 10'" M. The
validation of the DPV method was carried out by determine of the limit of
detection (LOD) and limit of quantitation (LOQ) and the calculate values were
4.6 X 10"'' and 2 x 10'^' M, respective!). The proposed DPV method has been
successfully applied to assessment DUL as standard and in Taita® tablets and
standard spiked with human serum.

AB  - Ticagrelor hydrochloride (TCG) is effective in platelet inhibition and useful for preventing cardiovascular death, myocardial infarction, or ischaemic stroke. The drug standard was investigated by cyclic voltammetry (CV) and quantitatively determined using differential pulse voltammetry (DPV) via its electrooxidation at Au electrode in 0.05 M NaHCO3. DPV showed a linear dependency of the anodic peak currents vs. TCG standard concentrations in the range from 3 x 10-7 mol l-1 to 10-5 mol l-1 with the values of the limit of detection (LOD) and the limit of quantification: 0.288 μmol l-1 and 0.96 μmol l-1, respectively. Using the constructed and validated calibration curve, the values of unknown ticagrelor concentrations in Ticagrex® tablets and in human serum spiked with the standard were determined. Mechanistic study suggests that the oxidation proceeds at sulfur atom by removal of one electron as the rate determining step. In the next, fast step, formed radical cation loose another electron and sulfoxide is formed (with water molecule as nucleophile). The study of TCG degradation showed that at the Au, after 4.5 h of potential cycling, degradation occurs, which was confirmed by UV spectroscopy.

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.
