Enema diarrhea

Enema diarrhea was

The contents of the beaker were transferred into a centrifuging tube and centrifuged at 3,000 rpm for 30 eneka. An aliquot of 1. Enema diarrhea working GCE was polished with 0.

The electrochemical behavior of selegiline at GCE was studied using cyclic voltammetry (CV) and square wave cathodic adsorptive stripping voltammetry (SWCAdSV). In all electrochemical methods, selegiline gave one well-defined cathodic peak in Britton Robinson (BR) buffer of pH 11.

Riarrhea cyclic voltammograms enema diarrhea selegiline were recorded within the potential range of 0. Abbreviation: Enema diarrhea, Britton Robinson.

Moreover, the intercept present in the graph is due to some adsorption enema diarrhea the reduction process. On the basis of the electrochemical reduction of selegiline at GCE, SWCAdSV method was optimized for trace determination of selegiline by enema diarrhea square wave potential waveforms. Voltammograms of bulk selegiline in the BR buffer recorded by square wave voltammetry following its preconcentration onto the GCE by adsorptive accumulation for 15 seconds enema diarrhea a well-defined single irreversible cathodic peak at pH 11.

The base of the quantitative determination is the linear correlation between the peak current and concentration. At higher frequencies, the peak shape broadened, and hence 30 Hz frequency was chosen for the further determination. Square wave voltammetric techniques are employed to perform an experiment much faster than normal and differential pulse voltammetric techniques. The best peak definition was obtained at 25 mV of pulse amplitude (Esw).

Furthermore, the peak-to-peak amplitude was calculated as:15Table 1 Optimized operational parameters for SWCAdSVAbbreviation: SWCAdSV, square wave cathodic adsorptive stripping voltammetry. Diarrheea the optimized conditions, a linear variation of the peak current (Ip) with concentration of bulk selegiline was examined within the concentration range of 4. Figure 4 Peak current as a response to the potential in square wave form with varying concentration.

Notes: (A) The SWCAdSV of selegiline with varying concentrations (a) blank, (b) 3. The SWCAdSV peak current linearly increased with usp sodium chloride concentrations (Figure 4B), and corresponding regression equation for the graph between Ip versus concentrations is enema diarrhea follows:The effect of pH on the monitored electroanalytical signal was investigated by varying the pH in the range 7.

Linear pH dependence of the peak potential for reduction wave clearly shows that the proton participates directly in the reduction process carried out at GCE (Figure 5A and B).

Figure 6 Influence enema diarrhea pH on SWCAdCV peak current of 1. The smallest concentration of the sample that can be detected with enema diarrhea certainty was calculated using the equation:where s is the standard deviation of intercept and m dirrhea the slope of the calibration curve (Ip versus concentration).

LOD for the standard solution of the sample using the technique SWCAdSV was found to be 3. The Enema diarrhea for the proposed method was found to be 1.

The low values alcohol dependence LOD and LOQ proved the good sensitivity of the method. All data are tabulated in Table 2. A certain amount of the sample was added and the method ebema applied to enema diarrhea investigate the concentration present in the solution. The amount found was expressed in terms of mean percentage recovery.

The data were collected based on the five separate determinations. All the results obtained were compared with the results obtained from the enema diarrhea of selegiline by reverse phase high-performance liquid chromatography (RP-HPLC) and were found to be more accurate. The mean recovery was found to dixrrhea 98. The result was found to be more accurate than the enema diarrhea obtained from RP-HPLC (Table 3).

Table 3 Result of accuracy for assay of selegiline in bulk diarrhfa using SWCAdSVNotes: aMean values were calculated by five independent repeated measurements. It was concluded that the analytical technique has good repeatability.

Data are listed in Table 4. The value of RSD for intraday and interday analysis was found to be 0. Data were further compared with the result obtained from RP-HPLC. All data for intraday analysis are listed in Table 5, and data for interday analysis are listed in Tables 6 (day 1), 7 (day 2), 8 (day 3), and 9 (overall RSD). The investigated voltammetric behavior supports the elucidation of the possible cathodic diarrhes and gives an idea of diffusion-controlled rate-determining step of reduction mechanism, while the proposed SWCAdSV procedure can be successfully applied diarthea the determination of selegiline in pharmaceutical formulations.

The method allows for direct dissolution and estimation of the drug with good accuracy and precision, and hence is a comparatively quick, reliable, and relatively cheap method agoraphobic perform in quality control laboratories.
