Summary, etc. |
In this study, four new simple, accurate and highly sensitive spectrophotometric methods have been developed for the determination of Cinitapride (CIN), in both pure and in pharmaceutical preparations. The method M<sub>1</sub> [Metol-Cr (VI)] and M<sub>2</sub> (DMPD – CAT) are direct methods. The method M<sub>3</sub> (NBS/Br-/metol - SA) where the drug is oxidised with excess of N-bromosuccunimide in acid medium, followed by the determination of unreacted N-bromosuccunimide with the dye Celestin Blue and M<sub>4</sub> (EDDP/KIO<sub>3</sub>), where the coloured species formation appears to be due to the formation of coloured charge-transfer complex are indirect methods. Regresion analysis of Beer’s law plots show good correlation in the concentration range of 4.0-16, 2.0-12.0, 4.0-14 and 2-10 µg/mL for methods M<sub>1,</sub> M<sub>2</sub>, M<sub>3</sub> and M<sub>4</sub> respectively, and the corresponding molar absorptivity values are 0.6741 × 10<sup>4</sup>, 3.3708 × 10<sup>4</sup>, 2.5155 × 10<sup>4</sup> and 2.435×10<sup>4</sup> L mol<sup>-1</sup>cm<sup>-1</sup>. All variables have been optimized and the results were statistically compared with those of literature methods by employing the student’s <em>T</em>-test and <em>F</em>-test. No interference has been observed from excipients normally added to the tablets. All the methods are new and superior to the existing methods in terms of λ max and molar absorpitivity. The methods can be applied to the routine pharmaceutical analysis of cinitapride in the formulations. |
