stability indicating method

This paper portrays the advancement and approval of a solidness showing fluid chromatographic strategy for measure of desvenlafaxine in unadulterated and in plans utilizing X-Terra RP C18, 250x4.6 mm, 5 µm particle size column with detection at wavelength 226nm. In the present investigation the mobile phase comprising of sodium dihydrogen orthophosphate buffer (pH 4.0) and acetonitrile in the proportion of 60:40%/v with the Flow rate of 1.0ml/min and column temperature at surrounding temperature uncovered the better resolution and affectability for desvenlafaxine. The maintenance time of desvenlafaxine peak was about 3.632min independently. The created approach be accepted according to ICH regulations which incorporate framework appropriateness, particularity, linearity, exactness, accuracy, vigor, toughness, affectability, cutoff of detection and measurement contemplates and the outcomes were incorporated in this paper. Keywords: Desvenlafaxine, stability indicating method, RP-HPLC, ICH regulations.

Analysis of pharmaceutical and neutral compound and newer drugs commonly used in all the stages of drug discovery and development process. High performance thin layer chromatography (HPTLC) is one of the easiest instrumental technique based on the full capabilities of thin layer chromatography.it is still increasingly finding its way in pharmaceutical analysis with the advancements in the stationary phase and the introduction of the densitometers as detection equipment and the technique achieves high precision and trueness comparable to high performance liquid chromatography (HPLC).

Simple, accurate and stability-indicating reversed phase high performance liquid chromatographic method was developed and validated for the determination of Eperisone HCl using a Phenomenex Luna C18 (250 x 4.6 mm)  5μm column and a mobile phase of buffer and methanol in the proportion of (30:70) pH 3.0 adjusted with o-phosphoric acid. The retention time of Eperisone HCl were found to be 9.050min respectively. Linearity was established for Eperisone HCl in the range of 50.25 to 150.75µg/ml, respectively. The percentage recovery of Eperisone HCl was found to be in the range of 98.96-99.68% respectively. The selected drug were subjected to acid, alkali and neutral hydrolysis, oxidation, dry heat, photolytic and UV degradation and the degradation studies revealed, Eperisone HCl is well resolved from the pure form with significant differences in their retention time values. This method can be successfully employed for the quantitative analysis of Eperisone HCl in pure and formulation.
