ANALYTICAL METHOD DEVELOPMENT AND VALIDATION FOR THE QUANTITATIVE ESTIMATION OF TRAZODONE IN BULK FORM AND MARKETED TABLET DOSAGE FORM
Jabeen*, A. Rajamani and Dr. A. Yasodha
The present work includes a simple, economic, rapid, accurate and precise isocratic RP-HPLC method development for estimation of Trazodone in bulk form and its marketed formulation. Estimation was done at 286nm which was found to be λmax of Trazodone. The simple, selective, isocratic RP-HPLC method for Trazodone was developed on Phenomenex Luna (C18) RP Column; 250 mm x 4.6 mm, 5μm with a mobile phase of Phosphate Buffer (pH-4.6) and Methanol were taken in the ratio of 65:35% v/v at a flow rate of 1.0 ml/min and detection wavelength 286nm. The developed method was validated successfully according to ICH Q2 (R1) guidelines. The chromatographic methods showed a good linear response with r2 values of 0.9995. The percentage relative standard deviation for method was found to be less than two, indicating that the methods were precise. The mean percentage recovery was for RP-HPLC method was 100.437%. From the results it could be concluded that both the developed method was specific, selective and robust. The method could be successfully applied for analysis of Bulk form and Marketed formulation of Trazodone.
