ABSTRACT In this study, reversed phase high performance liquid chromatographic method have been developed and validated for the simultaneous determination of ibuprofen and famotidine in combined pharmaceutical formulation. In RP-HPLC method, optimization of chromatographic parameters was done. Optimization conditions was found to be 0.1% orthophosphoric acid (pH-3), acetonitrile in 50:50 v/v ratio as mobile phase at a flow rate of 0.8 mL/min. The peaks were well resolved with C18 column (46mm x 150mm , 5um) with a retention times 2.473 and 3.407 min for ibuprofen and famotidine respectively. UV detection was performed at 231 nm. The responses were linear (R2 > 0.9999) in the range of 80 – 400 μg/ml for ibuprofen and 2.6 – 13 μg/ml for famotidine. The % recovery for ibuprofen and famotidine was found to be 100.7 and 98.3 respectively. LOD and LOQ was found to be 0.121 μg/mL, 0.404 μg/mL for famotidine and 3.332 μg/mL, 11.1 μg/mL for ibuprofen respectively. No chromatographic interference from the tablet excipients was found. The results of the studies showed that the proposed RP-HPLC method is simple, rapid, precise and accurate, which can be applied for the routine analysis of ibuprofen and famotidine in tablet dosage forms. Keywords: High performance liquid chromatography, validation, ibuprofen, famotidine and tablet dosage form. [Download Article] [Download Certifiate] |
