| Popis: | A reverse phase HPLC method is described for the determination of rosiglitazone and gliclazide in tablet dosage form. Chromatography was carried on Phenomenix Gemini C18 column using in mixture of ammonium phosphate buffer, Acetonitrile and methanol in the ratio 50: 35: 15 v/v as mobile phase at a flow rate 1 mL min-1 and the effluent was monitored at 254 nm. The retention time for rosiglitazone was 3.74 and gliclazide 7.84 min. The limit of detection for rosiglitazone was 4.07μg/mL and gliclazide 1.19 μg/mL. The LOQ obtained for rosiglitazone was 12.33 μg/mL and 3.612 μg/mL. The percentage assay for rosiglitazone was 99.92% and gliclazide was 99.82%. The method was validated for accuracy precision and system suitability. The proposed method was fast accurate and precise so it can be used for regular quality control of the drug. |
