Abstract: | The aim of the present study was to develop and validate an analytical method for the estimation of nepafenac as a raw material as well as in dosage form (suspension) by using reverse phase high performance liquid chromatographic (RP-HPLC). The target was to obtain an easy, rapid, reproducible as well as a rugged ethod. The HPLC system that was used in the proposed study was LC-20AD liquid chromatograph equipped with SPD-20A UVVIS detector. The separation was performed on C18 column which was attached with loop 20µl. lution was done at ambient temperature with a mobile phase consisting of acetonitrile: Water (40: 60v/v) at a flow rate of 1ml/min and at a wavelength of 254 nm. The proposed method was validated as per the ICH guidelines. The retention time for nepafenac was 7.49 minutes (% CV=0.0076). The percentage coefficient variation (CV) of six consecutive peak areas of injections was 0.34% with tailing factor 1.76. The peak area responses were linear within the concentration range of 0.078- 20.0µg/ml (R2 =0.9993). The sensitivity of the method could be evaluated by limits of detection (LOD) (0.0195µg/ml) and limits of quantitation (LOQ) .039µg/ml). Nepafenac drug is s in its diluent that could see by intra-day (% CV =0.45-1.96) and inter-day variation (%CV=0.173-1.898%). The accuracy and recovery results of 80%, 100% and 120% were 97.40% to 102.10% with % CV of 0.3201% to 1.3496%. The robustness and ruggedness of the method are significantly broader and is reproducible. It could be used as a more convenient, efficient, easy and time saving method for the analysis of drug in raw material as well as in dosage form (ophthalmic suspension). |
