Liquid Chromatographic

The intention of this work is to develop a rapid, precise, accurate and sensitive reverse phase liquid chromatographic technique for the simultaneous estimation of Nebivolol and Valsartan in tablet dosage form. The chromatographic method was standardized using Inertsil ODS column (250×4.6mm, 5μm particle size) with UV detection at 278nm and flow rate of 1ml/min. The mobile phase comprises of ACN: Buffer (pH adjusted to 3.5 with dilute Ortho Phosphoric acid) in the fraction of 60:40 v/v. The linearity of proposed method was investigated in the range of 12.5-62.5μg/ml (R²=0.999) for Nebivolol and 200-1000μg/ml(R²=0.999) for Valsartan duly. The limit of detection (LOD) was found to be 0.05μg/ml and 0.81μg/ml for Nebivolol and Valsartan duly. The limit of quantification (LOQ) was found to be 0.15μg/ml and 2.44μg/ml for Nebivolol and Valsartan respectively. The retention time of Nebivolol and Valsartan were ground in to be 4.400min and 2.568min respectively. The method was authentically suggested and % RSD was ground in to be less than 2 indicating high degree of accuracy and precision.

A simple, fast, accurate and precise reverse phase HPLC method is developed and described for the determination of ramelteon in tablet dosage form. Chromatography was carried on an ODS column using a mixture of acetonitrile and phosphate buffer pH 7.0 (35:65 V/V) as the mobile phase at a flow rate of 1.0 mL/min with detection at 286 nm. The retention time of the drug was 7.7 min. The procedure was validated for linearity, precision, accuracy, and robustness. The developed method was validated for linearity from 50 to 150% which shows the method is quite linear with a correlation coefficient of 0.999, for precision which includes system precision, method precision, intraday and by another analyst on another day, and accuracy. The %RSD for system precision was observed to be 1.1, whereas the method precision was observed to be 0.2. The % recovery from ‘accuracy’ studies yielded the recovery of 99.7-101.5% which indicates the capability of the method, and finally for robustness that includes studies w.r.t. change in flow rate, the percentage of organic modifier and pH.
