Abstract:
A precise, sensitive and quick High Performance Liquid Chromatographic (HPLC) method for the determination of rosuvastatin calcium in bulk and tablet dosage forms has been validated. The chromatographic scheme involved: Sil-20A auto sampler, LC-20A pump, SPD-20A UV/visible detector with separation attained by C18 column at 40ºC temperature through a mobile phase of acetonitrile and buffer (50:50) at a flow rate of 1.0ml/min. The method is precise (%RSD for intra-day and inter-day extended between 1.06-1.54% and 0.103-1.78%) and linear (r2=0.9997). Limit of detection and quantification (LOD & LOQ) of the adopted method were 0.78 and 1.56μg/ml. The proposed HPLC method was established to be sensitive, precise and swift that can be proficiently adopted in quality control/quality assurance laboratories for predictable investigation of the bulk and oral solid dosage forms of rosuvastatin calcium.
