Abstract

A simple, accurate, rapid and precise reverse phase high performance liquid chromatographic method was developed for simultaneous estimation of Irbesartan and Atorvastatin in synthetic mixture. Inertsil C18, 150 mm x 4.6 mm, 5 μm particle size in gradient mode with mobile phase Acetonitrile: 0.1% Formic acid (40: 60 v/v) and pH adjusted to 3.5 ± 0.1 with orthophosphoric acid was used. The flow rate was 1.0 ml/min and absorbance of individual component was measured at 262 nm. The retention times of Irbesartan and Atorvastatin were found to be 3.993 and 7.733 min, respectively. Linearity for Irbesartan and Atorvastatin was in the range of 400 - 800 and 50- 100μg/ml with correlation coefficient values 0.9995and 0.9994, the percentage recovery obtained was 99.88and 99.70 %, respectively.

Abstract

A new simple, economical, precise and accurate method are described for the simultaneous determination of Nifedipine (NIF) and Metoprolol Succinate (MET) in combined tablet dosage form. The proposed method was applied for the determination of Nifedipine and Metoprolol Succinate in synthetic mixture, for determination of sampling wavelength, 10μg/ml of each of NIF and MET were scanned in 200-400 nm range and sampling wavelengths were 313nm for NIF and 275.40nm for MET are selected for development and validation of absorption correction method. For this method linearity observed in the range of 5-25μg/ml for NIF and 25-125μg/ml for MET, and in their pharmaceutical formulation with mean percentage recoveries 100.68 and 100.33, respectively. The method was validated according to ICH guidelines and can be applied for routine quality control testing.
