Development And Validation

The present method describes the development of a validated RP-HPLC method for determination of ceftaroline fosamil in presence of its degradation products or other pharmaceutical excipients. The drug substance was subjected to stress conditions of acid, alkali, and oxidative and thermal degradation studies. Separation was carried out on a C-18 X-terra column (Waters Corporation, 250 mm × 4.6 mm I.D.; particle size 5 μm) using 40 : 30 : 30 [buffer : acetonitrile : methanol] as mobile phase at a flow rate of 1.0 ml/min. UV detection was performed at 242 nm. The method was validated with respect to specificity, selectivity, linearity, accuracy, precision, and robustness. The assay method was found to be linear in the range of 40 to 120 μg/mL with a correlation coefficient of 0.9999. The percentage recovery of active pharmaceutical ingredient from parenteral dosage form ranged from 99.5 to 100.2%. The method precision for determination of ceftaroline was below 0.85%. The results showed that the developed RP-HPLC method is suitable for determination of ceftaroline fosamil in bulk as well as stability samples of pharmaceutical dosage forms containing various excipients.

A rapid and precise RP-HPLC method for determination of Olmesartan medoxomil and Hydrochlorothiazide in bulk and pharmaceutical dosage forms. Olmesartan medoxomil & Hydrochlorothiazide are found to be degraded together under different set of conditions as followed according to ICH guidelines and the degradants so formed along with olmesartan & hydrochlorothiazide are separated by using INERTSIL ODS C18 3V (150 x 4.6, 5µ) using mobile phase 1ml triethanolamine in one litre water and the pH was adjusted to 2.5 with orthophosphoric acid and acetonitrile using a gradient program with a flow rate of 1ml/min, throughout the gradient program with a detection wavelength of 225nm for both the compounds with a injection volume of 10µl. The method was validated for selectivity, linearity, accuracy, robustness, precision and specificity. The results were indicating the method was selective in analysis of both olmesartan medoxomil and hydrochlorothiazide in the presence of degradation products formed under various stress conditions.DOI: http://dx.doi.org/10.3329/icpj.v1i11.12058 International Current Pharmaceutical Journal 2012, 1(11): 336-341

Development And Validation

The main objective of the current study was to develop a simple, accurate, precise and rapid RPHPLC method and subsequent validation using ICH suggested approach for the determination of bimatoprost in bulk and pharmaceutical dosage form. The chromatographic separation of bimatoprost was achieved on a phenomenex C18 column (150 mm × 4.6 mm; 5 μm) using PDA detector at 194 nm. The compound was separated with a mixture of acetonitrile and 0.2% triethylamine (pH 7.0 adjusted with o-phosphoric acid) in the ratio of 50:50 v/v as the optimized mobile phase at the flow rate of 1 mL/min. Chromatogram showed peak of bimatoprost at retention time of 3.8 min. The method was validated for linearity, sensitivity, precision, accuracy, system suitability and robustness. Calibrations were linear over the concentration range of 6.25-100 μg/mL as indicated by correlation coefficient (r2) of 0.999. Developed method can be applicable for routine quantitative determination of bimatoprost in pharmaceutical dosage forms.
