A simple, rapid, and precise RP-HPLC method for simultaneous analysis of atorvastatin calcium, metformin hydrochloride, and glimepiride in bulk and its pharmaceutical formulations has been developed and validated. These drugs were separated by using Grace Smart Altima C-8 column (250 × 4.6 mm, 5-μm) with a mobile phase consisting of acetonitrile : phosphate buffer (60 : 40 (v/v), pH 3.0) at a flow rate of 1 mL/min, injection volume 25 µL, and detection at 235 nm. Metformin, atorvastatin, and glimepiride were eluted with retention times of 2.57 min, 7.06 min, and 9.39 min, respectively. The method was validated for accuracy, precision, linearity, specificity, and sensitivity in accordance with ICH (Q2B) guidelines. The results of all the validation parameters were found to be within the acceptable limits. The calibration plots were linear over the concentration ranges from 10 to 150 µg/mL, 20 to 200 µg/mL, and 10 to 150 µg/mL for atorvastatin, metformin, and glimepiride, respectively. The accuracy and precision were found to be between 98.2%–105% and ≤2% for three drugs. Developed method was successfully applied for the determination of the drugs in tablet dosage form and recovery was found to be >98% for three drugs. The degradation products produced as a result of stress studies did not interfere with drug peaks.

Objective: To develop an accurate, simple, rapid, precise, economic and stability indicating RP-HPLC method for the simultaneous estimation of dosulepin hydrochloride and methylcobalamin in tablet dosage form and validate as per ICH guidelines.Methods: The column used was Kromasil C18 (250 X 4.6 mm, 5 µm), with a mobile phase containing acetonitrile: phosphate buffer pH 3 adjusted with o-phosphoric acid (60:40) with a flow rate of 1 ml/min. The effluents obtained were monitored at 285 nm with photodiode array detector. Dosulepin hydrochloride and methylcobalamin were subjected to stress degradation conditions like hydrolysis (acid and base), oxidation, thermal and photolysis degradation. The samples subjected to stress degradation were analysed by the developed method.Results: The retention time for dosulepin hydrochloride and methylcobalamin was found to be 7.99 min and 1.97 min, respectively. The linearity of developed method was achieved in the range of 165-495 μg/ml for dosulepin hydrochloride and 5-15 μg/ml for methylcobalamin. The detection (LOD) and quantitation (LOQ) limits were found to be 0.75 µg/ml and 2.28 µg/ml for dosulepin hydrochloride and 0.040 µg/ml and 0.121 µg/ml for methylcobalamin respectively. In the stability studies, it was observed that there is no interference of the degradation products with drug samples.Conclusion: An accurate simple, rapid, precise, linear and stability indicating RP-HPLC method was developed for simultaneous quantitative estimation of dosulepin hydrochloride and methylcobalamin both in bulk and pharmaceutical formulation. The method was validated as per ICH guidelines. This method holds good for the routine analysis of dosulepin hydrochloride and methylcobalamin in various pharmaceutical industries as well as in academics.

A rapid, precise, accurate, specific and simple stability indicating RP-HPLC method was developed for simultaneous estimation of Dapagliflozin Propanediol (DAPA) and Metformin Hydrochloride (MET) in its tablet dosage form. Method was performed on a column C8 Thermoquest, hypersil division of dimension 250 mm × 4.60 mm having particle size 5 micron. The mobile phase used in the method was 10 mM Ammonium Acetate buffer (pH- 4), Methanol and Acetonitrile in proportion of 30:65:05 respectively. The drug was subjected to acid and alkali hydrolysis, oxidation, photolysis and heat as stress conditions. The method was validated for specificity, linearity, range, precision, accuracy, robustness, LOD, LOQ and system suitability. The flow rate was maintained at 0.8 ml/ min and effluent was monitored at 227 nm. The retention time were observed 5.988 min and 4.661 min for DAPA and MET respectively.  The standard curve was found linear over range of 60-140 μg/ml for DAPA and 300-700 μg/ml for MET with correlation coefficient of 0.9996 for DAPA and 0.9994 for MET. The limit of Detection (LOD) of this method was 1.121 μg/ml for DAPA and 6.162 μg/ml for MET. The limit of Quantitation (LOQ) of this method was 3.396 μg/ml for DAPA and 18.674 μg/ml for MET.  The percentage recovery was found to be in the range of 98-102% at three different levels of a standard addition. The precision (repeatability, intra-day and inter-day) of the method was within the limit (RSD<2%). Degradation products produced because of stress studies did not interfere with the detection of DAPA and MET and the assay can thus be considered stability-indicating. Combination tablet was successfully analysed using the developed method.
