Development And Validation

The present work described the development of two simple, accurate, rapid, cost effective and reproducible UV-Spectrophotometric methods for the simultaneous estimation of Quinfamide and Mebendazole in bulk and in laboratory mixture using 0.01M methanolic HCl as a solvent. The absorption maximum for Quinfamide and Mebendazole were found to be at 260.00 nm and 232.40 nm respectively. Beer’s - lamberts was followed in concentration ranges of 1 - 6 μg/mL for Quinfamide and 2- 12 μg/mL for Mebendazole. The percentage recovery of Quinfamide and mebendazole ranged from 98.48 to 99.08 and 98.83 to 99.62 (Method I); from 98.14 to 98.93 and 99.16 to 99.35 (Method II) for Quinfamide and Mebendazole. The established methods were sensible for simultaneous quantitative determination of both these drugs in fixed dose combinations. Validation of both these methods was performed as per ICH guidelines. The developed methods can routinely be used for estimation of both these drugs in their combined dosage form.

This work has proposed the development and validation of ultraviolet (UV) and visible (Vis) spectrophotometric methods for the determination of norfloxacin in the tablets. The proposed methods were applied to pharmaceutical formulation and percent amount of drug estimated (96.08% for UV method and 102.65% for Vis method) and was found in good agreement with the label claim. Using the UV method norfloxacin showed an absorption maximum at 277 nm, in 0.1 M hydrochloridric acid medium, whereas for the Vis spectrophotometric method it reacts with chloranilic acid reagent, forming a purple solution with an absorption maximum at 520 nm. The calibrations curves were linear over the working range of 2.0-7.0 ?g.mL-1 for the UV method and 90.0-120.0 ?g/mL for the Vis method. The linear regression equation for UV method was y = 0.1303x+0.0026 (r2=0.9999) and for Vis method y = 0.0037x-0.0069 (r2 = 0.9948), they proved to be linear. The methods were completely validated according to the International Conference Harmonization (ICH) guidelines, showing good accuracy, precision, selectivity, linearity and robustness. Therefore the both methods were found to be simple, rapid, sensitive, and easily contributing to the quality control of norfloxacin tablets while being interchangeable. © 2014 JSR Publications.

A simple, rapid, accurate, precise and economic spectrophotometric technique for estimation of tramadol hydrochloride in 0.1N HCl have been developed. Tramadol Hydrochloride exhibit absorbance most 270nm when 0.1N HCl used as solvent proportion, so absorbance was once measured at the identical wavelengths for the determination of Tramadol Hydrochloride obeys Beer Lambert’s law in the concentration range of 20-180µg/ml. The present study describes development and validation of simple and economic UV spectrophotometric method for the estimation of Tramadol Hydrochloride in bulk and injection dosage form using absorbance maxima method. Solubility studies indicated that a Tramadol Hydrochloride shows better solubility in proposed diluents i.e., 0.1N HCl solution the ? max of Tramadol Hydrochloride was found to be 270nm. Because of cost effective and minimal maintenance, the present UV spectrophotometric methods can be preferred at small scale industries as compared to other reported methods.

A new, simple, reliable, fast, sensitive and economical RP-HPLC method was developed and validated for simultaneous estimation of two fixed-dose combinations frequently prescribed in coexisted chronic diseases such as diabetes (GLB) and hypertension (ATN) in bulk for the first time. The mobile phase used for the chromatographic runs consisted of 0.01N potassium dihydrogen ortho phosphate (pH 4.8) and acetonitrile (55:45, v/v). The separation was achieved on column (BDS C18 250 x 2.1mm, 1.6m) using isocratic mode. Drug peaks were well separated and were detected by a UV detector at 235.0 nm. The method was linear at the concentration range 2.5-15µg/ml for Glibenclamide (GLB) and 6.25-37.5µg/ml for Atenolol (ATN), respectively. The method has been validated according to ICH guidelines with respect to system suitability, specificity, precision, accuracy and robustness. The method was validated for system suitability, linearity, accuracy, precision, detection, quantification limits and robustness and was found it is acceptable in the range of 2.5–15 µg/ml for GLB and 6.25–37.5 µg/ml for ATN. The LOD and LOQ of GLB was found to be 0.48 µg/ml and 1.47µg/ml and for ATN was found to be 0.72µg/ml and 2.20 µg/ml, respectively. The method was applied to drug interaction studies of GLB with ATN to illustrate the scope and application of the methods to manage two different therapeutic classes of drugs, as they may co-administered in concurrent diseases.

Objective: The objective of the present work is to develop and validate a new UV derivative spectrophotometric method for simultaneous estimation of metoprolol succinate and ramipril in methanol: water (50:50v/v). Methods: “Zero crossing technique” was chosen for quantitative determination. The zero-crossing points (ZCP’s) were found to be 209 nm where metoprolol succinate was quantified and 211 nm where ramipril was quantified. This method was then subjected to accuracy, linearity, sensitivity and reproducibility according to ICH guidelines to ensure and confirm its validity. Results: The method was found to be obeying Beer’s law in the range of 10-50 µg/ml and 5-25 µg/ml for metoprolol succinate and ramipril, respectively. The % recoveries were observed between the range of 99.2-100.2 for metoprolol succinate and 99.57-99.86 for ramipril. The intra-day and inter-day results showed reproducibility.
