Salbutamol sulfate and ketotifen fumarate are used in combination for the treatment of asthma. The present work deals with method development for simultaneous estimation of salbutamol sulfate and ketotifen fumarate in two-component tablet formulation by first-order derivative spectroscopy. For determination of sampling wavelength, 10 μg/mL of each of salbutamol and ketotifen was scanned in 200–400 nm ranges and sampling wavelengths were found to be 257 nm for salbutamol and 278 nm for ketotifen in first-order derivative spectroscopy. In this method, linearity was observed in the ranges of 5–45 μg/mL for salbutamol and 5–35 μg/mL for ketotifen. The % recovery was within the range between 98 and 102%, and % relative standard deviation for precision and accuracy of the method was found to be less than 2%. The method is validated as per international conference on harmonization guidelines. The method can be successfully applied for the simultaneous analysis of both drugs in pharmaceutical dosage forms.

Aim of present work was to develop and validate a simple, precise and accurate uv-vis spectrophotometric method for the simultaneous estimation of gemifloxacin mesylate (GEMI) and ambroxol HCl (AMB) in their combined tablet dosage form. The method is based on first-order derivative spectroscopy. For determination of sampling wavelengths, each of GEMI and AMB were scanned in the wavelength range of 200–400 nm in the spectrum mode and sampling wavelengths were selected at 360 nm (zero crossing of GEMI) where AMB showed considerable absorbance and at 221.6 nm (zero crossing of AMB) where GEMI showed considerable absorbance. The linearity was obtained in the concentration range of 32-192 µg/ml for GEMI and 7.5-45 µg/ml for AMB. The correlation coefficients were found to be 0.9987 and 0.9992 for GEMI and AMB, respectively. The method was validated as per ICH guidelines. Mean recoveries were found satisfactory. All the data of validation study was found to be satisfactorily. The proposed method can be applied for simultaneous estimation of both the drugs

A simple, rapid reverse phase high-performance liquid chromatographic method was developed and validated for the simultaneous estimation of Ezetimibe and Simvastatin in bulk and pharmaceutical dosage forms. Chromatography was carried out by using Chromosil C-18,column having 250 x 4.6mm internal diameter with a mixture of Methanol:Acetonitrile:0.1%Orthophosphoric Aid in the ratio of 75:20:05 (v/v/v) as mobile phase. Determination of the different analytical parameters such as linearity, precision, accuracy, and specificity, limit of detection (LOD) and limit of quantification (LOQ) was done. The calibration curve was found to be linear for each analyte in the desired concentration range. The average recovery was found to be 99.88 and 100.12 for Ezetimibe and Simvastatin respectively. The proposed method is highly sensitive, precise and accurate, which was evident from the LOD value of 1.2ppm and 0.25ppm for Ezetimibe and Simvastatin respectively and hence the present method can be applied successfully for the quantification of active pharmaceutical ingredient (API) content in the combined formulations of Ezetimibe and Simvastatin.
