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.

A simple, accurate and rapid high performance thin layer chromatography (HPTLC)-densitometry method was developed for separation and determination of chlorthalidone (CHL) and irbesartan (IBS) in pharmaceutical dosage forms. The compounds were separated on silica gel 60 GF254, HPTLC plates using mobile phase of toluene: ethyl acetate: acetonitrile: methanol: ammonia solution (25%) [5:2:2:1:0.2 v/v/v/v] as compact spots at Rf of 0.57 for chlorthalidone and Rf of 0.36 for irbesartan. Densitometric detection was performed at 254 nm. The method was validated in terms of linearity, precision, accuracy, limit of detection (LOD), and limit of quantification (LOQ). The calibration curves were linear in the range of 12.5-75 ng/spot for CHL and 150-900ng/spot for IBS. For CHL recovery varied in range of 99.26-101.25% and for IBS recovery varied in range of 99.76-100.40%. The LOD was found 1.33 and 11.34 ng/spot for CHL and IBS respectively. The LOQ was found 4.03 and 14.37 ng /spot for CHL and IBS respectively. It was observed that the proposed HPTLC method could be used for efficient analysis of the CHL and IBS in combined tablet dosage forms.
