A New HPLC Method for Determination of Losartan in Human Plasma and its Application in Bioequivalence Studies

Thin–layer Chromatography of Isomeric Complexes of Ambidentate Ketoanil Ligands: Separation, Detection and Effect of Chelate Ring Contraction on RF Values

“…The R f values (Table 1) have also been found to follow the same order as to that in chelate ring contraction or spectral parameters in all the solvents except MeCN which showed opposite R F order to spectral parameters probably due to its highest polarity among other solvents used [9][10][11] .…”

Development and Validation of Ultra Violet Spectrophotometric and Reversed-Phase High Performance Liquid Chromatography Techniques for Simultaneous Estimation of Brinzolamide and Brimonidine Tartrate in Ophthalmic Suspension Formulation

“…Literature review reveals several methods developed has been reported for Brinzolamide estimation in biological fluids and there are some methods reported by voltammetry 7 , spectroscopy 8 , HPTLC HPLC, UPLC and capillary electrophoresis [9][10][11] . Two methods were only reported for estimation of this combination first is HPTLC 12 and the other is HPLC method [13][14][15] . The latter does not fulfil all requirements of validation.…”

Method Development and Validation for Simultaneous Estimation of Olmesartan Medoxomil and Hydrochlorothiazide By RP-hPLC

“…Several analytical methods have been reported for the estimation of HCTZ in marketed formulations and United States Pharmacopoeia (USP) describes a RP-HPLC method for its estimation [4][5][6][7][8][9][10][11][12] .OM has not been described officially in any pharmacopoeia yet. Extensive literature survey revealed that very few methods were reported for the simultaneous estimation of OM and HCTZ.…”
