A simple, sensitive and rapid reverse phase high performance liquid chromatographic method was developed for the estimation of Metformin Hcl (MET) and Pioglitazone (PIO) in pure and in pharmaceutical dosage forms. A Gemini C18 column (150x4.6mm, 5μ) was used with a mobile phase containing a mixture of Acetonitrile and Ammonium Acetate buffer (pH-3) in the ratio of 42: 58. The flow rate was 0.3m...

A stability-indicating HPLC assay method has been developed and validated for valsartan in bulk drug and pharmaceutical dosage forms. An isocratic RP-HPLC was achieved on Waters 2695 using Symmetry C18 (250mm × 4.6mm × 5μ) column with the mobile phase consisting of 0.02 mM sodium dihydrogen ortho-phosphate, pH adjusted to 2.5 using ortho-phosphoric acid (solvent A), and acetonitrile (solvent B)...

In this study we have reported a new, fast and extraction free spectrophotometric procedure for the assessment of caroverine in pharmaceutical raw and tablet dosage forms. In the reported visible spectrophotometric procedure tungstate in Folin-Ciocalteu phenol reagent is reduced in alkaline medium and produces the blue colored chromogen that shows Λmax at 740nm with the calibration range of 2-2...

The present study was designed to develop a simple, validated liquid chromatographic method for the analysis of azithromycin in bulk and pharmaceutical dosage forms using ultraviolet detector. The best stationary phase was determined as C18 column, 5 μm, 250 mm × 4.6 mm. Mobile phase was optimized to obtain a fast and selective separation of the drug. Flow rate was 1.5 mL/min, Wavelength was se...
