Determination of Pioglitazone Hydrochloride in Tablets by High-Performance Liquid Chromatography

AMR Lotfy Saber Department of Chemistry, Faculty of Science, Zagazig University, Zagazig, Egypt. -------------------------------------------------------------------------------------------------------------------------------------------Abstract A rapid and accurate HPLC method has been developed for the determination of pioglitazone hydrochloride in tablets. Chromatographic analysis was performed on a Nova-Pak C18 column (3.9mm x 150mm, 5μm) with a mixture of ammonium formate buffer adjusted with formic acid to pH 3 and acetonitrile (75:25, v/v) as mobile phase, at flow rate of 1.0 mL min, and UV detection at 225 nm. The determination was completed in less than 12 min. Linearity ≥ 0.5 μgmL, accuracy ≥ 99.14 %, and precision ≤ 0.6 % were found to be acceptable over the range 0.5 20
