A high performance liquid chromatographic method with UV detection was developed and validated for simultaneous determination of Pioglitazone and Clopidogrel. Separation was performed on a C18 column by isocratic elution with a mobile phase of Methanol: Acetonitrile: Water (80:10:10) at pH 4.6. The UV detection was set at 230 nm. The method proved to be specific, accurate, precise and linear over the concentration ranges of 20-120ppm for both Pioglitazone and Clopidogrel with correlation coefficients always >0.999 for both drugs. The intra-day and inter-day precision and accuracy were less than 2 for both analytes.

Amiloride Hydrochloride

Abstract A high-performance liquid chromatographic method was developed for the simultaneous determination of 2 ternary mixtures containing amiloride hydrochloride, atenolol, hydrochlorothiazide, and chlorthalidone used in hypertension therapy. The use of cyanopropyl column results in satisfactory separation of both mixtures. The mobile phase consisted of 10 mM KH2PO4 buffer (pH 4.5) and methanol in a ratio of (75 25 v/v), at a flow rate of 1 mL/min. UV detector was operated at 275 nm. Calibration graphs were linear in the concentration ranges of 210, 20200, 10100, and 550 g/mL for amiloride hydrochloride, atenolol, hydrochlorothiazide, and chlorthalidone, respectively. Intraday and interday precision values (relative standard deviation) were <1.13 for mixture I (amiloride hydrochloride, atenolol, chlorthalidone), and <0.93 for mixture II (amiloride hydrochloride, atenolol, hydrochlorothiazide). The method was successfully applied for the determination of the 2 combinations in laboratory-prepared mixtures and commercial pharmaceutical formulation with high accuracy and precision. Statistical comparison of the results with those of the published methods showed excellent agreement and indicates no significant difference between them.
