Resumen
Descripción general del contenido del recurso.
An isocratic high-performance liquid chromatography (HPLC) procedure was developed for the dissolution rate studies and quantitative determination of valdecoxib in solid dosage forms and in active pharmaceutical ingredient. HPLC separation was carried out by reversed phase chromatography on a Synergi® fusion C18 column (150 mm x 4.6 mm i.d.; 4 µm particle size), held at 30 ºC. The mobile phase consisted of water, pH 7.0/acetonitrile (52:48, v/v), run at a flow rate of 1.0 mL/min and with UV detection at 210 nm. Method validation investigated parameters such as the linearity (r2 =0.9999), range, precision, accuracy, robustness and specificity. The method yielded good results with a quantitation limit of 50 ng/mL and a detection limit of 10 ng/mL. The dissolution test conditions and the dissolution medium was chosen as 0.5% of sodium lauryl sulfate in water at a stirring rate of 75 rpm. The described method can be successfully applied for the analysis of tablets, active pharmaceutical ingredient and drug dissolution studies.
