OBJECTIVE To establish a method for the dissolution determination of paracetamol,pseudoephedrine hydrochloride and chlorphenamine maleate dispersible tablets. METHODS HPLC was performed on the column of Agilent HC-C_(18)( 4.6 mm×250 mm,5 μm). The mobile phase for paracetamol was methanol-0. 05 mol·L~(-1) Potassium dihydrogen phosphate-triethylamine( 20 ∶ 80 ∶0.02,V/V),and the wavelength was 244 nm. The mobile phase for pseudoephedrine hydrochloride and chlorphenamine maleate was 0.5% acetonitrile-dodecyl su...
