a stability indicating high-performance liquid chromatography (hplc) method wasvalidated and used to study the degradation of cetirizine dihydrochloride in acidic and oxidativeconditions. the separation was carried out on a symmetry c18 column and a mixture of 50 mmkh2po4 and acetonitrile (60:40 v/v, ph = 3.5) was used as the mobile phase. the method waslinear over the range of 1-20 μg/ml of ce...
