To establish an HPLC method for the determination of antazoline hydrochloride tablets. NUCLEODUR C18 column was used, the mobile phase was 5 mmol/L sodium acetate (adjusted to pH 3.4 with glacial acetic acid)-triethylamine (100:0.2)-methanol (50:50), the flow rate was 1.0 mL/min, the wavelength of detection was 241 nm, and the column temperature was 35°. The good linearity was obtained over the range of 20.22-202.2 μg/mL. The average recovery rate was 99.83% (RSD = 0.53%; n = 6). The method is accurate and sensitive with better reproducibility. It can be suitable for controlling the quality of antazoline hydrochloride tablets.
