ABSTRACT
Objective:To establish a method to determine the contents of pantoprazole sodium bioadhesive tablets. Methods:An HPLC method was adopted. The determination was performed on a HYPERSIL ODS-2 (150 mm × 4. 6 mm, 5μm) column with mobile phase consisting of 0. 01 mol·L-1 dipotassium phosphate solution –methanol (60 ∶40) at the flow rate of 1. 0 ml·min-1 . The de-tection wavelength was set at 289 nm, the column temperature was maintained at 30 ℃ and the sample size was 20 μl. Results:The linear range of pantoprazole sodium was 1. 28-20. 60μg·ml-1,(r=0. 999 8) . The average recovery was 99. 52%(RSD=1. 43%, n=9). Conclusion:The method is simple, accurate and reliable, and can be used for determining the content of pantoprazole sodium bioadhesive tablets.
