Abstract: | OBJECTIVE To establish an optimized HPLC method for determination of related substances in Montelukast Sodium Chewable Tablets. METHODS The chromatography analysis was performed on a phenyl col- umn (4.6mm× 50mm, 1.8 μm) using gradient elution of a mobile phase consisted of solvents A and B. The A solvent was 20mmol. L-1 disodium hydrogen phosphate (pH 5.7 adjusted by phosphoric acid) ;the B solvent was acetoni- trile. The flow rate was 1.2mL . min-1 and the detection wavelength was 238nm. The column temperature was set at 30℃. RESULTS This method had been validated under various conditions, and montelukast related substances were completely separated from each other. CONCLUSION The method can be used for quality control of Monte- lukst Sodium Chewable Tablets. |
