Abstract
Background: Establishing R, S-enantiomer (S-KT and R-KT) chiral resolution and determination methods for KT are of great significance.
Objective: This study aimed to establish a high-performance liquid chromatography (HPLC) method for the resolution and determination of ketorolac tromethamine (KT) enantiomers.
Methods: A CHIRALPAK AGP column (0.4 × 10 cm, 5 μm) was used with 10 mmol/L ammonium acetate (pH 5.5) and isopropanol (97:3) as the mobile phase. The detection wavelength was 324 nm, the flow rate was 1.0 mL/min, the column temperature was 25°C, and the injection volume was 5 μL.
Results: The resolution between S-KT and R-KT was 2.8. S-KT and R-KT demonstrated a good linear relationship in the range of 3-60 μg/mL (r > 0.999). The average recoveries of S-KT and RKT were 99.2% and 99.8%, with relative standard deviations of 2.0% and 2.4%, respectively.
Conclusion: The established method can be used for the resolution and determination of S-KT and R-KT.
Keywords: Ketorolac tromethamine, enantiomers, HPLC, chiral resolution, determination, respiratory depression.
