Determination of plasma tranexamic acid using cation-exchange high-performance liquid chromatography with...

A procedure is described for the determination of plasma tranexamic acid concentrations using cation exchange high-performance liquid chromatography with fluorescence detection following post-column derivatisation with omicron-phthalaldehyde. The chromatographic conditions were optimised with respect to detector performance and the method applied to measuring the plasma tranexamic acid levels of patients in a double-blind trial.
