Since VPA has an unusual nonlinear binding characteristic and a wide interindividual variation, monitoring of its free concentration can be helpful in patient management. The determination of unbound VPA is more difficult(More)
The derivatization of valproic acid and undecylenic acid with 4-bromomethyl-7-methoxycoumarin is described. The derivatives were detected by photodiode-array and fluorescence detectors. The optimum monitoring conditions and the stability of the suspension solution and derivatives were investigated. A high-performance liquid chromatographic (HPLC) method(More)
