Objective Establish a detection methodology that can quickly, easily, and in large quantities analyze and detect the blood concentration of valproic acid, and can be applied to evaluate the bioequivalence of Sodium Valproate Sustained-Release Tablets in healthy volunteers. Methods Organize subjects to take the test and reference formulations of 0.5 g sodium valproate sustained-release tablets, collect blood samples, and prepare plasma samples. Determine the concentration of valproic acid in plasma using the established ultra performance lc-mass spectrometry/mass spectrometry (UPLC-MS/MS). Results Under fasting and postprandial conditions, both formulations were bioequivalence in terms of absorption rate and degree. Conclusion This experiment established an accurate and rapid UPLC-MS/MS method for detecting the content of valproic acid in human plasma samples. Two formulations have bioequivalence.
