The aim of this study was to investigate the synergistic effect and underlying mechanism of compatibility of Aconiti Lateralis Radix Praeparata water-soluble alkaloids (FWA) and Ginseng Radix et Rhizoma total ginsenosides (RTG) on propafenone hydrochloride induced acute heart failure (AHF) rats. Firstly, hemodynamics and serum biochemical indexes were measured to observe the therapeutic effect of FWA, RTG and their compatibility on AHF rats. Non-target serum metabolomics and multicomponent pharmacokinetic experiments were then performed to reveal the mechanism from the two aspects of body reaction and drug behavior in vivo. Data showed the haemodynamics indexes (maximum change rate of left ventricular pressure, heart rate) and neuroendocrine cytokines (TNF-α and Nt-proBNP) levels in rats treated by compatibility of FWA and RTG were improved more significantly than that treated by single drug. Through metabolomics analysis, six metabolites, including L-pipecolic acid, L-arginine, uric acid, N-benzoylglycine, sphingosine-1-phosphate and phosphatidylinositol lyso 16:0, were selected and identified as the potential biomarkers of the synergistic effect. Furthermore, lysine degradation, arginine and proline metabolism, purine metabolism, sphingolipid metabolism, etc. were the differential pathways involved. The results of pharmacokinetics showed C_max, AUC_last and t_1/2 of the four components (uracil, salsolinol, guanosine, higenamine) of FWA in compatibility group were obviously higher than that in single drug group, which indicated the absorption and bioavailability of these alkaloids were increased, and the residence time was prolonged after FWA combined with RTG. In conclusion, the therapeutic effect of FWA-RTG on AHF rats was enhanced and that might because the compatibility of FWA-RTG affected the process of some metabolites in AHF rats, and pharmacokinetic behavior of components in FWA was obviously influenced after co-administered with RTG.
