【 摘 要 】

Objective: To compare the pharmacokinetic differences of the main components of Naoxintong capsule (NXTC) in normal and acute blood stasis rats. Materials and Methods: Rats were subcutaneously injected with adrenaline hydrochloride twice; during the two subcutaneous injections, the rats were placed in ice water for 4 min to reproduce the model rat of acute blood stasis. The normal and acute blood stasis rats were administrated a 5.04 g/kg dose of NXTC suspension. Then, blood samples were collected from the posterior retinal venous plexus at different time points. Plasma concentrations of four major bio-active components including caffeic acid, ferulic acid, formononetin, and tanshinone IIA in NXTC were measured using ultra-performance liquid chromatography coupled with triple-quadrupole mass spectrometry. Phoenix WinNonlin v6.2 software was used to calculate the pharmacokinetic parameters. Results: Compared with the normal rats, the acute blood stasis rats showed a significant decrease in C max of ferulic acid and formononetin, AUC all of caffeic acid and ferulic acid, and AUC INF_obs of ferulic acid. Conversely, an increase in the Vz_F_obs and MRT last of ferulic acid and caffeic acid was observed. These findings demonstrate that the absorption of the four NXTC components was weakened in the acute blood stasis rats and that the elimination time was prolonged. Conclusions: The significant difference in some parameters of the four NXTC components between the normal and acute blood stasis rats might be caused by an increase in blood viscosity and the subsequent slowing down of blood flow in the acute blood stasis rats. The pharmacokinetic study conducted in pathological state can provide important information and scientific basis for further rational clinical application of NXTC.
