摘要 基于荧光光谱分析技术,通过体外模拟生理环境实验和动物体内实验探索了地西泮与乙醇的协同作用机制.研究结果表明,在地西泮体内代谢初期,血液中乙醇的存在可以降低地西泮-人血清白蛋白(HSA)络合物的结合平衡常数,致使血液中地西泮游离分子的浓度相对增大,可加速地西泮分子的代谢速率,降低药物的半衰期,从而增强地西泮在体内的药效,产生协同作用. The synergistic mechanism of diazepam and ethanol was investigated based on fluorescence spectroscopic method by simulating the physiological environment in vitro and the in vivo experiments in mice.The experimental results revealed that the presence of ethanol in the blood can reduce the equilibrium binding constant of diazepam-HSA complex in the early metabolism of diazepam,which resulted in the increase of the free diazepam proportion,accelerating the metabolic rate of diazepam,and shorten the half-life and storage time of diazepam in the blood,thereby enhancing its bioactive efficacy.
