Chloroquine protein binding was determined by equilibrium dialysis of purified plasma proteins and plasma samples from 20 healthy subjects and 14 patients with rheumatoid arthritis. The mean binding was 61 +/- 9% in plasma from healthy subjects (range 46-74%) and 64 +/- 7% in plasma from rheumatoid arthritis patients (range 55-79%). Albumin and alpha 1-acid glycoprotein at physiological concentrations bound chloroquine to an approximately equal extent. Protein binding is unlikely to be an important determinant of chloroquine pharmacokinetics or response.
通过对20名健康受试者和14名类风湿性关节炎患者的纯化血浆蛋白及血浆样本进行平衡透析,测定了氯喹的蛋白结合情况。健康受试者血浆中的平均结合率为61±9%(范围46 - 74%),类风湿性关节炎患者血浆中的平均结合率为64±7%(范围55 - 79%)。生理浓度下的白蛋白和α1 - 酸性糖蛋白对氯喹的结合程度大致相等。蛋白结合不太可能是氯喹药代动力学或反应的重要决定因素。
