生物活性:聚山梨酯 20 是一种聚氧乙烯 (POE) 型非离子表面活性剂[1][2][3]。
体外:添加聚山梨醇酯20可以改变木质素的表面性质,改变其疏水性、氢键结合能力和表面电荷,从而减少蛋白质的非生产性吸附[1]。
聚山梨酯20(0.35%-0.7% w/w)加入到0.05 mol/L pH 6.5的磷酸盐缓冲液中,可显着提高药物的表观溶解度,从0.8 μg/ml甚至增加到353 μg/ml,同时其作用在较低 pH 值或水中的含量要小得多(在 pH 值 4.5 时为 20 μg/ml)。在 pH 6.5 和 0.7% 聚山梨醇酯 20 存在下,磷酸盐浓度 (0.2 mol/l) 的增加导致坎地沙坦酯溶解度进一步增加至 620 μg/ml[2]。
