The S-SMEDDS with dextran 40 as solid carrier, consisted of well-separated spherical particles and could form microemulsion with droplet size less than 50nm followed by dilution in water. Nimodipine in the S-SMEDDS was in the amorphous or molecular dispersion state. The S-SMEDDS had a faster in vitro release rate than the conventional tablet.
其中以右旋糖酐40为载体的S-SMEDDS,由分离良好的球形颗粒组成,药物以无定形或分子分散状态存在,水重分散后形成粒径小于50nm的微乳,体外溶出快速,显著高于市售片剂。

In this report, half-esterification between these pendent hydroxyl groups of hydroxyl-PU and maleic anhydride could lead to new pendent groups, carboxylic groups. These highly polar carboxylic groups in the side chain of PU could play the role of internal emulsifier. They had self-dissociation ability in the water or were neutralized first by appropriate amount of base. Then, PU bearing carboxylic group could dispersed steadily in the water, named aqueous-based polyurethane dispersion.
在本论文中,利用原来亲油性Hydroxyl PU主链段上悬挂的羟基经由与琥珀酸酐的半酯化(Half-esterification Reaction)反应后,使PU在侧链上悬挂具有强极性的羧酸基,其可作为聚胺酯分子中的内乳化剂,羧酸基能在水相中自身解离产生离子或加入适量碱使之中合,使聚氨酯高分子能够稳定分散於水中,即所谓水性PU分散液(Aqueous-based Polyurethane Dispersion)。
