摘要:

采用冷冻聚合法制备了多孔结构的P(NIPAm-co-AAm)智能水凝胶,选用牛血清白蛋白(BSA)为模型药物分子,通过后包裹技术负载蛋白质药物,考察了多孔水凝胶中蛋白质药物的载药量和体外释放行为,研究了不同干燥处理方法对载药后水凝胶的药物控释性能的影响,并且与传统方法制备的P(NIPAmco-AAm)水凝胶进行了药物控释性能对比实验。实验结果表明,在凝胶中引入多孔结构使得P(NIPAm-coAAm)水凝胶的药物载药量和释放量得到了显著的提高。不同的干燥处理方法对多孔P(NIPAm-co-AAm)水凝胶的药物释放影响很大,载药后的凝胶采用冰箱冷冻干燥处理,可使蛋白质药物有较好的缓释效果。

  • Porous poly(N-isopropylamide-co-acrylamide)[P(NIPAm-co-AAm)]hydrogels were prepared by freezing polymerization method.With bovine serum albumin(BSA)as the model drug,it was loaded into porous P(NIPAm-co-AAm)hydrogel by post-fabrication encapsulation technique.The loading efficiency and release ratio of model drug were investigated.The influence of different dry processing method on the controlled drug release properties of the drug-loaded hydrogel was also studied.The results showed that creating an interconnecting pore structure within the hydrogel matrices was an effective strategy to improve the drug loading efficiency and the cumulative released amount.In vitro BSA release from the hydrogels exhibited that dry processing method played a dominant role in the controlled drug release properties of P(NIPAm-co-AAm)hydrogel.The drug-loaded hydrogel with the refrigerator freeze-drying treatment showed better sustained drug release of protein drugs.
