Abstract

The modified formulation provides a fairly effective way to overcome the problem of bioavailability and results in increasing drug reactions and minimizing fluctuations in blood levels during release. The crosslinker in this study is sodium tripolyphosphate (Na-TPP) which is considered the best binding agent and can produce prolonged drug release. The purpose of this study was to determine the profile of theophylline release from the capsule shell of the alginate-chitosan matrix combination using the crosslink method. The capsule shell was made with the ratio of the percentage of alginate ; chitosan; The TPP are F1 (2%; 2%; 4%) and F2 (4%; 2%; 4%). The difference in percentage is intended to determine the ratio of the most optimal levels of releasing theophylline. The results obtained showed that theophylline capsules from formulas F1 and F2 could release the drug slowly and for a long time to the artificial intestinal fluid pH 7.4 for 8 hours for formula F1 and for 12 hours for formula F2 with a cumulative percentage of release of 99.75%.

修改后的配方提供了一种相当有效的方法来克服生物利用度问题,并导致增加药物反应和最大限度地减少释放期间血液水平的波动。本研究的交联剂是三聚磷酸钠(Na-TPP),它被认为是最好的结合剂,可以产生较长的药物释放。本研究的目的是用交联法测定海藻酸盐-壳聚糖复合基质胶囊壳中茶碱的释放谱。以海藻酸盐的比例制作胶囊壳;壳聚糖;TPP是F1 (2%);2%;4%)和F2 (4%;2%;4%)。百分比的差异是为了确定释放茶碱的最佳水平的比例。结果表明,配方F1和F2的茶碱胶囊在pH 7.4的人工肠液中缓释8小时,F2为12小时,累积释放率为99.75%。
