| 摘要: |
| 海藻多糖空心胶囊是以海藻多糖与植物膳食纤维作为主要材料研制的一种植物空心胶囊。对海藻多糖植物空心胶囊(植物壳)、明胶空心胶囊的阿奇霉素、头孢氨苄和布洛芬3种药物模型的胶囊剂进行了药物溶出度和溶出速率的对比研究。结果显示海藻多糖空心胶囊在药物最终溶出量和加速稳定性试验上优于或同等于明胶空心胶囊, 因此海藻多糖空心胶囊具有代替动物明胶空心胶囊的潜在可能性。 |

| Abstract: |
| Algal polysaccharide hard shell capsule is a kind of plant capsule mainly containing algal polysaccharide extracted from marine Rhodophyte and plant cellulose. The performances of in vitro dissolution of cefalexin, azithromycin, and ibuprofen of algal polysaccharide hard shell capsules have been investigated respectively and compared with that of gelatin capsules. This study confirmed that algal polysaccharide hard shell capsules were superior or equal to gelatin capsules in ultimate dissolution rates and accelerated stabilities. In this way, algal polysaccharide hard shell capsules can therefore be considered as a viable alternative to gelatin capsules. |
