微型胶囊包裹从工艺上开辟了提高药物稳定性、防止药物对胃肠道局部作用、延长药物作用时间等的新方法。微型胶囊可以改善传统药物形式,其中包括片剂。本文介绍氨茶碱微型胶囊包囊的片剂。氨茶碱强烈刺激粘膜,空腹服药很快被吸收,血药浓度达到最高值。微型胶囊包裹可将小量氨茶碱与粘液隔开,因而保证药物通过微型胶囊的半透膜逐步释放。氨茶碱微型胶囊是采用药用乙基纤维素作为保证氨茶碱由胶囊逐步释放的聚合物膜,这种聚合物不溶于胃液和肠液。以丙酮作溶媒,以石腊油作分散介质。通过改变药物和包囊聚合物之比,制成了药核/囊材为6∶1;5∶1;4∶1;2∶1,具有
Micro-capsule package from the process opened up to improve drug stability, to prevent drugs on the gastrointestinal tract, local action, extend the drug action time and other new methods. Microcapsules can improve traditional pharmaceutical forms, including tablets. This article describes aminocyclin microcapsule encapsulated tablets. Aminophylline strongly stimulate the mucosa, fasting medication was quickly absorbed, blood concentration reached its highest value. Microencapsulation can separate a small amount of aminophylline from mucus, thereby ensuring gradual release of the drug through the semipermeable membrane of the microcapsule. Aminophylline microcapsules is the use of medicinal ethyl cellulose as a polymer membrane to ensure the gradual release of aminophylline from the capsule, which is insoluble in gastric and intestinal fluids. Acetone as a solvent to paraffin oil dispersion medium. By changing the ratio of drug to encapsulated polymer, a drug core / capsule material of 6: 1; 5: 1; 4: 1; 2: 1
