DerBeitrag The present work explores the pharmaceutical application of a novel seeded granulation to develop properties-improved, high drug-loaded, and sustained-release tablets using hydroxypropylcellulose (HPC) as a binder. Itraconazole, 4-acetamidophenol, and rifaximin were selected as model drugs.They differ significantly with respect to particle size distribution and solubility. It can be an alternative to conventional granulation method. High drug loading was possible using the novel seeded granulation method. Drug uniformity was achieved at low liquid/solid ratio. The process could give sustained release formulation. It has good flowability, compactability, and granule strength. As granulated, the correlation among drug properties, binder characteristics, granulation parameters, and product attributes was discussed.粒度为11%HPC-L以4.39ms以上恒定阻塞端速度执行液桥交互作用发生时粗粒子连同微粒粒粒粒粒分队分队进程负责核心壳粒子的形成。

derBeitrag
Metformin hydrochloride is a drug used in the treatment of type 2 diabetes.显示极差流和聚积存储中,直接压缩材料成片片尚未成功实现In a previous study the authors showed that a quasi-emulsion solvent-diffusion (QESD) crystallization technique can be used to drastically improve the flowability and reduce storage agglomeration of this drug.
Highlights
Direct compression of high-dose metformin hydrochloride tablets enabled.
Tablet capping due to porous particle structure avoided through precompression step.
Surfactants used for quasi-emulsion solvent-diffusion can weaken tablets.
This study set out to evaluate whether QESD metformin hydrochloride can be directly compressed into high dose (> 89.5 % drug load) tablets without the use of an intermediary step such as granulation.直接压缩片片片成功,然而重要的是评价素材可按实制作速度按键 。
