Studies on Anti-hygroscopic Property of Coated Xianglian Granules / 中药新药与临床药理

Objective To improve the anti-hygroscopic propery of Xianglian granules.Methods Film coating technique was used to screen the film coating dissolvent with the dissolving time and anti-hygroscopic property as the criteria.Results The hygroscopic rate of film-coated granules was lower than that of the uncoated granules,especially the granules coated with polyacrylate resin.Conclusion Xianglian granules coated with polyacrylate resin have good anti-hygroscopic property.
