The study was aimed to prepare Bu-Yang-Huan-Wu(BYHW) elementary osmotic pump sustained release tablets and investigate the situation of its main effective components of "synchronous control and sustained release." Release similarity of chromatographic finger prints of BYHW in vitro dissolution was evaluated.The results showed that BYHW elementary osmotic pump sustained-release tablet was prepared and the chromatographic finger prints were extracted.And data of its release similarity was also obtained.It was concluded that BYHW elementary osmotic pump sustained-release tablet can achieve the synchronous control and sustained release of many ingredient.It is also fit for the characteristic of Chinese herbal medicine compound.
