| Zusammenfassung: | The invention provides a puerarin lagging cover slowly-releasing dripping pill which is formed by preparing puerarin quickly-releasing dripping pill core through slowly-releasing lagging cover, wherein the puerarin quickly-releasing dripping pill core is formed by preparing PEG6000 as matrix, and the proportioning by weight of puerarin to PEG6000 is 10:1-3:1. The invention also provides a method for preparing the slowly-releasing dripping pill. In the invention, puerarin is prepared into lagging cover slowly-releasing dripping pill, thereby remarkably increasing the dissolution to solve the problem of difficult dissolution, improving the oral bioavailability and achieves the aim of slow release by controlling the release through the lagging cover. |
