Problems solved by technology

[0006] However, in the research process of Chinese medicine sustained-release preparations, there are the following obstacles: (1) The active ingredients of traditional Chinese medicine are complex, even if the effective parts are extracted and purified, the components are quite complicated, and the mechanical parameters required for the design of traditional Chinese medicine sustained-release preparations cannot be obtained , it is difficult to guide the design of traditional Chinese medicine sustained-release preparations theoretically; (2) most traditional Chinese medicines or effective parts have relatively complex physical and chemical properties, which also increases difficulties in the screening of sustained-release excipients and the design of preparation prescriptions. Difficulties in molding process (Huang Yuan, et al., Research Progress and Existing Problems of Traditional Chinese Medicine Sustained-release Preparations, Chinese Journal of Pharmaceutical Sciences, Vol. 25, No. 4, 2009.)

Abstract

The invention discloses an adrographolidume sustained-release preparation as well as preparation method and use of the same. Categories and dosages of auxiliary materials are screened to prepare the adrographolidume sustained-release preparation; and the preparation can be released at a uniform releasing velocity by about 30%, 60%, 80% and above 90% in 3h, 6h, 10h and 12h respectively, and can becompletely released within predetermined 12 hours. When the adrographolidume sustained-release preparation is adopted, bioavailability of medicine is improved, toxic side effects of adrographolidume on human body is effectively reduced, and the utilization rate of the medicine is ensured as the medicine of the sustained-release preparation is completely released.

Description

technical field [0001] The invention relates to a sustained-release preparation of total andrographis paniculata lactone, a preparation method and application of the preparation, and belongs to the field of medicines. Background technique [0002] Andrographis paniculata (Burm.f.) Nees is the dry aboveground part of Andrographis paniculata (Burm.f.) Nees. Andrographis paniculata has various pharmacological activities such as antibacterial, anti-inflammatory, anticancer, and treatment of cardiovascular diseases. Andrographis paniculata is widely used, has fast absorption in animals, long drug effect, high bioavailability, and has great clinical application value. [0003] The main active ingredients of andrographolide are flavonoids and andrographolide (Andrographolide), neoandrographolide (Neoandrographolide), dehydroandrographolide (dehydroandrographolid), 14-deoxyandrographolide (DA) and 14-deoxy-11,12 -Didehydroandrographolide (DDA), etc., lactones are collectively refer...
