Problems solved by technology

However, the preparation of sustained-release pellets is relatively difficult. The main difficulty is that the surface of the pellets is a more regular spherical shape, and the friction with the tableting auxiliary materials is small. In the process of mixing with the tableting auxiliary materials, it is easy Stratification occurs, which greatly affects the content uniformity of compressed tablets

Abstract

The invention relates to huperzine A sustained-release pellets coated granules, sustained-release pellets and a preparation method thereof. The huperzine A sustained-release pellets coated granules ofthe present invention are prepared from the following raw materials in parts by weight: 100 parts of huperzine A sustained-release pellets, 5-15 parts of a binder A, and 55-75 parts of coating auxiliary materials. The binder A is hydroxypropyl cellulose; the coating auxiliary materials are composed of the following components in parts by weight: 20-30 parts of microcrystalline cellulose, 10-20 parts of corn starch, 10-20 parts of lactose, and 10 parts of carboxyl methyl starch sodium. The huperzine A sustained-release pellets coated granules of the invention have the high-roughness pellet surface, and have a slow and stable release effect. The huperzine A sustained-release pellets prepared by further preparation of the huperzine A sustained-release pellets coated granules have good drug content uniformity and have the sustained release effect similar to that of the sustained-release pellets coated granules.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical preparations, in particular to a Huperzine A sustained-release pellet-coated granule, a sustained-release pellet tablet and a preparation method thereof. Background technique [0002] Huperzine A is a drug for the treatment of middle-aged and elderly benign memory disorders and various types of dementia, memory cognitive function and emotional behavior disorders. The drug has high biological activity, has high lipid solubility, easily penetrates the blood-brain barrier, and is distributed in the brain areas closely related to learning and memory after entering the central nervous system. At low doses, acetylcholinesterase ( AchE) has a strong inhibitory effect, which significantly increases the content of acetylcholine (Ach) in the synaptic space in the distribution area, thereby enhancing neuronal excitation conduction, strengthening the excitation effect of learning and memory brain areas...
