| titleOfInvention | A kind of preparation technology of entecavir tablet |
| abstract | The invention provides a preparation process of entecavir tablets. The raw materials are pulverized, then entecavir and a binder are mixed, and oxidized polyethylene wax and p-hydroxyanisole are added for heating and mixing, so as to improve the dispersibility and compatibility of the raw materials , and then reduce the molecular weight of the mixed raw materials by grinding, granulate the mixed raw materials, then add oxidized polyethylene wax again to improve the fluidity of the particles, and finally add fillers to granulate and press to obtain Entecavir tablets; The preparation process is simple in operation, easy to obtain raw materials, easy to realize, and uses few types of auxiliary materials. The prepared entecavir tablets have better content uniformity and compactness, and have good dissolution stability and long-term preservation performance. |
