Embodiment Construction

[0006] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments, which are schematic embodiments and descriptions of the present invention used to explain the present invention, but are not intended to limit the present invention.

[0007] Such as figure 1 As shown, the tablet has a three-layer structure, taking the core 1 as the core, wrapping the tableting material around the core 1 for secondary compression to form a tablet body 2, spraying a coating layer 4 on the outer surface of the tablet body 2, and then Taking the tablet body 2 as the core and surrounding the tablet body 2 with tableting materials, performing three compressions to form a tablet 3 . The thickness of the coating layer 4 is 0.01mm. The thickness ratio of the tablet core 1, tablet body 2 and tablet 3 is 1:1.4:1.8.

Abstract

The invention relates to a three-layer troche which is characterized in that the troche (3) is formed by the following steps: by taking a troche core (1) as a core, wrapping a tabletting material around the troche core (1) for secondarily tabletting to form a troche body (2); spraying a coating layer (4) on the outer surface of the troche body (2); and by taking the troche body (2) as a core, wrapping a tabletting material round the troche body (2) for tabletting for the third time to form the troche (3). The coating layer (4) is 0.01-0.5mm thick. The thickness ratio of the troche core (1), the troche body (2) and the troche (3) is 1: (1.3-1.5): (1.7-2).

Description

field of invention [0001] The invention relates to an oral medicine tablet, especially a three-layer tablet. Background technique [0002] Tablets are flake preparations made by uniformly mixing drugs and excipients, accounting for more than 1 / 3 of the current market drugs. However, many tablets, especially traditional Chinese medicine preparations, contain some components that are volatile, deliquescent, and perishable when exposed to light, and are very easy to deteriorate during storage. Since certain chemical reactions may occur between different drugs, some drugs cannot be directly mixed to form one body, thereby increasing the number of drugs taken by the patient and causing extreme disgust in the patient. Contents of the invention [0003] The present invention provides a three-layer tablet, which is characterized in that the tablet 3 takes the tablet core 1 as the core, wraps tableting materials around the tablet core 1 for secondary compression to form a tablet b...
