Abstract

The invention relates to a film coating agent for an extract medicament solid preparation, which comprises the following components in parts by weight: 30-60 parts of hydroxypropyl methyl cellulose, 5-30 parts of plasticizer and 2-30 parts of stearic acid. The invention also relates to a preparation method of the film coating agent, which comprises the following steps of: (1) weighing the hydroxypropyl methyl cellulose, the plasticizer and the stearic acid in parts by weight; and (2) adding the hydroxypropyl methyl cellulose, the plasticizer and the stearic acid into a high-speed shearing machine and uniformly mixing the materials at the speed of 350-600 rpm to prepare a coating agent finished product. The coating agent is safe and non-toxic, and can form a hydrophobic molecular layer onthe surface of a medicament for inhibiting the adsorption and osmosis of steam on the surface of a coating film, thereby reducing the moisture absorbing rate of a medicament coating tablet and preventing the damping and hardening of the medicament and medicament efficiency loss; meanwhile, the coating film has strong flexibility, and the coating quality is stable; and the preparation method has the outstanding advantages of high production efficiency, low energy consumption, favorable application performance of coating agent finished products, and the like.

Description

technical field [0001] The invention belongs to the field of coating agents, in particular to a film coating agent for solid preparations of medicinal extracts and a preparation method thereof. Background technique [0002] Many products in traditional Chinese medicine tablets are extract tablets, which contain many ingredients that are easy to absorb moisture. They are easy to soften and absorb moisture under the influence of heat and humidity, resulting in deformation of the tablet core, hardening of the drug, and inability to completely disintegrate, affecting the efficacy of the drug; moreover, moisture absorption can also Cause agglomeration, fluidity reduction, deliquescence, crystal form change, etc. of the preparation, and then cause color change, content reduction or compatibility change between components; after moisture absorption, the preparation is more likely to be oxidized, hydrolyzed, and mildewed, making the physical stability of the preparation , chemical s...
