Abstract

The invention relates to a gastric-juice-soluble film-coating premix and the preparation method. The components include film-forming material (principal film-forming material and non-principal film-forming material), plasticizer, antisticking agent, surfactant and unorganic colorant. The preparation method of the gastric-juice-soluble film-coat premix is that: principle film-forming material is put into a super-mixer whose temperature is between 20 to 80 DEG C to mix at a low speed for 5minutes,and then after the plasticizer and the surfactant being added, to mix at a high speed for 20 minutes to get dispersive medium; then the dispersive medium, the lubricant and the unorganic colorant are added into the super-mixer to be dispersed at a high speed for 30 minutes; then the non-principal film-forming material and the plasticizer are added to mix at a low speed for 5 minutes; the finished product can be got after being screened. The gastric-juice-soluble film-coat premix which adopts complete hydrosolvent system is of moderate viscosity, so that good suspending state can be maintained; relatively low permeability can ensure the stability of the preparation; with improved production efficiency, improved moistureproof effect of the traditional Chinese medicine, more delicate coat and brighter color, the invention can better meet the requirements of the solid medicine for the film-coating.

Description

technical field [0001] The invention relates to a film coating premix and a preparation method of the film coating premix. technical background [0002] Film coating is to uniformly spray a layer of relatively stable polymer material on the surface of solid pharmaceutical preparations by spraying to form a plastic film layer with a thickness of several microns. [1-2] . Film coating agents are usually made of film-forming materials, plasticizers, anti-sticking agents, surfactants and inorganic colorants through a simple physical mixing manufacturing process [2] In this way, the film-coated tablet not only has the functions of moisture-proof, light-proof, taste-masking, wear-resistant, mildew-resistant, and easy to disintegrate, but also greatly improves the dissolution rate, bioavailability and validity period of the drug, expanding the The countries and regions where the drug can be sold have strongly promoted the export of drugs [3-5] The weight gain of the coating is on...
