Abstract A macromolecular coating for solid medicament contains the components of (wt%) 40-55% of cellulose ether, 25-35 % of inorganic filler and pigment, 0-5% of other additive, 20-30% of plasticizer and 0.2-1% of emulsifier, in which the cellulose ether is water-soluble cellulose ether whose viscosity is 20-75 centipoises, and the emulsifier is an edible oil-in-water emulsifier. Its preparation method is characterized by that all the ingredients are placed in high-speed mixing machine, stirred and uniformly mixed, then stored for 10-20 days in a closed container. It is simple in production process, low in cost and is favorable for medicine production.
