Abstract: A coating composition comprising a) a cellulose ether, and b) a water-dispersible starch which has, when measured as a 15 wt.-% dispersion in water at 25° C., a number average particle size of from 0.01 to 2 micrometers and a viscosity of not more than 2000 mPa·s, wherein the weight ratio between the cellulose ether and the water-dispersible starch is from 1:2 to 20:1, is useful for efficiently coating dosage forms with a low moisture permeability.
