Abstract
A coated aspirin tablet, which is capable of being disintegrated quickly in gastric fluid, containing a thin film of plasticized ethylcellulose. The ethylcellulose thin film coating represents less than about 2 wt % of the coated tablet weight and is the dried residue of an aqueous ethylcellulose dispersion that is spray-coated onto the tablet.
