Patent ID: 8778399

Claim:
A process of making a dosage form product that comprises a core and a film-coating, the process comprising the steps of preparing a core from a pharmaceutically active ingredient and a material comprising a water-soluble, film-forming polymer with a weight average molecular weight of at least 12,000, wherein the film-forming polymer is a cellulose ester or a cellulose ether, compressing the core into a desired size and shape, and then coating the core by activating the film-forming polymer in the core by contacting the core with a sufficient amount of liquid activating fluid containing a surface tension lowering agent and at least 90 percent by weight water to hydrate the film-forming polymer into a film coating on the core, wherein no film-forming polymer is contained in the activating fluid, and wherein the core and film coating each have a chemical composition that is essentially the same as the other.
