LOW TEMPERATURE COATINGS

摘要

A method of coating an active material is provided. The method comprises contacting an active material with a film-forming composition comprising an aqueous dispersion of an amylose-alcohol complex, an insoluble film-forming polymer and a plasticiser at a temperature of less than 60 DEG C. The method finds particular application in the preparation of dosage forms comprising active materials that are unstable at temperatures in excess of 60 DEG C. The compositions prepared in accordance with the method can be used to deliver an active material to the colon.
