A dissolvable film for delivering a pharmaceutical agent comprises a first water soluble polymer in an amount of from 2 to 35 weight percent and having a molecular weight from about 5,000 daltons to about 49,000 daltons； a second water soluble polymer in an amount of from 2 to 35 weight percent and having a molecular weight greater than 60,000 daltons； and a pharmaceutically active ingredient. The film has a thickness of about 20 microns to about 1200 microns and is configured to disintegrate after contact with a mucous membrane and thereby release the active ingredient.
