1. A drug delivery composition for making individual unit doses in a self-supporting film-dosage form, which individual unit doses cut from a self-supporting continuously cast film contain a desired amount of at least one active, said composition comprising:

  • (i) said self-supporting continuously cast film having said active substantially uniformly stationed therein, said self-supporting continuously cast film formed from a flowable water-soluble or water swellable film-forming matrix comprising a polymer selected from the group consisting of cellulose, a cellulose derivative, polyethylene oxide (PEO), pullulan, hydroxypropylmethyl cellulose (HPMC), hydroxyethyl cellulose (HEC), hydroxypropyl cellulose, polyvinyl pyrrolidone, carboxymethyl cellulose, polyvinyl alcohol, polysaccharides, sodium alginate, xanthan gum, tragancanth gum, guar gum, acacia gum, arabic gum, polyacrylic acid, methylmethacrylate copolymer, carboxyvinyl copolymers, starch, gelatin, and combinations thereof;

    wherein said matrix has a viscosity sufficient to aid in substantially maintaining non-self-aggregating uniformity of said active substantially locked-in the matrix; and

    (ii) a taste-masking agent selected from the group consisting of flavors, sweeteners, flavor enhancers, and combinations thereof to provide taste-masking of said active;

    wherein said active has a particle size of 200 microns or less; and

    wherein the uniformity of the self-supporting continuously cast film is measured by substantially equally sized individual unit doses cut from a self-supporting continuously cast film which do not vary by more than 10% of said desired amount of said at least one active.
