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.

Abstract
The present invention relates to rapid dissolve thin film drug delivery compositions for the oral administration of active components. The active components are provided as taste-masked or controlled-release coated particles uniformly distributed throughout the film composition. The compositions may be formed by wet casting methods, where the film is cast and controllably dried, or alternatively by an extrusion method.

12. An oral film for mucosal delivery of a desired amount of at least one pharmaceutical and/or bioactive active in substantially equal sized individual unit doses cut from said film, said film comprising:
-
(a) a first film layer comprising; an ingestible, polymer matrix formed from at least one water soluble or water-swellable film-forming polymer; and (b) one or more additional film layer(s) comprising; an ingestible, polymer matrix formed from at least one water-soluble or water-swellable polymer; and wherein at least one of said first film layer and said additional film layer(s) include at least one pharmaceutical and/or bioactive active comprised of particles having a size of 200 microns or less and the matrix of said first film layer or said additional film layer(s) that includes said at least one pharmaceutical and/or bioactive active has a viscosity sufficient to aid in substantially maintaining non-self-aggregating uniformity of said at least one pharmaceutical and/or bioactive active substantially locked-in the matrix, said pharmaceutical and/or bioactive active being substantially uniformly distributed and substantially locked-in said flowable water-soluble or water swellable polymer matrix of said first layer or said additional layer(s); wherein at least one of said first film layer or said additional film layer(s) further comprise a component selected from the group consisting of a taste masking agent, a controlled release agent and combinations thereof; wherein at least one of said first film layer or said additional film layer(s) was continuously cast; and wherein said film is self-supporting and said pharmaceutical and/or bioactive active is substantially uniformly distributed within at least one of said first film layer or said one or more additional film layers, whereby said substantially uniform distribution is such that substantially equal sized individual unit doses cut from said film do not vary by more than 10% from said desired amount of said at least one pharmaceutical and/or bioactive active. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 32)

20. An oral film for mucosal delivery of a desired amount of an active selected from the group consisting of opiates, opiate derivatives, analgesics, biological response modifiers, urinary tract agents, tadalafil, apomorphine, migraine treatments, hormones, alprazolam and combinations thereof, in substantially equal sized individual unit doses cut from said film, said film comprising:
-
(a) a first film layer comprising; (i) an ingestible, polymer matrix formed from at least one water soluble or water-swellable film-forming polymer; and (b) one or more additional film layer(s) comprising; (i) an ingestible, polymer matrix formed from at least one water soluble or water-swellable film-forming polymer; and wherein at least one of said first film layer or said additional film layer(s) include at least one active selected from the group consisting of opiates, opiate derivatives, analgesics, biological response modifiers, urinary tract agents, tadalafil, apomorphine, migraine treatments, hormones, alprazolam and combinations thereof and the matrix of said first film layer or said additional film layer(s) that includes said at least one active has a viscosity sufficient to aid in substantially maintaining non-self-aggregating uniformity of said at least one active substantially locked-in the matrix, said active comprised of particles having a size of 200 microns or less and being substantially uniformly distributed and substantially locked-in said flowable water-soluble or water swellable polymer of said first layer and/or said additional layer(s); wherein at least one of said first film layer or said additional film layer(s) further comprises a component selected from the group consisting of flavors, sweeteners, flavor enhancers, anesthetics, and combinations thereof; wherein at least one of said first film layer and said additional film layer(s) was continuously cast; and wherein said at least one active is substantially uniformly distributed within at least one of said first film layer or said additional film layer(s), whereby said substantially uniform distribution is such that substantially equal sized individual unit doses are cut from said film do not vary by more than 10% from said desired amount of said at least one active; and wherein said individual unit doses are self-supporting. - View Dependent Claims (21, 22, 23, 24, 25, 33)
