Title:	Instantly wettable oral film dosage form without surfactant or polyalcohol
Abstract:	An instantly wettable and rapidly disintegrating oral film dosage form without a surfactant and without a polyalcohol was achieved by combining at least one water soluble polymer that is not a copolymer of vinylpyrrolidone, at least one active agent, a copolymer of vinylpyrrolidone and titanium dioxide. In certain embodiments, the film comprises hydroxypropyl cellulose or a combination of hydroxypropyl cellulose and a polymer or copolymer of vinylpyrrolidone or a substituted vinylpyrrolidone as the water soluble polymer(s). A plasticizer, and optional additives selected from synthetic sweeteners, natural sweeteners, flavorants, antioxidants, colorants, and opacifiers, can be added to the disclosed film oral dosage forms.

Application Number:	US14/447,071
Patent Claims:	1. An instantly wettable, rapidly disintegrating film oral dosage form, comprising: at least one water soluble polymer that is not a copolymer of vinylpyrrolidone; at least one copolymer of vinylpyrrolidone in an amount that is effective to increase stiffness of the film as compared to a film without the at least one copolymer of vinylpyrrolidone; titanium dioxide in an amount that is effective to increase a rate of disintegration of the film in an aqueous medium, wherein the ratio by weight of copolymer of vinylpyrrolidone to titanium dioxide in the film is from 3:1 to 5:1; and at least one active agent; wherein the film oral dosage form is substantially free of surfactants and polyalcohols. 2. The oral dosage form of claim 1, further comprising a plasticizer. 3. The oral dosage form of claim 1, further comprising a synthetic sweetener. 4. The oral dosage form of claim 1, further comprising a natural sweetener. 5. The oral dosage form of claim 1, further comprising a flavorant. 6. The oral dosage form of claim 1, further comprising an antioxidant. 7. The oral dosage form of claim 1, in which the at least one water soluble polymer that is not a copolymer of vinylpyrrolidone includes hydroxypropyl cellulose. 8. The oral dosage form of claim 1, in which the at least one water soluble polymer that is not a copolymer of vinylpyrrolidone includes a combination of hydroxypropyl cellulose and polyvinylpyrrolidone. 9. The oral dosage form of claim 1, in which the active agent is selected from the group consisting of rizatriptan, zolmitriptan, alprazolam, diazepam or lorazepam. 10. The oral dosage form of claim 1, in which the active agent is rizatriptan benzoate. 11. The oral dosage form of claim 1, in which the at least one water soluble polymer that is not a copolymer of vinylpyrrolidone consists of a combination of hydroxypropyl cellulose and polyvinylpyrrolidone and further comprising a plasticizer. 12. The oral dosage form of claim 1 further comprising at least one plasticizer and at least one additive selected from the group consisting of synthetic sweeteners, natural sweeteners, flavorants, antioxidants, colorants, and opacifiers. 13. An instantly wettable, rapidly disintegrating film dosage form comprising at least one water soluble polymer that is not a copolymer of vinylpyrrolidone, at least one copolymer of vinylpyrrolidone, at least one active agent, at least one plasticizer, titanium dioxide in an amount that is effective to increase a rate of disintegration of the film in an aqueous medium, wherein the ratio by weight of copolymer of vinylpyrrolidone to titanium dioxide in the film is from 3:1 to 5:1, and optional additives. 14. The oral dosage form of claim 13, in which the plasticizer is triacetin. 15. The oral dosage form of claim 13, in which the at least one water soluble polymer includes hydroxypropyl cellulose. 16. The oral dosage form of claim 13, in which the at least one water soluble polymer consists of a combination of hydroxypropyl cellulose and polyvinylpyrrolidone. 17. The oral dosage form of claim 13, in which the at least one active agent is rizatriptan or rizatriptan benzoate. 18. An instantly wettable, rapidly disintegrating film dosage form consisting of hydroxypropyl cellulose, polyvinylpyrrolidone, triacetin, vinylpyrrolidone-vinyl acetate copolymer, titanium dioxide, and at least one active agent, wherein the ratio of vinylpyrrolidone-vinyl acetate copolymer to titanium dioxide is from 3:1 to 5:1. 19. The oral dosage form of claim 18, in which the at least one active agent is rizatriptan benzoate. 20. An instantly wettable, rapidly disintegrating film oral dosage form, comprising: at least one of a water soluble cellulose derivative and polyvinyl pyrrolidone; at least one copolymer of vinylpyrrolidone in an amount that is effective to increase stiffness of the film as compared to a film without the at least one copolymer of vinylpyrrolidone; titanium dioxide in an amount wherein the ratio of weight of copolymer of vinylpyrrolidone to titanium dioxide in the film is from 3:1 to 5:1; and at least one active agent; wherein the film oral dosage form is substantially free of surfactants and polyalcohols.
