  • Publication number: 20200215063
    Abstract: Oral film dosage forms that provide improved solubilization and stabilization of an active ingredient in particle form include at least one primary crystallization inhibitor in an amount that inhibits growth and/or agglomeration of the active ingredient, a polyoxyethylated fatty acid glycerides in an amount that further enhances inhibition of crystallization, growth and agglomeration of the particles of the pharmaceutically active ingredient; and at least one plasticizer present in an amount that is effective to increase flexibility and elasticity of the film dosage form.

  • Publication number: 20180078549
    Abstract: Improved pharmaceutical solid oral dosage forms for the buccal and/or sublingual delivery of Tadalafil. The improved delivery systems for solubilizing and stabilizing pharmaceutically active ingredients exhibit enhanced methods of preparation by the use improved solubilization systems which can maintain the Tadalafil in a buccal and/or sublingual oral dosage form or a polymeric film matrix that provides improved bioavailability and/or absorption of Tadalafil.

  • Patent number: 9717682
    Abstract: Improved pharmaceutical solid oral film dosage forms for the buccal and/or sublingual delivery of pharmaceutical, nutraceutical or cosmetic ingredients are endowed with instant hydration potential and complete dissolution potentially enabling the active ingredient to become immediately available for enhanced buccal and/or sublingual absorption and/or reduced absorption through the gastrointestinal route. The improved delivery systems for solubilizing and stabilizing pharmaceutically active ingredients exhibit enhanced stability by the use of a combination of crystallization inhibitors, which together can maintain the active ingredient in a desired plurality of particles in an effective size range within a polymeric film matrix.

  • Patent number: 9301948
    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.
