  • Publication number: 20230404937
    Abstract: Oral film formulations comprising at least one hydrophobic active agent; and a polymeric matrix at least partly composed of hydrophobic or insoluble excipients, or a combination thereof, to facilitate a controlled or sustained dissolution. Wherein when the oral film formulation has an unfavorable environment for fast dissolution, it exhibits partial disintegration within 1 to 10 minutes and a sustained rate of dissolution as confirmed by a disintegration test conducted in a limited volume petri dish, and wherein the film undergoes disintegration into smaller and smaller pieces.

  • 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: 20190247505
    Abstract: Oral thin film dosage form of a stable dispersion of non-solubilized amorphous or partially amorphous active agent(s), having a mean particle size diameter D50 equal or less than 250 ?m, that remains uniformly distributed within a film matrix and contains at least one film forming polymer, and optional pharmaceutically-acceptable excipients, such as diluents, plasticizers, surfactants, sweeteners, and taste-masking agent(s), are prepared by a process including first providing the active agent in an amorphous particle form having a mean particle size diameter D50 equal or less than 250 ?m. Next, the active agent is suspended in a liquid film-forming formulation without dissolving the active agent. Therefore, the solvent is removed to form a film.

  • Publication number: 20160243036
    Abstract: Oral thin film dosage form of a stable dispersion of non-solubilized amorphous or partially amorphous active agent(s), having a mean particle size diameter D50 equal or lower than 250 ?m, that remains uniformly distributed within a film matrix and contains at least one film former polymer, and optional pharmaceutically-acceptable excipients, such as diluents, plasticizers, surfactants, sweeteners, and taste-masking agent(s). The oral thin film dosage exhibits increased solubility or rate of dissolution and enhanced bioavailability compared to a crystalline form of the active agent(s). The oral dosage form also exhibits long term stability confirmed by no changes in the dissolution profile over time.
