  • Publication number: 20200138885
    Abstract: Disclosed is a description and methods for formulating oral films containing lipophilic active ingredient(s), more particularly lipophilic active having a positive logP. The method involves dispersing the lipophilic active(s) in a carrier oil and uniformly distributing them as emulsified oil droplets into a polymer matrix. The methods reported here produce oral films containing a stable emulsion with up to 40% oil phase. The oil phase consists of the carrier oil and lipophilic active(s). This offers the possibility to enhance the amount of lipophilic actives to be included in the film formulation while preserving the film characteristics. The resulting oral films offer a standardized dosage form for lipophilic actives as well as easier and more convenient administration, transportation, handling, and storage.

  • Publication number: 20190314293
    Abstract: A loxapine film oral dosage form includes loxapine salt, free base, or prodrug in an amount effective to provide relief from acute agitation associated with schizophrenia or bipolar 1 disorder via oral transmucosal delivery, dispersed in a polymeric film forming system. Advantageously, the film oral dosage form further includes a sweetener, a refreshing agent, an antioxidant, a pH stabilizer, a penetration enhancer, a mucoadhesive agent and a plasticizer. The loxapine film oral dosage form provides rapid onset of relief from acute agitation associated with schizophrenia or bipolar 1 disorder without presenting pulmonary health risks, thereby reducing risks to patients and others.

  • 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.
