摘要： Disclosed is a description and methods for formulating oral films containing lipophilic active ingredient(s), more particularly lipophilic active having a positive log P. 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.
