Patent number: 11602504Abstract: 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.Type: GrantFiled: April 15, 2019Date of Patent: March 14, 2023Assignee: INTELGENX CORP.Inventors: Carolin Madwar, Nadine Paiement, Rodolphe Obeid, Justin Conway, Erick Gonzalez-Labrada

Publication number: 20220395452Abstract: Disclosed is a method of administration and device for the improved bioavailability of leukotriene receptor antagonists. This method and device involve an alkaline surface pH oral film dosage form designed to deliver leukotriene receptor antagonists, such as Montelukast, to the stomach in an amorphous precipitate suspended in aqueous medium. Also disclosed is a device and method for treating a disease, such as a neurodegenerative disease or condition associated with neuroinflammation induced by a leukotriene. The device is a film unit dosage form having an alkaline surface pH film layer and a safe and effective amount of Montelukast. The device is configured and formulated to predominantly achieve enteral delivery of the Montelukast. The method includes enterally delivering to a human or an animal in need of treatment, a safe and effective amount of Montelukast capable of crossing the blood-brain barrier.Type: ApplicationFiled: April 28, 2022Publication date: December 15, 2022Applicant: INTELGENX CORP.Inventors: Nadine PAIEMENT, Horst G.
