Patent number: 11957785Abstract: An orally administered dosage form that facilitates delivery of an agent locally in the buccal cavity for a sustained period of time includes mucoadhesive particles that are made of at least a mucoadhesive material combined with the agent, and which are dispersed in a disintegrating film. The dosage form is capable of delivering an agent to a patient at the desired oral mucosa site over an extended period of time while reducing patient discomfort or annoyance associated with conventional sustained release mucoadhesive films that must reside on the oral mucosa during the period of sustained release.Type: GrantFiled: June 14, 2021Date of Patent: April 16, 2024Assignee: Intelgenx Corp.Inventors: Rodolphe Obeid, Nadine Paiement, Erick Gonzalez-Labrada

Publication number: 20230404937Abstract: 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.Type: ApplicationFiled: June 9, 2023Publication date: December 21, 2023Applicant: INTELGENX CORP.Inventors: Billal TIR, Carolin MADWAR, Nadine PAIEMENT

Publication number: 20230248660Abstract: 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.Type: ApplicationFiled: March 24, 2023Publication date: August 10, 2023Applicant: Intelgenx Corp.Inventors: Mobarik Bilal, Rodolphe Obeid, Nadine Paiement

Publication number: 20230201130Abstract: 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.Type: ApplicationFiled: February 16, 2023Publication date: June 29, 2023Applicant: 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.
