  • Publication number: 20220395452
    Abstract: 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.

  • Patent number: 10722476
    Abstract: Disclosed is a device and method for treating a neurodegenerative disease or condition associated with neuroinflammation induced by a leukotriene. The device is a film unit dosage form having a film layer and a safe and effective amount of a leukotriene receptor antagonist or leukotriene synthesis inhibitor. The device is configured and formulated to achieve transmucosal and/or enteral delivery of the leukotriene receptor antagonist or leukotriene synthesis inhibitor. The method includes transmucosally and/or enterally delivering to an animal in need of treatment, a safe and effective amount of a leukotriene blocker capable of crossing the blood-brain barrier.

  • Patent number: 8735374
    Abstract: A direct compression formulation suitable for preparing buccal and/or sublingual and dosage forms incorporates a combination of a non-ionic polymeric solubility enhancer, a mucoadhesive polymer, a filler, a disintegrant, and a pharmaceutically active agent. Cannabinoid-cyclodextrin complexes exhibiting an improved property selected from improved stability, higher product yield and improved product uniformity may be obtained by complexing the cannabinoid with the cyclodextrin in a liquid medium containing an antioxidant. To enhance stability, product yield and/or product uniformity, complexing may be done while the liquid medium is in contact with an atmosphere having a very low oxygen content.
