  • 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.

  • Patent number: 7132113
    Abstract: An improved rapidly disintegrating flavored film that quickly and completely disintegrates upon contact with mucosal tissue in the oral cavity of a human includes a hydroxypropyl cellulose, a modified starch and a flavor ingredient. The flavored films of this invention completely disintegrate upon contact with the mucosal tissue in less than a minute, and often in less than 30 seconds, whereas previously known flavored films typically do not complete dissolve, or do not dissolve as rapidly, upon contact with mucosal tissue in the oral cavity of a human. The flavored films of this invention may be advantageously employed as breath freshening films, and in food items to impart flavor and, optionally, to impart functional qualities to the food item.
