  • Patent number: 9820937
    Abstract: The invention described herein provides a fast dispersing oral solid dosage form containing monoamine oxidase B inhibitor (MAO-B inhibitor) as the active ingredient, and method of treating disease therewith, such as Parkinson's disease. In one embodiment, the monoamine oxidase B inhibitor selegiline or its analog can be the sole active ingredient in the composition administered. The dosage form composition is formulated to promote absorption through the buccal, sublingual, pharyngeal and/or esophageal mucous membrane tissue, such that at least 5% of the active ingredient is absorbed within one minute of placement in the oral cavity, as determined by a buccal absorption test. Monoamine oxidase B inhibitor compounds administered in accordance with the invention decrease the amount of undesirable metabolites associated with first pass effect of selegiline, for example, such as amphetamine and methamphetamine.

  • Patent number: 7090866
    Abstract: This invention relates to a pharmaceutical composition for oral administration comprising a carrier and, as active ingredient, an opioid (? receptor) agonist, such as fentanyl, or a salt thereof, characterized in that the composition is in the form of a fast-dispersing dosage form designed to release the active ingredient rapidly in the oral cavity. A process for preparing such a composition and the use of such a composition as an analgesic, for the treatment of chronic pain and/or breakthrough pain, as an anesthetic premedication, for the induction of anesthesia, as a sedative and/or for the treatment of anxiety are also provided.

  • Patent number: 6316027
    Abstract: In one embodiment, this invention relates to a pharmaceutical composition for oral administration consisting essentially of a gelatin at a concentration up to 5% by weight as a carrier, a solvent, and, as an active ingredient, a dopamine agonist. Alternatively, the invention relates to a composition that takes the form of a solid, unitary fast-dispersing dosage form comprised of a network of an active ingredient after and a water-soluble or water dispersible matrix forming agent or carrier which is inert towards the active ingredient after subliming solvent from the composition in the solid state. The dosage is designed to completely disintegrate within 1 to 30 seconds of being placed in the oral cavity. Compositions which further comprise an anti-emetic and/or an opioid antagonist are also provided herein.
