  "country": "US",
  "title": "How to Make Amphetamine Tablets Last Longer in Your Body",
  "original_title": "Extended release amphetamine tablets",
  "summary": "This patent describes a specific type of extended-release amphetamine tablet that combines different forms of amphetamine and special coatings to provide a therapeutic effect for at least thirteen hours after a single dose.",
  "what_it_does": "This patent describes an oral amphetamine tablet designed to release its active ingredient over a long period. The tablet uses a combination of three main components, as detailed in the abstract: an uncoated amphetamine-cation exchange resin complex, a barrier-coated amphetamine-cation exchange resin complex-matrix, and some uncomplexed amphetamine. One or more of these components can include blends of different forms of amphetamines. This specific design ensures that a helpful amount of amphetamine is available in the body within about one hour and continues to work for at least thirteen hours after taking the pill. For example, a person taking this tablet once in the morning would experience the drug's effects throughout the entire day.",
  "what_it_does_not_cover": [
    "Does not cover immediate-release amphetamine tablets that release all their active ingredient quickly.",
    "Does not cover extended-release formulations that achieve their effect solely through a single type of coated amphetamine complex.",
    "Does not cover extended-release mechanisms that do not involve a cation exchange resin complex.",
    "Does not cover formulations that lack either the uncoated complex, the barrier-coated complex-matrix, or the uncomplexed amphetamine component.",
    "Does not cover other types of drugs, only amphetamine compositions."

  "abstract": "An oral amphetamine extended release solid dose is described. The compositions contain a combination of an uncoated amphetamine-cation exchange resin complex, a barrier coated amphetamine—cation exchange resin complex—matrix, and an uncomplexed amphetamine, wherein one or more of these components contains blends of different forms of amphetamines. Either the modified release coated and/or the uncoated amphetamine—cation exchange resin complex may have two forms of amphetamine in a complex with a single cation exchange resin. Following administration of a single dose of the composition, a therapeutically effective amount of amphetamine is reached by about one hour and the composition provides at least a thirteen hour effect post-dose.",
