  • Publication number: 20020022057
    Abstract: An alternate drug delivery system for dissolution of pharmaceuticals in the mouth wherein a therapeutically effective amount of a drug is encapsulated using an encapsulation method. Encapsulation reduces the perceived off flavors of drugs, allowing the active components to dissolve pleasantly in the mouth. This allows more rapid absorption of the active compounds through the oral cavity compared to traditional tablets, which require breakdown and absorption in the gastrointestinal tract. The delivery system can be incorporated into a variety of applications, such as breath mint tablets or chewing gum. Benefits of this invention include portability and the ability to take pharmaceuticals without water and without the off taste of chewable tablets, thereby leading to increased patient compliance.

    Abstract: A purine compound, which has a desired and an undesired effect when a dosage sufficient to induce the desired effect is administered to a mammal, is combined with a counteracting agent, wherein the counteracting agent can reduce the undesired effect when the combination containing an effective amount of the purine compound is administered to a mammal. In a preferred embodiment, an adenosine compound is combined in vitro with a catecholamine in a predetermined ratio to form an adenosine composition. Very high dosages of a purine compound, such as adenosine, ATP or their analogs can be administered to a mammal via administration of compositions containing the purine compound and a counteracting agent, while reducing the dangerous, undesired effects associated with administering the same dosage of purine compound without first combining it with the counteracting agent.

  • Patent number: 5679650
    Abstract: A purine compound, which has a desired and an undesired effect when a dosage sufficient to induce the desired effect is administered to a mammal, is combined with a counteracting agent, wherein the counteracting agent can reduce the undesired effect when the combination containing an effective amount of the purine compound is administered to a mammal. In a preferred embodiment, an adenosine compound is combined in vitro with a catecholamine in a predetermined ratio to form an adenosine composition. Very high dosages of a purine compound, such as adenosine, ATP or their analogs can be administered to a mammal via administration of compositions containing the purine compound and a counteracting agent, while reducing the dangerous, undesired effects associated with administering the same dosage of purine compound without first combining it with the counteracting agent. New catecholamine compositions are also taught.
