  • Patent number: 4800083
    Abstract: A capsule product and method for gradually releasing a medicament for absorption to a body of a warm blooded animal through the gastrointestinal system. The capsule has a fill material which includes a masticatory substance and a medicament that is dispersed throughout the gum. The medicament is of a type that is effectively and desirably released for absorption by the body through the gastrointestinal tract over an extended period of time. The masticatory substance forms a supporting cohesive matrix for the medicament. The gelatin shell, usually formed from gelatin, water, and a plasticizer, formed around the fill material into a capsule of a size and shape to be readily swallowable. Upon swallowing, the gelatin shell is rapidly dissolved in the gastrointestinal juices, while the fill material is substantially insoluble in the gastrointestinal juices.
