  • Chewable drug-delivery composition
    Patent number: 5320848
    Abstract: A non-aqueous, chewable composition for oral delivery of unpalatable drugs is provided. The composition contains the drug intimately dispersed or dissolved in a pharmaceutically-acceptable lipid that is solid at room temperatures. The composition also has a matrix that contains a granulating agent for the total composition and a rapid dispersal agent and optionally additives such as buffering agents, flavoring agents, surfactants, and the like. Methods for the preparation of the chewable compositions are also provided.

  • Low temperature process for preparing neomorphic ibuprofen
    Patent number: 5310960
    Abstract: A novel neomorphic form of ibuprofen and processes for its preparation are provided. The neomorphic ibuprofen is characterized by having a distinctively less bitter and acidic taste commonly associated with conventional ibuprofen and which causes less burning sensation upon swallowing. The neomorphic form of ibuprofen is an amorphous ibuprofen and is prepared by resolidifying supercooled ibuprofen at a process temperature below 0.degree. C.

  • Neomorphic ibuprofen
    Patent number: 5310961
    Abstract: A novel neomorphic form of ibuprofen and processes for preparing the ibuprofen are provided. The neomorphic form is characterized by having a distinctively less bitter taste and causes less burning sensation upon swallowing. The neomorphic form of ibuprofen is an amorphous ibuprofen and is prepared by imparting kinetic energy to supercooled ibuprofen.
