  • Sachet formulations
    Patent number: 6270804
    Abstract: Bioaffecting sachets, or powders, containing coated liquiflash microspheres and partially recrystallized shearform floss particles are disclosed. The sachets give organoleptically acceptable properties, including a pleasing mouthfeel, when orally ingested.
    Type: Grant
    Filed: October 30, 1998
    Date of Patent: August 7, 2001
    Assignee: Biovail Technologies Ltd.
    Inventors: John J. Getz, Steven E. Frisbee, Tushar K. Misra, John R. Sisak, Pradeepkumar P. Sanghvi
  • Method of preparing a dosage unit by direct tableting and product therefrom
    Patent number: 6083430
    Abstract: The present invention is a process and apparatus for making a dosage unit by direct tableting of shearlite particles. The present invention also includes the dosage unit itself. Shearlite particles, which are prepared by subjecting a feedstock material to liquiflash processing, can be directly fed from a shearlite device to a tableting apparatus without the necessity of any intermediate steps or additional ingredients to facilitate flowability or tablet formation.
    Type: Grant
    Filed: April 29, 1996
    Date of Patent: July 4, 2000
    Assignee: Fuisz Technologies Ltd.
    Inventors: Richard C. Fuisz, Garry L. Myers, Robert K. Yang, Mark R. Herman, Whitney S. Cavanagh, John R. Sisak, Andrea S. Brothers
  • Fast-dissolving comestible units formed under high-speed/high-pressure conditions
    Patent number: 6048541
    Abstract: The invention relates to compositions useful for making tablets which can be formed using conventional tableting machines and which disintegrate rapidly in the mouth with optional chewing. The compositions typically include shearform matrices which have been recrystallized using crystallization promoters.
    Type: Grant
    Filed: August 12, 1998
    Date of Patent: April 11, 2000
    Assignee: Fuisz Technologies Ltd.
    Inventors: Tushar K. Misra, Jeffery W. Currington, Barbara Montwill, Satish V. Kamath, Pradeepkumar P. Sanghvi, John R. Sisak, Michael Raiden
  • Process for forming chewable quickly dispersing comestible unit and product therefrom
    Patent number: 5935600
    Abstract: The present invention deals with compositions and methods for preparing comestible units which disperse quickly in the mouth, especially when chewed. The present invention also includes the product made therefrom. The method includes initiating crystallization of shearform matrix with crystallization/bindig promoter and combining it with an additive to form flowable, compactible micro-particulates. The combination is then shaped to form a comestible unit having high structural integrity, good appearance, and excellent release characteristics.
    Type: Grant
    Filed: June 16, 1998
    Date of Patent: August 10, 1999
    Assignee: Fuisz Technologies Ltd.
    Inventors: Subraman R. Cherukuri, Richard C. Fuisz, Pradeepkumar P. Sanghvi, Tushar K. Misra, John R. Sisak
  • Fast-dissolving comestible units formed under high-speed/high-pressure conditions
    Patent number: 5869098
    Abstract: The invention relates to compositions useful for making tablets which can be formed using conventional tableting machines and which disintegrate rapidly when placed in the mouth. The compositions typically include partially hygroscopic shearform matrices which may be recrystallized using crystallization promoters.
