  • Non-gelatin soft capsule system
    Patent number: 8377470
    Abstract: A non-gelatin encapsulation system for liquid filled soft capsules, by nature of the carrier, the cationic-ionic balance of the carrier and the active ingredients, or the concentration of the active ingredients and excipients, are difficult or impossible to commercially encapsulate in gelatin capsules. In particular, the system is adapted for the encapsulation of highly basic, or alkaline, fills. The system provides for a predominantly starch and gelling carrageenan based shell, which displays high resistance to both concentrated fills and to alkaline fills, in particular, to those fills which contain the salt or salts of weak acids and strong bases.
    Type: Grant

  • Soft gelatin capsules containing particulate material
    Patent number: 6217902
    Abstract: Disclosed are suspensions suitable for encapsulation in gelatin capsules, comprising a solid phase consisting of solid particles having a mean diameter of at least about 149 &mgr;m, and a liquid phase capable of suspending the solid phase, the suspension having a predetermined rheology at a temperature suitable for encapsulation into gelatin capsules.
