  • Publication number: 20150057228
    Abstract: The present invention relates antidotes to anticoagulants targeting factor Xa. The antidoes are factor Xa protein derivatives that bind to the factor Xa inhibitors thereby substantially neutralizing them but do not assemble into the prothrombinase complex. The derivatives describe herein lack or have reduced intrinsic coagulant activity. Disclosed herein are methods of stopping or preventing bleeding in a patient that is currently undergoing anticoagulant therapy with a factor Xa inhibitor.

  • Publication number: 20090202673
    Abstract: A chewing gum composition contains a gum base; 0% to about 60%, preferably about 10% to about 50%, bulking and sweetening agents; and about 5% to about 80% fat-containing confection, such as chocolate.

The gum base usually contains less than 10% filler, and less than 45% gum base matrix disrupting materials. In another embodiment, the chewing gum product is made from gum base and flavoring agents, possibly without the addition of any bulk sweetening agents. A chewing gum product can be formed from the composition. The product may be a compressed gum product. In another embodiment, the product can be coated or filled with a fat-containing confection, such as chocolate, in which case the product may be made of a composition without the fat-containing confection in it and with 0% to about 60% bulking and sweetening agent.
