  • Warfarin® Form of Warfarin®
  • heparin has a significantly shorter half-life, which makes it easier to control the anticoagulant if bleeding complications occur, without having to forego the necessary protection against thrombosis.
  • postoperative bleeding is also caused by the piasmin system.
  • the piasmin system the physiological antagonist of the blood coagulation system, ensures a dissolution of at a systemic level Blood clots. However, this function is not desirable if there is an increased risk of bleeding after surgery.
  • the optimal local wound care is the same for both concepts: after the extraction of the teeth or after a smaller dental intervention, the bone wound is tamponized with a collagen vial (e.g. Lyostypt) or a gelatin sponge (e.g. Topostatin).
  • a collagen vial e.g. Lyostypt

  • a wound protection plate made of plastic is often used in patients and attached to the remaining teeth.
  • the object of the present invention is therefore to provide a pharmaceutical formulation with which the active end product of the blood coagulation cascade, thrombin, can be made available over a limited period of time.
  • the period until stable intraoral wound healing is considered to be the required period of time. This corresponds to 7 to 10 days. After this period, stable wound healing has occurred, which means that external mechanical influences on the wound can no longer have any effect.
