• Hemostatic drugs are:
  • Thrombin: It is obtained from bovine plasma. It is applied as a dry powder or freshly prepared solution on the bleeding surface. It is used in neurosurgery, skin grafting, etc.
  • Fibrin: It is used as sheets or foam for covering or packing bleeding surfaces.
  • Gelatin foam: It is moistened with a thrombin solution and is used for packing wounds.
  • Vasoconstrictors: Like 1% solution of adrenaline may be soaked in sterile cotton gauze and packed to stop epistaxis or other similar bleeding.
  • Astringent: Like tannic acid, it is used for bleeding gums, bleeding piles, etc.
  • Russell’s viper snake venom: This consists of proteolytic enzymes. The venom acts as thromboplastin when it is applied locally and this stops external bleeding in hemophiliacs.
  • Collagen: It leads to the aggregation of platelets and enhances the coagulation cascade.
  • Calcium alginate: This is an absorbable hemostatic and leads to wound healing.
  • Oxidized cellulose: It is also an absorbable hemostatic. Applied over the bleeding site in dry form it swells and causes clotting. This control bleeding from capillaries and arteries.
  • Tranexamic acid: It is applied topically and acts as a hemostatic agent due to its fibrinolytic activity.
