    Study Notes

    Thrombolytic Agents

    • Used for arterial and venous thrombosis
    • Administered as an intravenous bolus
    • Utilized in acute, massive pulmonary embolism
    • Can cause antigenicity and allergic reactions
    • Protamine and vitamin K are antidotes for heparin and warfarin, respectively

    Thrombolytic Agents: Specifics

    • Alteplase:
      • Considered "fibrin selective" because it rapidly activates plasminogen that is bound to fibrin
      • Has the longest duration of action
    • Anistreplase:
      • Considered "fibrin selective"
    • Streptokinase:
      • Not considered "fibrin selective"
      • One of the oldest thrombolytic agents
    • Tenecteplase:
      • A prodrug
      • Approved for use in ST segment elevation myocardial infarction
    • Urokinase:
      • Not considered "fibrin selective"
      • Has a shorter duration of action
    • Fondaparinux:
      • Not a thrombolytic agent
      • A direct Factor Xa inhibitor
