ANTICOAGULANTS ● Heparin ● Clopidogrel ● Warfarin ● Enoxaparin HEPARIN ● Classification: Indirect Thrombin Inhibitor ○ Anticoagulant! ● How it works ○ Thrombin → converts fibrinogen to fibrin → Fibrin forms clots! ○ Antithrombin III inhibits Thrombin ○ Heparin ENHANCES antithrombin III ○ This stops thrombin from being activated, which therefore prevents clots from forming. ● This is the intrinsic coagulation pathway End result? SLOWS DOWN CLOTTING. BASIC INFORMATION ● Uses ○ To prevent blood clots ■ Strokes ■ Chronic a-fib ■ Post-operatively ● Administration ○ Subcutaneous ○ Intravenous ● Titration ○ Patients on a heparin drip have aPTT levels drawn q4-6 hours to titrate the drip.
