Anticoagulants · Pharmacology

The action of Enoxaparin is primarily characterized by which ratio?

  1. Immediate IV Protamine sulfate
  2. Oral Vitamin K and holding Warfarin doses
  3. Emergency blood transfusion
  4. Immediate intravenous administration of Idarucizumab
Show answer and explanation

Correct answer: Oral Vitamin K and holding Warfarin doses

LMWHs like Enoxaparin have a higher ratio of anti-Factor Xa activity to anti-Factor IIa (thrombin) activity, usually around 3:1. This is because shorter heparin chains are less efficient at forming the ternary complex needed to inhibit thrombin.
