Vorapaxar Blood Clotting Uses Side Effects Dosage

vorapaxar

Vorapaxar is used to reduce the risk of blood clot formation in adult patients with a history of heart attack or peripheral artery disease. It reduces the rate of cardiovascular death, heart attack, stroke, and the need for emergency coronary artery bypass grafting. Vorapaxar is usually administered with other anticoagulants like acetylsalicylic acid and/or clopidogrel.

When a blood vessel is injured, platelets aggregate to form a plug and stop bleeding. Vorapaxar inhibits this aggregation and helps prevent clot formation. It belongs to a class of drugs called protease activated receptor-1 inhibitors. Vorapaxar binds to platelets and stops their aggregation induced by thrombin and thrombin receptor agonist peptide.

There are some warnings associated with vorapaxar. It should not be used in patients with a history of stroke, transient ischemic attack, or intracranial hemorrhage as it increases the risk of fatal bleeding. Vorapaxar should also not be used in patients with pathological bleeding like intracranial hemorrhage or peptic ulcers. The risk of bleeding should be considered before prescribing vorapaxar, especially in patients with advanced age, low body weight, history of bleeding disorders, impaired liver or kidney function, or use of certain medications.
