Which alternative medication is used in patients who have heparin-induced thrombocytopenia HIT )?
Patients with HIT are at high risk for thrombotic events and should be treated with alternative anticoagulants, typically a direct thrombin inhibitor (DTI). The US Food and Drug Administration (FDA) has approved the DTI argatroban (Acova) for prophylaxis and treatment of thrombosis in patients with HIT.
What are the non heparin anticoagulants?
The principal choices for a non-heparin anticoagulant are the direct thrombin inhibitors (DTIs): lepirudin, argatroban, and bivalirudin. DTIs are the treatment of choice for patients with known or suspected HIT.

Why is warfarin and heparin used together?
Warfarin. Warfarin (Coumadin®) is a pill for long-term anticoagulation. Heparin is usually given short-term, and warfarin is added in combination with heparin, before heparin is stopped. It can take 5-7 days (or longer) for the warfarin to reach an adequate level for it to be given alone.

What is the PTT for heparin?
Unlike most medications, the dose of heparin must be chosen according to the results of a blood test called the partial thromboplastin time (PTT).
