What Is Argatroban?

If you have a condition known as heparin-induced thrombocytopenia (HIT), your healthcare provider may prescribe argatroban.
 But what is argatroban and how does it work?
 
Argatroban is used to prevent and treat blood clots in people who have HIT, a potentially dangerous reaction that sometimes occurs due to heparin or heparin-like medications. It can also be used as a "blood-thinning" medicine in people who have to undergo angioplasty procedures and have HIT or are at risk for this reaction.
 
Although argatroban does not break down blood clots, it can slow down the formation of clots so the body has a chance to break them down naturally. As a type of direct thrombin inhibitor, argatroban works by blocking the actions of thrombin, a naturally occurring protein in the body that encourages clot formation. By inhibiting thrombin, argatroban helps to prevent the formation of blood clots.
