Argatroban, a direct thrombin inhibitor, has been used in Japan since the e
arly 1980's and was recently approved for use in the United States for pati
ents with heparin-induced thrombocytopenia. However, its use has been studi
ed in other clinical settings including, myocardial infarction, percutaneou
s coronary intervention and cerebral thrombosis. The doses used in the diff
erent clinical situations vary, but argatroban offers the advantage of not
requiring renal adjustment. Because of its small molecular weight, argatrob
an has the ability to inhibit both clot bound and soluble thrombin. This pa
per provides a comprehensive review of both indicated and off label uses of
argatroban. Pharmacology, pharmacokinetics, adverse events and drug intera
ctions with argatroban are also discussed.
