Identification
Name Tirofiban
Accession Number DB00775 (APRD00304)
Type small molecule
Description Tirofiban prevents the blood from clotting during episodes of chest pain or a heart attack, or while the patient is undergoing a procedure to treat a blocked coronary artery. It is a non-peptide reversible antagonist of the platelet glycoprotein (GP) IIb/IIIa receptor, and inhibits platelet aggregation.

Monoisotopic Weight 440.234492962
Pharmacology
Indication For treatment, in combination with heparin, of acute coronary syndrome, including patients who are to be managed medically and those undergoing PTCA or atherectomy.
Mechanism of action Tirofiban is a reversible antagonist of fibrinogen binding to the GP IIb/IIIa receptor, the major platelet surface receptor involved in platelet aggregation. Platelet aggregation inhibition is reversible following cessation of the infusion of tirofiban.
Absorption Not Available
Protein binding 65%
Biotransformation Metabolism appears to be limited.
Route of elimination It is cleared from the plasma largely by renal excretion, with about 65% of an administered dose appearing in urine and about 25% in feces, both largely as unchanged tirofiban.
Toxicity Not Available
Affected organisms
  • Humans and other mammals

Drug Interactions
Drug Mechanism of interaction
Abciximab Additive effects. Concomitant use is contraindicated.
Eptifibatide Additive effects. Concomitant use is contraindicated.
Ginkgo biloba Additive anticoagulant/antiplatelet effects may increase bleed risk. Concomitant therapy should be avoided.
Treprostinil The prostacyclin analogue, Treprostinil, increases the risk of bleeding when combined with the antiplatelet agent, Tirofiban. Monitor for increased bleeding during concomitant thearpy.
