Tirofiban (Tir)
Tirofiban is an antiplatelet drug. It belongs to a class of antiplatelet named glycoprotein IIb/IIIa inhibitors. Tirofiban is the first drug candidate whose origins can be traced to a pharmacophore-based virtual screening lead. Tirofiban is a synthetic, non-peptide inhibitor acting at glycoprotein (GP) IIb/IIIa receptors in human platelets. It therefore constitutes an anticoagulant, specifically an inhibitor of platelet aggregation. Tirofiban has been demonstrated to cross the placenta in pregnant rats and rabbits. Although the doses employed in these studies were a multiple of those used in human beings no adverse effects on the offspring in both animals have been seen. However, there are no adequate and well controlled studies in pregnant women. Therefore, tirofiban should be used during pregnancy only if clearly indicated.
