Bivalirudin (Bivalitroban), sold under the brand names Angiomax and Angiox and manufactured by The Medicines Company, is a direct thrombin inhibitor (DTI).Chemically, it is a synthetic congener of the naturally occurring drug hirudin, found in the saliva of the medicinal leech Hirudo medicinalis. Bivalirudin lacks many of the limitations seen with indirect thrombin inhibitors, such as heparin. A short, synthetic peptide, it is a potent and highly specific inhibitor of thrombin that inhibits both circulating and clot-bound thrombin, while also inhibiting thrombin-mediated platelet activation and aggregation. Bivalirudin has a quick onset of action and a short half-life. It does not bind to plasma proteins (other than thrombin) or to red blood cells. Therefore, it has a predictable antithrombotic response. There is no risk for heparin-induced thrombocytopenia or heparin-induced thrombosis-thrombocytopenia syndrome. It does not require a binding cofactor such as antithrombin and does not activate platelets. These characteristics make bivalirudin an ideal alternative to heparin. Bivalirudin clinical studies demonstrated consistent positive outcomes in patients with stable angina, unstable angina (UA), non–ST-segment elevation myocardial infarction (NSTEMI), and ST-segment elevation myocardial infarction (STEMI) undergoing PCI in seven major randomized trials. Patients receiving bivalirudin had fewer adverse events compared to patients that received heparin. Indications
US (United States)
Bivalirudin is indicated for use as an anticoagulant in patients with unstable angina undergoing percutaneous transluminal coronary angioplasty (PTCA). Bivalirudin with provisional use of glycoprotein IIb/IIIa inhibitor (GPI) is indicated for use as an anticoagulant in patients undergoing percutaneous coronary intervention (PCI).
Sometimes the linear foreign body anchors in the mouth by catching under the tongue. Pantyhose is a common linear foreign body in dogs. References
