Bivalirudin.
Review published in Thrombosis and haemostasis (2008)
Abstract
Bivalirudin is a direct thrombin inhibitor (DTI) frequently used for anticoagulation in the setting of invasive cardiology, particularly percutaneous coronary intervention (PCI). Bivalirudin has a unique pharmacologic profile: unlike other marketed DTIs, it undergoes predominant non-organ elimination (proteolysis), and has the shortest half-life (approximately 25 min). Its affinity for thrombin is intermediate between that of lepirudin (highest) and argatroban (lowest)--this helps explain why it interferes with functional clotting assays to an extent intermediate between that achieved by these two other DTIs. This effect is best known for the PT (INR)--higher affinity for thrombin corresponds to lower molar DTI requirements to prolong the APTT; in turn, lower concentrations required for APTT prolongation (and, presumably, in-vivo effect) result in reduced PT (INR) prolongation. Bivalirudin is primarily used for its first FDA-approved indication, namely anticoagulation during percutaneous transluminal coronary angioplasty ("balloon angioplasty"), the most frequent type of PCI. Bivalirudin is also indicated for PCI with provisional use of glycoprotein IIb/IIIa antagonist therapy, and for patients with, or at risk of, heparin-induced thrombocytopenia (HIT), or HIT with thrombosis syndrome (HITTS), undergoing PCI. The bivalirudin development program has used a "quadruple" endpoint comprising a "triple" efficacy endpoint plus major bleeding - this approach anticipated the subsequent emphasis on strategies to improve clinical outcomes through bleeding reduction. Besides summarizing the key trials evaluating bivalirudin use for acute coronary syndrome (especially employing PCI), we review also the studies of bivalirudin as anticoagulant for "on-" and "off-pump" cardiac surgery, including both HIT and non-HIT situations.

Por qué esto importa para la hirudoterapia
Esta revisión resume la farmacología y el desarrollo clínico de la bivalirudina, un inhibidor directo de la trombina modelado a partir de la hirudina — el anticoagulante característico de la saliva de la sanguijuela medicinal. Detalla la afinidad intermedia de la bivalirudina por la trombina (entre la lepirudina y el argatrobán), su vida media corta (~25 min), su eliminación no orgánica mediante proteólisis, y sus indicaciones aprobadas por la FDA para la intervención coronaria percutánea y la trombocitopenia inducida por heparina. Para ASH, esta revisión es muy pertinente porque rastrea directamente un importante anticoagulante clínico hasta su inspiración estructural derivada de la sanguijuela y lo compara con otros agentes basados en la hirudina. ADVERTENCIA: El artículo se centra por completo en el fármaco bivalirudina y los IDT sintéticos relacionados; no aborda la hirudoterapia con sanguijuelas vivas, los extractos salivales crudos ni otros componentes del secretoma de la sanguijuela más allá del legado estructural de la hirudina.
