Abstract

The efficacy and safety of heparin and low-molecular-weight heparins (LMWHs) are well documented in venous and arterial thromboembolism. Several drawbacks of heparins have inspired the development of newer parenteral anticoagulants for specific indications, including heparin-induced thrombocytopenia (HIT) and percutaneous coronary interventions (PCI). The direct thrombin inhibitors recombinant hirudin and argatroban are now established alternatives for HIT patients, and bivalirudin is one of the most used anticoagulants in PCI. The pentasaccharide fondaparinux is an alternative for LMWH for thromboprophylaxis in various clinical settings and for patients with an acute coronary syndrome (ACS) not scheduled for PCI. In Europe, it was recently approved for treatment of superficial vein thrombosis. Further development of new parenteral anticoagulants is slow and the emphasis has shifted towards development of new oral anticoagulants and antiplatelet drugs. Still, promising new anticoagulants, some targeting less conventional targets in the coagulation system, have been developed and will undergo further clinical evaluation.

Summary

Comprehensive review of newer parenteral anticoagulants including recombinant hirudin, argatroban (HIT), bivalirudin (PCI), fondaparinux (ACS, VTE prophylaxis, superficial vein thrombosis); positions hirudin-class in the post-NOAC landscape.

Why This Matters for Hirudotherapy

This review discusses newer parenteral anticoagulants for arterial and venous thromboembolism, including HIT and PCI. It explicitly states that recombinant hirudin and argatroban are established alternatives for HIT patients, while bivalirudin is one of the most used anticoagulants in PCI. Because the abstract directly addresses recombinant hirudin, it has some relevance to the hirudin-focused interests of ASH, though it does not mention leeches, leech saliva, or hirudotherapy itself. The key limitation is that the article is a review of pharmaceutical anticoagulant trends, and it does not evaluate live leech therapy or clinical hirudotherapy outcomes.
