Clinical Trial Summary

Elderly subjects are at greater risk of thrombophlebitis than the general population, but also of bleeding when anticoagulant therapy is initiated. Enoxaparin is one of the most widely used anticoagulants in the management of venous thromboembolism in the world. Its use is not codified in the elderly, because too few studies have been carried out in people over 75 years old. For several years, Enoxaparin in curative treatment has been administered at a reduced dosage of 4000 IU twice a day (and not at a standard dose of 100 IU / kg) at the Geriatrics center of the CRHU in Strasbourg with the clinical impression of a reduction the risk of serious bleeding without reduction in therapeutic efficacy in this very elderly population. Confirmation of a reduction in the risk of bleeding at this dosage could be the start of a change in prescribing practices, towards a more suitable dosage in the elderly.
