The use of haemostatic drugs in haemophilia: desmopressin and antifibrinolytic agents.
Over the last 4 decades, there have been very significant advances in the treatment of haemophilia. Plasma products first became available in the 1960s, beginning with cryoprecipitate and then intermediate-purity plasma concentrates, for the treatment of haemophilia A and B. The disasters of viral infections amongst people with haemophilia in the 1980s served to stimulate both the development of techniques of viral inactivation of concentrates and the manufacture of purer products. We therefore now have safe plasma products that are also pure in that they are concentrates of only the deficient protein responsible for the congenital coagulopathy. Preparations of specific coagulation proteins obtained using recombinant biotechnology techniques have been available since 1995. By contrast, pharmacological options for the treatment of the haemophilia remain very limited. The only therapeutic alternatives of real practical value which have been available in the last 30 years for the treatment of haemophilic patients are desmopressin, antifibrinolytic agents, aprotinin, concentrated oestrogens, and local haemostatic agents such as topical thrombin or fibrin glue. This article aims to assess the pharmacological basis and accumulated experience relating to these drugs when used for the prevention and treatment of bleeding in patients with haemorrhagic disorders.
