Desmopressin (DDAVP) and hemostasis.
Desmopressin is a widely used hemostatic drug. It is a synthetic analogue of the natural hormone vasopressin, but, in contrast to vasopressin, it has no pressor activity. The effect is immediate, with two- to sixfold increases in the plasma concentrations of coagulation factor VIII, on Willebrand factor, and tissue plasminogen activator, and increases in platelet adhesiveness of comparable magnitude. Desmopressin is used in patients with mild hemophilia A, von Willebrand's disease, congenital platelet dysfunction, or acquired platelet dysfunction due to uremia or intake of such drugs as aspirin. It may also be used to reduce surgical blood loss in patients without known bleeding diathesis. Optimal hemostatic effect is achieved with a dosage of 0.3 micrograms/kg given intravenously. Other routes of administration are subcutaneous injection or intranasal spray. The latter proved to be efficient for home treatment of patients with bleeding disorders.
