Desmopressin
Definition: A synthetic vasopressin analog used clinically for central diabetes insipidus, nocturia in selected patients, and certain bleeding disorders.
What is Desmopressin?
Desmopressin is a modified peptide analog of arginine vasopressin designed to increase antidiuretic activity while reducing vasoconstrictive V1 receptor effects. It is widely used as a prescription medication in endocrinology, nephrology, urology, and hematology.
How does Desmopressin work?
Desmopressin selectively activates V2 receptors in the kidney collecting ducts, increasing aquaporin-2 insertion and water reabsorption. It also stimulates release of von Willebrand factor and factor VIII from endothelial stores, explaining its role in selected bleeding disorders.
Primary Documented Uses
- Central diabetes insipidus treatment
- Nocturnal enuresis and selected adult nocturia under monitoring
- Mild hemophilia A and type 1 von Willebrand disease bleeding prophylaxis
- Diagnostic testing of renal concentrating ability in selected settings
Research Summary
Clinical evidence supports desmopressin for central diabetes insipidus and carefully selected nocturia or nocturnal enuresis patients. It can also reduce bleeding in mild hemophilia A and type 1 von Willebrand disease. The major safety concern is hyponatremia, especially when fluid intake is not restricted appropriately.
Legal and Regulatory Status
Desmopressin is FDA-approved as a prescription medication. It requires careful dosing and sodium monitoring in at-risk patients because severe hyponatremia can be dangerous.
