Desmopressin

DDAVP, 1-deamino-8-D-arginine vasopressin

Research useEducational entry
Mechanism

A synthetic analogue of the antidiuretic hormone vasopressin. It selectively activates renal V2 receptors, raising cAMP and inserting aquaporin-2 water channels in the collecting duct to concentrate urine; it also triggers release of von Willebrand factor and factor VIII from endothelial stores.

Evidence

Well-characterised human clinical evidence, in use since the late 1970s. An approved prescription medicine, not a research-use compound.

Applications
  • Approved for central (cranial) diabetes insipidus
  • Primary nocturnal enuresis
  • Bleeding support in type 1 von Willebrand disease and mild haemophilia A
  • Studied for nocturia/nocturnal polyuria
Protocol

Educational overview only — no dosing instructions in the public hub. Prescription-only medicine used under medical supervision with fluid-intake precautions.

Risks

Main risk is dilutional hyponatremia (low blood sodium), which can cause seizures — the reason intranasal desmopressin is no longer marketed for bedwetting; risk is higher in older adults and requires fluid restriction and sodium monitoring. Response in von Willebrand disease can wane with repeated dosing (tachyphylaxis).

Quality

A regulated pharmaceutical product; authenticity means a licensed, pharmacy-dispensed drug, not a research-grade vial. Third-party CoA (purity + quantification + MS) is the minimum verification for any non-pharmaceutical source.

Legal status

Approved prescription medicine (US FDA initial approval 1978; approved across the EU); dispensed only on prescription.
