- [SIADH and vaptans].
ZUSAMMENFASSUNG
The vaptans are non-peptide arginine-vasopressin-receptor antagonists, that are orally and intravenously active. A few vaptans have undergone sufficient clinical development to be on the market. In the EU only tolvaptan is accepted to treat hyponatremia related to SIADH. The place of this new treatment is compared with water restriction, demeclocyclin, furosemide and urea.
