Vasopressin analogues are chemicals similar in function but not necessarily similar in structure to vasopressin (ADH), such as desmopressin.
Vasopressin analogues... used therapeutically in various conditions, and its long-acting synthetic analogue desmopressin is used in conditions featuring low vasopressin secretion
