Desmopressin stimulates bile secretion in anesthetized rats.

One of the synthetic analogues of antidiuretic hormone-desmopressin is used in patients with central diabetes insipidus and in those with coagulation disorders. However, its effects on bile secretion are not fully defined. We investigated the effect of desmopressin on bile formation and determined the role of V1a vasopressin receptors in the action of desmopressin on choleresis.
