Desmopressin Acetate - Brands
By mimicking the actions of endogenous ADH, desmopressin acts as a selective agonist of V2 receptors expressed in the renal collecting duct (CD) to increase water re-absorption and reduce urine production. Desmopressin has been shown to be more potent than ADH in increasing plasma levels of factor VIII activity in patients with hemophilia and von Willebrand's disease Type I. Desmopressin demonstrates markedly diminished pressor activity. Desmopressin administered intranasally has an antidiuretic effect about one-tenth that of an equivalent dose administered by injection.
Upon binding of desmopressin to V2 receptors in the basolateral membrane of the cells of the distal tubule and collecting ducts of the nephron, adenylyl cyclase is stimulated. The resulting intracellular cascades in the collecting duct lead to increased rate of insertion of water channels, called aquaporins, into the lumenal membrane and enhanced the permeability of the membrane to water.
