Terlipressin is a dodecapeptide that has three glycyl residues attached to the N-terminal of lysine vasopressin (LVP). As ADH (which is also known as vasopressin) causes direct water reabsorption from the kidney tubules, salts and wastes are concentrated in what will eventually be excreted as urine. It causes narrowing of blood vessels (vasoconstriction), thereby limiting blood flow to a particular area of the body. Vasopressin acts by direct stimulation of smooth muscle V 1 receptors. The effects are useful in nerve blocks and infiltration anaesthesia but not in epidural or spinal. It is possible that better short-term survival comes at the cost of worse long-term outcomes. It is capable of inducing diuresis depending on the clinical condition of the patient. Animal experiments suggest that the metabolism of vasopressin is primarily by liver and kidney. Synthetic analogue of vasopressin with prompt onset and longer, more specific antidiuretic action; desmopressin increases water permeability in renal tubular cells, which in turn decreases urine volume and increases urine osmolality View 4th_Semester_Pharm review 1.docm from NUR 615 at Barry Univesity.
