Identification
Name Terlipressin
Accession Number DB02638 (EXPT03310)
Type small molecule
Description Terlipressin is an analogue of vasopressin used as a vasoactive drug in the management of hypotension. It has been found to be effective when norepinephrine does not help. [Wikipedia]

Pharmacology
Indication Commonly used to stop bleeding of varices in the food pipe (oesophagus).
Mechanism of action Terlipressin, an analogue of vasopressin, acts on three different receptors, vasopressin receptor V1a (which initiates vasoconstriction, liver gluconeogenesis, platelet aggregation and release of factor VIII), vasopressin receptor V1b (which mediates corticotrophin secretion from the pituitary) and vasopressin receptor V2 which controls free water reabsorption in the renal medullar. The binding of terlipressin to the V2 receptor activates adenylate cyclase which causes the release of aquaporin 2 channels into the cells lining the renal medullar duct. This allows water to be reabsorbed down an osmotic gradient so the urine is more concentrated.
