Mechanism of action
- 1.Stimulates V1 receptors on vascular smooth muscle, constricting the splanchnic arterial bed.
- 2.Lowering splanchnic inflow reduces portal pressure, which is why it is used in variceal bleeding.
- 3.Improves effective arterial blood volume, which restores renal perfusion in hepatorenal syndrome.
- 4.The glycine residues act as a slow-release depot, so one dose lasts hours.
- 5.Has little V2 activity, so it does not concentrate urine the way desmopressin does.
Studied for
- Hepatorenal syndrome type 1
- Acute variceal bleeding
- Refractory ascites (investigational)
- Septic shock as an adjunct vasopressor (off-label research)
Reported effects
- Reversal of hepatorenal syndrome in roughly a third to a half of patients when combined with albumin in trials
- Reduced portal pressure and better control of variceal bleeding
- Improved renal function markers over days
- Ischaemic complications, including skin and bowel ischaemia
Side effects
- Abdominal pain and ischaemic skin necrosis
- Peripheral or gut ischaemia
- Hyponatraemia
- Fluid overload and pulmonary oedema
- Bradycardia
- Respiratory failure was reported more often than placebo in the CONFIRM trial
Research protocol
Research context only - a hospital medicine. In hepatorenal syndrome trials terlipressin was given as 0.85 to 1 mg intravenously every four to six hours, escalated when needed toward a maximum of about 12 mg per day, alongside albumin, for up to 14 days; variceal bleeding regimens typically use 1 to 2 mg every four to six hours for two to five days with close monitoring for ischaemia.
Research context only
Evidence justification
Randomised trials in hepatorenal syndrome (OT-0401 and CONFIRM) are modest in size, show real benefit but also meaningful adverse events, and are supported by long use in variceal bleeding.
