Terlipressin is a synthetic analogue of vasopressin used in emergency management of variceal haemorrhage and hepatorenal syndrome (HRS).
⚙️ Mode of Action
🔒 V1 receptor agonist → potent vasoconstrictor.
⬇️ Increases systemic vascular resistance, especially in the splanchnic circulation, reducing portal venous pressure.
🩸 Leads to haemostasis in variceal bleeding.
💧 Has antihaemorrhagic and mild antidiuretic effects.
💊 Indications / Dose
Acute oesophageal variceal bleed 🩸:
1–2 mg IV bolus, then 1 mg IV every 4–6 hours for up to 72 hours (or until bleeding controlled).
Type 1 Hepatorenal Syndrome (HRS) 🧫:
Improves renal perfusion and function, often combined with IV albumin. Acts as a bridge to liver transplantation and may improve survival.
