What is terlipressin used for?

Terlipressin, a vasopressin agonist, is a commonly used drug with different indications, particularly in patients with end-stage liver disease. As a V(1) receptor agonist, it increases systemic vascular resistance, particularly in the splanchnic area, resulting in a decrease of portal pressure.

Is terlipressin a vasodilator?

Terlipressin is a vasoconstrictor: it binds to the V₁ receptors of the vascular smooth muscle cells to cause vasoconstriction in both the systemic circulation and the splanchnic circulation. Terlipressin has also been shown to dilate intrahepatic vessels, thereby reducing intrahepatic resistance to portal inflow.

What is the mechanism of action of terlipressin acetate?

The exact mechanism of action of terlipressin is not fully understood; however, terlipressin works to cause vasoconstriction in shock and other conditions associated with vasodilation.

What is the mechanism of action of terlipressin HRS?

In HRS-AKI, terlipressin administration results in splanchnic vasoconstriction, shunting blood to the systemic circulation, reducing activation of the sympathetic nervous system and renin-angiotensin-aldosterone system, and blunting release of arginine vasopressin, ultimately enhancing renal perfusion.

What are the risks of terlipressin?

New recommendations following a recent clinical trial which found that in patients with type 1 hepatorenal syndrome terlipressin may cause serious or fatal respiratory failure at a frequency higher than previously known, and that terlipressin increases the risk of sepsis and septic shock.

When do you give terlipressin?

Terlipressin is indicated in the treatment of bleeding oesophageal varices. The administration of terlipressin serves the emergency care for acute bleeding oesophageal varices until endoscopic therapy is available.

What class of drug is terlipressin?

Terlipressin is a vasopressin receptor agonist. Terlipressin was approved for medical use in the United States in 2022. The US Food and Drug Administration (FDA) considers it to be a first-in-class medication.

Does terlipressin lower blood pressure?

Terlipressin works selectively on (V1) receptors in the vascular smooth muscle in the splanchnic vessels, causing vasoconstriction as well as a decline flow to the splanchnic blood flow, declined portal blood flow, thereby causing decreased portal blood pressure as well as improved systemic hemodynamics [6].

Is terlipressin an antidiuretic?

The vasopressin analog terlipressin is believed to cause vasoconstriction selectively by V1 receptor stimulation. However, a possible antidiuretic effect by V2 receptor stimulation has never been ruled out.

Is terlipressin a vasopressin?

Terlipressin (tricyl-lysine vasopressin) is a synthetic analogue of vasopressin. As a compound it is rapidly metabolized by endopeptidases to form the vasoactive lysine vasopressin. The half-life of terlipressin is 6 hours whereas that of vasopressin is only 6 min.

Is terlipressin a vasopressor?

Vasopressin and its analogue, terlipressin, are potent vasopressors that may be useful therapeutic agents in the treatment of cardiac arrest, septic and catecholamine-resistant shock and oesophageal variceal haemorrhage.

Is terlipressin used for shock?

A single dose of terlipressin (1-2 mg) increases systemic blood pressure within 10 to 20 min in patients with septic shock. This improvement in blood pressure is sustained for at least 5 h (²¹).

Can terlipressin be given every 4 hours?

BEST PRACTICE ADVICE 7: Terlipressin should be initiated as a bolus dose of 1 mg every 4-6 hours (total 4-6 mg/d). The dose should be increased to a maximum of 2 mg every 4-6 hours (total 8-12 mg/d) if there is no reduction in serum creatinine at day 3 of therapy by at least 25% compared to the baseline value.

Can terlipressin cause bradycardia?

After bleeding is controlled, it may be administered at a lower dose of 1 mg ever 4 h for up to 5 days [7]. Adverse effects of terlipressin are usually mild and include skin pallor, headache, abdominal pain, bradycardia, hypertension and hyponatremia.

What is terlipressin in type 1 HRS?

The FDA-approved indication of terlipressin is in HRS with rapid reduction in kidney function. This corresponds to historical definitions of HRS Type 1, which has been defined as a sudden impairment of kidney function, specifically a 100% increase in serum creatinine to a value >2.5 mg/dL within <2 weeks.

Does terlipressin affect heart rate?

The effect on cardiac function of a single bolus injection of terlipressin 2 mg has been assessed in 20 patients with cirrhosis and ascites [92^c]. Terlipressin increased mean arterial pressure by 17 (95% CI = 11, 24) mmHg and heart rate fell by 11 (7, 16) beats/minute.

Does terlipressin affect urine output?

Reduction of the high-dose norepinephrine was observed in all patients ( p<0.05). Conclusions: Our findings showed that, in patients with norepinephrine-treated septic shock, terlipressin increased GMP, urine output and creatinine clearance by an increase in mean arterial pressure.

What is the antidote for terlipressin?

Although there is no specific antidote to reverse terlipressin-induced peripheral cyanosis, the effective managements are to diminish the dosage of terlipressin, shift the administrating method from intravenous bolus to intravenous infusion, monitor daily dose plus patients' conditions closely, prevent occurrence of ...
