Terlipressin

Brand Names: Terlivaz

Drug Class: Vasopressin Receptor Agonist

Overview

11 DESCRIPTION TERLIVAZ contains terlipressin, a vasopressin receptor agonist. Terlipressin is a 12-amino acid peptide with the chemical name N -[ N -( N -glycylglycyl)glycyl]-8-L-lysinevasopressin. The structure of terlipressin acetate is shown below: Molecular formula: C 52 H 74 N 16 O 15 S 2 ∙ (C 2 H 4 O 2 ) n ; (n=number of acetate molecules; theoretical n=2.8) Average molecular weight: 1227.

Mechanism of Action

12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Terlipressin is a synthetic vasopressin analogue with twice the selectivity for vasopressin V 1 receptors versus V 2 receptors. Terlipressin acts as both a prodrug for lysine-vasopressin, as well as having pharmacologic activity on its own. Terlipressin is thought to increase renal blood flow in patients with hepatorenal syndrome by reducing portal hypertension and blood circulation in portal vessels and increasing effective arterial volume and mean arterial pressure (MAP). 12.2 Pharmacodynamics After administration of a single 0.

Dosage

2 DOSAGE AND ADMINISTRATION Prior to initial dosing, assess patients for ACLF Grade 3 and obtain patient baseline oxygenation level. Monitor patient oxygen saturation with pulse oximetry. ( 2.1 ) Recommended Dosage Regimen: ( 2.2 ) Days 1 to 3 administer TERLIVAZ 0.85 mg (1 vial) intravenously every 6 hours. Day 4: Assess serum creatinine (SCr) versus baseline. If SCr has decreased by at least 30% from baseline, continue TERLIVAZ 0.85 mg (1 vial) intravenously every 6 hours. If SCr has decreased by less than 30% from baseline, dose may be increased to TERLIVAZ 1.

Black Box Warning

WARNING: SERIOUS OR FATAL RESPIRATORY FAILURE TERLIVAZ may cause serious or fatal respiratory failure. Patients with volume overload or with acute-on-chronic liver failure (ACLF) Grade 3 are at increased risk [see References (15) ]. Assess oxygenation saturation (e.g., SpO 2 ) before initiating TERLIVAZ. Do not initiate TERLIVAZ in patients experiencing hypoxia (e.g., SpO 2

Contraindications

TERLIVAZ is contraindicated in patients with ongoing coronary, peripheral or mesenteric ischemia. TERLIVAZ is contraindicated: In patients experiencing hypoxia or worsening respiratory symptoms. ( 4 ) In patients with ongoing coronary, peripheral, or mesenteric ischemia. ( 4 )
