| ADME/Pharmacokinetics |
Absorption, Distribution and Excretion Following a 1 mg IV injection of terlipressin acetate in patients with HRS-1, the median Cmax, AUC24h and Cave of terlipressin at steady-state were 70.5 ng/mL, 123 ng × hr/mL and 14.2 ng/mL, respectively. The median Cmax, AUC24h and Cave of lypressin were 1.2 ng/mL, 11.2 ng × hr/mL and 0.5 ng/mL, respectively. Terlipressin and lypressin exhibit linear pharmacokinetics in healthy subjects. Plasma concentrations of terlipressin demonstrate proportional increases with the dose administered. Less than 1% of terlipressin and <0.1% of lysine-vasopressin is excreted in urine in healthy subjects. The volume of distribution of terlipressin was 6.3 L and 1370 L for lysine-vasopressin. The clearance of terlipressin was 27.4 L/hr and 318 L/hr for lysine-vasopressin. Clearance of terlipressin in HRS-1 patients increased with body weight, while body weight had no effect on the clearance of lysine-vasopressin. Metabolism / Metabolites The N-terminal glycyl residues of terlipressin is cleaved by various tissue peptidases to release its pharmacologically active metabolite, [lypressin] or lysine-vasopressin. Once formed, lypressin is undergoes various peptidase-mediated metabolic pathways in body tissues. Terlipressin is not metabolized in the blood or plasma. Due to the ubiquitous nature of peptidases in body tissues, it is unlikely that the metabolism of terlipressin will be affected by disease state or other drugs. Biological Half-Life The terminal half-life of terlipressin was 0.9 hours and 3.0 hours for lysine-vasopressin. |

| Additional Infomation |
Pharmacodynamics Terlipressin mimics the biological effects of endogenous vasopressin, but it displays increased selectivity for the V1 receptor and a longer half-life than vasopressin. These pharmacokinetic and molecular properties of terlipressin give it several advantages, such as the prevention of rebound hypotension when the drug is stopped and convenience in patients with limited intravenous access. Terlipressin increases arterial pressure (diastolic, systolic, and mean) and decreases heart rate in patients with hepatorenal syndrome type 1 (HRS-1). After the administration of a single 0.85 mg dose of terlipressin in patients with HRS-1, cardiovascular effects were observed within five minutes after dosing and were maintained for at least six hours after dosing. The maximum change in blood pressure and heart rate occurred at 1.2 to two hours post-dose. |
