Absorption, Distribution and Excretion
In HRS-1 patients, following intravenous administration of 1 mg terlipressin acetate, the median Cmax, AUC24h, and Cave at steady state for terlipressin were 70.5 ng/mL, 123 ng × hr/mL, and 14.2 ng/mL, respectively. The median Cmax, AUC24h, and Cave for lisiopressin were 1.2 ng/mL, 11.2 ng × hr/mL, and 0.5 ng/mL, respectively. Both terlipressin and lisiopressin exhibited linear pharmacokinetic characteristics in healthy subjects. Plasma concentrations of terlipressin increased proportionally to the administered dose. Less than 1% of terlipressin and less than 0.1% of lysine vasopressin were excreted in the urine of healthy subjects. The volume of distribution for terlipressin was 6.3 L, and for lysine vasopressin, it was 1370 L. Terlipressin has a clearance rate of 27.4 L/hr, while lysine vasopressin has a clearance rate of 318 L/hr. In HRS-1 patients, terlipressin clearance increases with body weight, while body weight has no effect on lysine vasopressin clearance. Metabolism/Metabolites: The N-terminal glycyl residue of terlipressin is cleaved by various tissue peptidases, releasing its pharmacologically active metabolite, lysine vasopressin (LV). After its formation, LV undergoes various peptidase-mediated metabolic pathways in tissues throughout the body. Terlipressin is not metabolized in blood or plasma. Because peptidases are ubiquitous in human tissues, the metabolism of terlipressin is unlikely to be affected by disease states or other drugs. Biological Half-Life: The terminal half-life of terlipressin is 0.9 hours, and that of lysine vasopressin is 3.0 hours. |

Pharmacodynamics
Terlipressin mimics the biological effects of endogenous vasopressin, but it exhibits greater selectivity for V1 receptors and a longer half-life. These pharmacokinetic and molecular properties of terlipressin offer several advantages, such as prevention of rebound hypotension after discontinuation and ease of use in patients with limited intravenous access. Terlipressin increases arterial pressure (diastolic, systolic, and mean arterial pressure) and decreases heart rate in patients with hepatorenal syndrome type 1 (HRS-1). In HRS-1 patients, cardiovascular effects are observed within 5 minutes of a single administration of 0.85 mg terlipressin and last for at least 6 hours. The greatest changes in blood pressure and heart rate occur between 1.2 and 2 hours after administration. |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
