1. Regulation of Portal Venous Circulation and Balance of Vascular Tone
It possesses specific vasoactive properties, enabling it to act on the visceral microcirculatory system; it modulates the contractile state of intra-abdominal vascular smooth muscle, regulates blood flow distribution within portal vein branches, and optimizes hemodynamic pathways in the visceral region. Compared to naturally occurring endogenous substances, this compound exhibits greater molecular stability and a longer duration of action, resulting in a smoother hemodynamic response. It contributes to the regulation of physiological states associated with portal venous pressure and helps maintain the dynamic balance of visceral organ perfusion. Hepatic dysfunction is often accompanied by alterations in portal venous flow dynamics that can compromise circulatory stability; by modulating blood flow velocity and distribution-and regulating visceral circulatory pathways-this compound mitigates the risk of fluctuations in vascular pressure. Its activity is primarily concentrated within the visceral vasculature, with relatively limited effects on superficial or central surface vessels; balancing selectivity and physiological stability, it functions as a vasoactive peptide involved in maintaining visceral vascular homeostasis.
2. Renal Metabolic Regulation and the Maintenance of Water-Salt Homeostasis

As a peptide derived from vasopressin, it exhibits functional characteristics similar to those of the endogenous hormone; it acts on regulatory sites in the renal collecting ducts to modulate water and electrolyte metabolism, thereby maintaining the relative stability of body fluid osmolality. This compound influences local renal microcirculation, thereby improving renal blood supply and metabolic efficiency, facilitating the normal transport and excretion of metabolites, and supporting basic renal physiological functions. When changes in visceral circulation threaten body fluid balance-often accompanied by fluctuations in water distribution and electrolyte concentrations-the compound helps correct metabolic imbalances and maintains the relative stability of water and salt distribution. Furthermore, owing to its stable physicochemical properties and minimal impact on native cellular structures, it leverages its biocompatibility to align with physiological rhythms, exerting a sustained regulatory effect within the urinary metabolic system to maintain overall body fluid homeostasis.

3. Regulation of Systemic Vascular Tone and Circulatory Hemodynamic Balance

It acts on the systemic peripheral vascular tone system to a certain extent, participating in the regulation of vasomotor status and influencing baseline vascular resistance; it thereby contributes to the maintenance and regulation of physiological fluctuations in blood pressure. It primarily targets the splanchnic vasculature, indirectly influencing global hemodynamic distribution through local circulatory changes and helping to stabilize blood flow to vital organs such as the heart, lungs, and kidneys. Compared to potent vasoactive agents, its action is relatively gradual-minimizing the risk of abrupt hemodynamic shifts-and supports the maintenance of circulatory dynamic equilibrium. It also plays a role in regulating microcirculatory function, mitigating cardiovascular strain caused by hemodynamic fluctuations, and helping maintain a stable overall circulatory rhythm. With its prolonged duration of action, it contributes to circulatory homeostasis at a mechanistic level, serving as a representative regulatory agent among vasoactive peptides.

1. Mechanism of Visceral Vascular Regulation

Leveraging its polypeptide molecular structure, it binds to specific receptors on the cell membranes of visceral vascular smooth muscle cells. By participating in intracellular signal transduction and modulating the contractile rhythm of these smooth muscle cells, it regulates vascular tone within the abdominal viscera. The drug exhibits selective receptor affinity, preferentially acting on vessels associated with the mesenteric and portal venous systems while having a relatively limited direct impact on coronary and cerebral arteries; consequently, it modulates the contractile state of visceral capacitance vessels and alters local blood flow distribution. Its modified structure confers enhanced stability and a longer duration of action in vivo compared to natural vasopressin, resulting in a more gradual change in vascular tone and helping to maintain hemodynamic stability. This mechanism modulates blood flow distribution within the visceral microcirculation and influences portal hemodynamics, thereby mitigating fluctuations in local vascular resistance; however, its overall effect remains a physiological regulatory process characterized by receptor-dependent selectivity.

2. Regulatory Mechanisms of Water and Salt Metabolism

Terlipressin, a peptide structurally analogous to vasopressin, acts on specific receptor sites associated with the renal collecting ducts. It modulates intracellular osmotic signaling pathways, thereby influencing the physiological processes governing water reabsorption. Through receptor-mediated mechanisms, it affects the transport activity of aquaporins. It alters the water permeability of renal tubules, thereby modulating water reabsorption and helping maintain the dynamic equilibrium of body fluid osmolality. Additionally, it may indirectly influence the transport of electrolytes such as sodium and potassium, thereby contributing to the regulation of ionic gradients. Due to structural modifications, it exhibits enhanced resistance to enzymatic degradation, resulting in a more sustained signaling effect compared to endogenous vasopressin and promoting greater stability in the regulation of water and salt metabolism. Its action involves modulation of renal water and electrolyte transport rather than a unidirectional functional shift, and it plays a physiologically relevant role in maintaining body fluid homeostasis.

3. Mechanism of Systemic Circulatory Homeostasis Regulation

By leveraging the distribution characteristics of systemic vascular receptors, it can modulate peripheral vascular resistance to a certain extent, thereby contributing to the regulation of the body's overall hemodynamic distribution. Its primary site of action is the splanchnic vasculature; by regulating local vasoconstriction, it indirectly influences systemic circulatory resistance, facilitating dynamic adjustments in blood flow distribution among organs. The drug's signaling process has a gradual onset, avoiding abrupt fluctuations in blood flow; this results in relatively smooth hemodynamic changes, which help maintain cardiovascular system stability. Furthermore, by modulating the release rhythms of endogenous vasoactive factors, it may also participate in circulatory feedback regulation, thereby indirectly influencing hemodynamic balance. Overall, this mechanism primarily functions through regulation of vascular tone and circulatory distribution-rather than a unidirectional process of enhancement or repair-holding physiological significance for the maintenance of systemic circulatory dynamic equilibrium.
