Vasopressin analogues and V1a receptor agonists in septic shock
Abstract:
This article reviews the role of arginine-vasopressin and the vasopressin analogue terlipressin as potent alternative vasoconstrictors in the treatment of fluid and catecholamine-refractory septic shock. Terlipressin is the most selective, clinically available V1 receptor agonist, and may be more potent than arginine-vasopressin in restoring catecholamine refractory septic shock. Recent experimental and clinical studies on terlipressin, as well as the possible benefit of selective V1a receptor agonists, are discussed.

Adrenergic Agonists: Therapeutic Uses
Emergency and Intensive Care Unit (ICU) applications: Pressor agents increase blood pressure, heart rate, and contractility in shock and organ failure situations. Dopamine can induce vasodilation and stimulate adrenoceptors. Endogenous catecholamines are effective in treating cardiogenic shock. α2-agonists like clonidine can reverse anesthesia-induced hypertension.
