Vasopressin is a more potent alpha-1 agonist than norepinephrine at equivalent doses Vasopressin acts on V1 receptors independently of adrenergic receptors, compensating for relative vasopressin deficiency in septic shock Vasopressin has positive inotropic effects that improve cardiac output in septic shock Vasopressin is preferred in septic shock because it does not increase myocardial oxygen demand
