Indeed, it was shown that vasopressin is amore potent vasoconstrictor thanangiotensin II or norepinephrine and is capable of increasing systemic vascular resistance in doses less than those required to produce maximum urine concentration. Does vasopressin dilate or constrict? In general, vasopressin decre...

Vasopressin does not constrict the pulmonary circulation, and thus vasopressin may be preferred for patients with pulmonary hypertension. In this respect vasopressin differs from NOS inhibitors. It is hoped that, unlike early trials of NOS inhibition in sepsis, vasopressin's more favorable hemodynamic ...
Vasopressin increased nasal vascular resistance on the side of injection with no changes in the systemic arterial blood pressure or secretion by the lateral nasal gland. Nasal airflow resistance did not change significantly. Thus desmopressin dilates the nasal vascular bed and vasopressin constricts it...
