Answer

Posterior Pituitary Hormones

Agents in this category cause contraction of smooth muscle of all parts of the vascular bed, especially the small arterioles, capillaries, and venules, with less effect on the smooth musculature of the large veins.

Vasopressin (Pitressin)

Vasopressin has vasopressor and antidiuretic hormone (ADH) activity. It promotes smooth muscle contraction throughout the vascular bed of the renal tubular epithelium (vasopressor effects). Vasoconstriction is increased in splanchnic, portal, coronary, cerebral, peripheral, pulmonary, and intrahepatic vessels.
