title: Indomethacin potentiates the vasoconstrictor actions of angiotensin II in normal man.
abstract: The blood pressure response to graded infusions of angiotensin II was assessed under control conditions and following short term (16 hour) indomethacin treatment utilizing normal men equilibrated on a constant diet of normal sodium and potassium content. Although basal mean blood pressure was unchanged, the increase in blood pressure with all rates of angiotensin II infusion ranging from 200 to 1000 ng/min was significantly greater with indomethacin treatment. Pre-infusion body weight and plasma renin activity were similar under the two conditions. These results suggest that prostaglandins modulate the systemic vasoconstrictor effects of angiotensin II.
