Assessment of intravenous fenoldopam mesylate in the management of severe systemic hypertension.
To evaluate the acute BP response to iv fenoldopam mesylate (FNP), 14 patients with severe hypertension (diastolic BP 120 to 170 mm Hg) were studied in an open-label trial. Initial infusion rate of FNP was 0.1 microgram/kg.min. Titration to diastolic BP goal (95 to 110 mm Hg) was followed by a constant infusion phase (greater than or equal to 6 h), a detitration phase (2 h), and a postinfusion phase. FNP reduced BP by 27/29 mm Hg (p less than .001) with no significant effect on heart rate. Maintenance of the BP effect was noted through the 6 h of constant rate infusion. Mild, transient vasodilating-associated adverse effects were noted with FNP. We conclude that FNP is an effective, well-tolerated iv antihypertensive agent for acute BP reduction in a severely hypertensive population.
