Fenoldopam (Corlopam), a new dopaminergic agent in clinical development by SmithKline Beecham Pharmaceuticals, is a dopamine-1 (DA1) agonist at post-synaptic dopamine receptors. Preclinical and clinical studies have demonstrated that it is a potent renal vasodilator as well as a peripheral vasodilator. In both normal volunteers and hypertensive patients intravenous fenoldopam causes dose-related decreases in blood pressure and important increases in renal hemodynamics and function including increased renal blood flow, diuresis and natriuresis. Fenoldopam does not alter glomerular filtration. Intravenous fenoldopam has been demonstrated to be efficacious in severe hypertensive patients in several multicenter, multinational trials. In severe hypertension efficacy trials fenoldopam was judged to be as effective as sodium nitroprusside and to produce less serious side effects. In patients with moderate to severe heart failure, fenoldopam has been demonstrated to produce dose-related acute increases in cardiac output, stroke volume and work index, decreased systemic vascular resistance but no important changes in pulmonary wedge pressure or right atrial pressure. In CHF patients fenoldopam has been demonstrated to be as efficacious as sodium nitroprusside. Fenoldopam, as a specific (DA1) agonist resulting in decreased peripheral and renal vascular resistance, diuresis, natriuresis and increases in cardiac hemodynamics on intravenous administration, appears to be an efficacious agent which offers a reasonable alternative in the treatment of severe hypertension and acute congestive heart failure.
