drug details
nameFenoldopam
ClassificationPeripheral Dopamine-1 Agonist
Pharmacokinetics
absorptionRapidly absorbed after intravenous administration. Peak plasma concentrations are reached within 5 minutes.
distributionDistributed throughout the body, with significant metabolism in the liver.
metabolismMetabolized primarily by the liver into inactive metabolites. Renal excretion is minimal.
eliminationElimination half-life is short, typically around 10 minutes, allowing for precise blood pressure control.
suggested dosage
noteDosage must be individualized based on patient's blood pressure response. Fenoldopam is typically administered intravenously.
rangeStarting dose range is typically 0.01-0.2 mcg/kg/min, titrated to effect.
special considerationsClose monitoring of blood pressure is essential and frequent adjustments to dosage may be needed.
weight adjusted dosageFenoldopam dosage is weight-adjusted and must be calculated meticulously by medical professionals, taking into account individual patient physiology.
exampleFor a 70kg patient, the starting dosage would range from 0.07-1.4 mcg/min (approximately 0.01-0.2 mcg/kg/min).
indicationsFenoldopam is primarily used for the short-term management of severe hypertension requiring rapid blood pressure reduction, e.g., hypertensive emergencies.
Safety in pregnancyLimited data are available. The drug should be used only when clearly needed and potential risks to the mother and fetus are carefully considered and weighed. This must be discussed by the treating physician.
Safety in breastfeedingFenoldopam is present in breast milk. The potential risks and benefits to the infant need to be evaluated carefully before prescribing. This should be discussed with the prescribing doctor.

contraindications
1Severe aortic stenosis
2Hypersensitivity to fenoldopam or its components.
3Significant coronary artery disease, especially uncompensated heart failure
interactions
1Concomitant use with other antihypertensive medications may potentiate blood pressure reduction, and thus require careful monitoring and dosage adjustment.
2Use with drugs affecting cardiac output (e.g., certain beta-blockers) should be approached with caution.
warnings and precautions
1Rapid decreases in blood pressure can precipitate acute myocardial ischemia or stroke. Continuous blood pressure monitoring is essential.
2Closely monitor patients for signs of hypotension, especially during the initial period of therapy
3Patients with pre-existing cardiac disease may be at higher risk. Individualize treatment.
4Careful assessment of the need for and appropriateness of the drug is important prior to administration and the potential for cardiovascular events should be monitored during administration.
additional informations
1Fenoldopam is a potent vasodilator, primarily acting on vascular smooth muscles. It has a very short duration of action
2Rapid IV administration should be avoided to minimize the risk of adverse effects.
3Storage: Store in a cool, dry place, away from direct sunlight.
