Fenoldopam is a medication commonly used in the field of medicine. It is primarily indicated for the treatment of severe hypertension (high blood pressure) in the hospital setting. Its mechanism of action involves selective activation of dopamine receptors, leading to arterial and peripheral vasodilation. The infusion dosing of fenoldopam varies depending on the patient's condition, but it is typically started at a low dose and titrated to achieve the desired blood pressure reduction. Some contraindications for fenoldopam include known hypersensitivity, glaucoma, and use alongside certain monoamine oxidase inhibitors.
