Dược Lực Học : Fenoldopam is an agonist at D1-like dopamine receptors, binds to α2-adrenoceptors, increasing renal blood flow.
Cơ Chế Tác Dụng : A dopamine D1 receptor agonist that is used as an antihypertensive agent. It lowers blood pressure through arteriolar vasodilation. [PubChem] Fenoldopam is a rapid-acting vasodilator. It is an agonist for D1-like dopamine receptors and binds with moderate affinity to α2-adrenoceptors. It has no significant affinity for D2-like receptors, α1 and β-adrenoceptors, 5HT1 and 5HT2 receptors, or muscarinic receptors. Fenoldopam is a racemic mixture with the R-isomer responsible for the biological activity. The R-isomer has approximately 250-fold higher affinity for D1-like receptors than does the S-isomer. In non-clinical studies, fenoldopam had no agonist effect on presynaptic D2-like dopamine receptors, or α or β -adrenoceptors, nor did it affect angiotensin-converting enzyme activity. Fenoldopam may increase norepinephrine plasma concentration.
Dược Động Học :

▧ Metabolism :
Elimination is largely by conjugation, without participation of cytochrome P-450 enzymes. Methylation, glucuronidation, and sulfation are the main routes of conjugation.
▧ Route of Elimination :
Radiolabeled studies show that about 90% of infused fenoldopam is eliminated in urine, 10% in feces. Elimination is largely by conjugation, without participation of cytochrome P-450 enzymes. Only 4% of the administered dose is excreted unchanged.
▧ Half Life :
The elimination half-life is about 5 minutes in mild to moderate hypertensives, with little difference between the R (active) and S isomers.
Độc Tính : The most likely reaction of overdose would be excessive hypotension which should be treated with drug discontinuation and appropriate supportive measures.
Chỉ Định : For the in-hospital, short-term (up to 48 hours) management of severe hypertension when rapid, but quickly reversible, emergency reduction of blood pressure is clinically indicated, including malignant hypertension with deteriorating end-organ function.
