Drug Interactions

CYP3A4 Inhibitors

Uroxatral is contraindicated for use with potent CYP3A4 inhibitors such as ketoconazole, itraconazole, or ritonavir, since alfuzosin blood levels are increased [see Contraindications (4), Warnings and Precautions (5.4) and Clinical Pharmacology (12.3)].

Alpha Adrenergic Antagonists

The pharmacokinetic and pharmacodynamic interactions between Uroxatral and other alpha adrenergic antagonists have not been determined. However, interactions may be expected, and Uroxatral should not be used in combination with other alpha adrenergic antagonists [see Warnings and Precautions (5.4)].

Antihypertensive Medication and Nitrates

There may be an increased risk of hypotension/postural hypotension and syncope when taking Uroxatral concomitantly with anti-hypertensive medication and nitrates [see Warnings and Precautions (5.1)].

PDE5 Inhibitors

Caution is advised when alpha adrenergic antagonists, including Uroxatral, are co-administered with PDE5 inhibitors. Alpha adrenergic antagonists and PDE5 inhibitors are both vasodilators that can lower blood pressure. Concomitant use of these two drug classes can potentially cause symptomatic hypotension [see Warnings and Precautions (5.4)].
