UROXATRAL- alfuzosin hydrochloride tablet, extended release
sanofi-aventis U.S. LLC


UROXATRAL is indicated for the treatment of signs and symptoms of benign prostatic hyperplasia.

1.1 Important Limitations of Use

UROXATRAL is not indicated for the treatment of hypertension.

UROXATRAL is not indicated for use in the pediatric population.


The recommended dosage is one 10 mg UROXATRAL (alfuzosin HCl) extended-release tablet once daily. The extent of absorption of alfuzosin is 50% lower under fasting conditions. Therefore, Uroxatral should be taken with food and with the same meal each day. The tablets should not be chewed or crushed.


UROXATRAL (alfuzosin HCl) extended-release tablet 10 mg is available as a round, three-layer tablet: one white layer between two yellow layers, debossed with X10.


UROXATRAL is contraindicated for use:


5.1 Postural Hypotension

Postural hypotension with or without symptoms (e.g., dizziness) may develop within a few hours following administration of UROXATRAL. As with other alpha adrenergic antagonists, there is a potential for syncope. Patients should be warned of the possible occurrence of such events and should avoid situations where injury could result should syncope occur. There may be an increased risk of hypotension/postural hypotension and syncope when taking UROXATRAL concomitantly with anti-hypertensive medication and nitrates. Care should be taken when UROXATRAL is administered to patients with symptomatic hypotension or patients who have had a hypotensive response to other medications.

5.2 Patients with Renal Impairment

Caution should be exercised when UROXATRAL is administered in patients with severe renal impairment (creatinine clearance < 30 mL/min) [see Use in Specific Populations (8.6) and Clinical Pharmacology (12.3)].

5.3 Patients with Hepatic Impairment

UROXATRAL is contraindicated for use in patients with moderate or severe hepatic impairment [see Contraindications (4), Use in Specific Populations (8.7) and Clinical Pharmacology (12.3)]. Although the pharmacokinetics of UROXATRAL have not been studied in patients with mild hepatic impairment, caution should be exercised when UROXATRAL is administered to such patients [see Use in Specific Populations (8.7) and Clinical Pharmacology (12.3)].

5.4 Drug-Drug Interactions

Potent CYP3A4 Inhibitors: UROXATRAL is contraindicated for use with potent CYP3A4 inhibitors (e.g. ketoconazole, itraconazole, ritonavir) since alfuzosin blood levels are increased [see Contraindications (4), Drug Interactions (7.1) and Clinical Pharmacology (12.3)].

Other alpha adrenergic antagonists: UROXATRAL is an alpha adrenergic antagonist and should not be used in combination with other alpha adrenergic antagonist [see Drug Interactions (7.2)].

Phosphodiesterase-5 (PDE5) Inhibitors: PDE5-inhibitors are also vasodilators. Caution is advised for concomitant use of PDE5-inhibitors and UROXATRAL, as this combination can potentially cause symptomatic hypotension [see Drug Interactions (7.4)].

5.5 Prostatic Carcinoma

Carcinoma of the prostate and benign prostatic hyperplasia (BPH) cause many of the same symptoms. These two diseases frequently coexist. Therefore, patients thought to have BPH should be examined to rule out the presence of carcinoma of the prostate prior to starting treatment with UROXATRAL.

5.6 Intraoperative Floppy Iris Syndrome (IFIS)

IFIS has been observed during cataract surgery in some patients on or previously treated with alpha adrenergic antagonists. This variant of small pupil syndrome is characterized by the combination of a flaccid iris that billows in response to intraoperative irrigation currents, progressive intraoperative miosis despite preoperative dilation with standard mydriatic drugs, and potential prolapse of the iris toward the phacoemulsification incisions. The patient’s ophthalmologist should be prepared for possible modifications to their surgical technique, such as the utilization of iris hooks, iris dilator rings, or viscoelastic substances.

There does not appear to be a benefit of stopping alpha adrenergic antagonist therapy prior to cataract surgery.

5.7 Priapism

Rarely (probably less than 1 in 50,000), alfuzosin, like other alpha adrenergic antagonists, has been associated with priapism (persistent painful penile erection unrelated to sexual activity). Because this condition can lead to permanent impotence if not properly treated, patients should be advised about the seriousness of the condition [see Adverse Reactions (6.2) and Patient Counseling Information [17.3]).

5.8 Coronary Insufficiency

If symptoms of angina pectoris should appear or worsen, UROXATRAL should be discontinued.

5.9 Patients with Congenital or Acquired QT Prolongation

Use with caution in patients with acquired or congenital QT prolongation or who are taking medications that prolong the QT interval [see Clinical Pharmacology (12.2)].


6.1 Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.

The incidence of adverse reactions has been ascertained from 3 placebo-controlled clinical trials involving 1,608 men where daily doses of 10 and 15 mg alfuzosin were evaluated. In these 3 trials, 473 men received UROXATRAL (alfuzosin HCl) 10 mg extended-release tablets. In these trials, 4% of patients taking UROXATRAL (alfuzosin HCl) 10 mg extended-release tablets withdrew from the trial due to adverse reactions, compared with 3% in the placebo group.

Table 1 summarizes adverse reactions that occurred in ≥2% of patients receiving UROXATRAL, and at a higher incidence than that of the placebo group. In general, the adverse reactions seen in long-term use were similar in type and frequency to the events described below for the 3-month trials.

Table 1 — Adverse Reactions Occurring in ≥2% of UROXATRAL-Treated Patients and More Frequently than with Placebo in 3-Month Placebo-Controlled Clinical Trials
Adverse Reaction Placebo(n=678) UROXATRAL(n=473)
Dizziness 19 (2.8%) 27 (5.7%)
Upper respiratory tract infection 4 (0.6%) 14 (3.0%)
Headache 12 (1.8%) 14 (3.0%)
Fatigue 12 (1.8%) 13 (2.7%)

The following adverse reactions, reported by between 1% and 2% of patients receiving UROXATRAL and occurring more frequently than with placebo, are listed alphabetically by body system and by decreasing frequency within body system:

Body as a whole: pain

Gastrointestinal system: abdominal pain, dyspepsia, constipation, nausea

Reproductive system: impotence

Respiratory system: bronchitis, sinusitis, pharyngitis

Signs and Symptoms of Orthostasis in Clinical Trials: The adverse reactions related to orthostasis that occurred in the double-blind phase 3 trials with alfuzosin 10 mg are summarized in Table 2. Approximately 20% to 30% of patients in these trials were taking antihypertensive medication.

Table 2— Number (%) of Patients with Symptoms Possibly Associated with Orthostasis in 3-Month Placebo-Controlled Clinical Trials
Symptoms Placebo(n=678) UROXATRAL(n=473)
Dizziness 19 (2.8%) 27 (5.7%)
Hypotension or postural hypotension 0 2 (0.4%)
Syncope 0 1 (0.2%)

Testing for blood pressure changes or orthostatic hypotension was conducted in three controlled studies. Decreased systolic blood pressure (≤90 mm Hg, with a decrease ≥20 mm Hg from baseline) was observed in none of the 674 placebo patients and 1 (0.2%) of the 469 UROXATRAL patients. Decreased diastolic blood pressure (≤50 mm Hg, with a decrease ≥15 mm Hg from baseline) was observed in 3 (0.4%) of the placebo patients and in 4 (0.9%) of the UROXATRAL patients. A positive orthostatic test (decrease in systolic blood pressure of ≥20 mm Hg upon standing from the supine position) was seen in 52 (7.7%) of placebo patients and in 31 (6.6%) of the UROXATRAL patients.
