Alfuzosin hydrochloride

6 ADVERSE REACTIONS Most common adverse reactions in clinical studies (incidence ≥2% and at a higher incidence than placebo): dizziness, upper respiratory tract infection, headache, fatigue. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Exelan Pharmaceuticals Inc., at 1-855-295-7455 or www.exelanpharma.com or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 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 alfuzosin hydrochloride 10 mg extended-release tablets. In these trials, 4% of patients taking alfuzosin hydrochloride 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 alfuzosin hydrochloride, 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 Alfuzosin Hydrochloride Treated Patients and More Frequently than with Placebo in 3-Month Placebo-Controlled Clinical Trials Adverse Event Placebo ( n = 678 ) Alfuzosin HCl ( n = 473 ) Dizziness Upper respiratory tract infection Headache Fatigue 19 (2.8%) 4 (0.6%) 12 (1.8%) 12 (1.8%) 27 (5.7%) 14 (3.0%) 14 (3.0%) 13 (2.7%) The following adverse reactions, reported by between 1% and 2% of patients receiving alfuzosin hydrochloride 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 ) Alfuzosin HCl ( n = 473 ) Dizziness Hypotension or postural hypotension Syncope 19 (2.8%) 0 0 27 (5.7%) 2 (0.4%) 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 alfuzosin hydrochloride 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 alfuzosin hydrochloride 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 alfuzosin hydrochloride patients. 6.2 Post-marketing Experience The following adverse reactions have been identified during post approval use of alfuzosin hydrochloride. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. General disorders: edema Cardiac disorders: tachycardia, chest pain, angina pectoris in patients with pre-existing coronary artery disease, atrial fibrillation Gastrointestinal disorders: diarrhea Hepatobiliary disorders: hepatocellular and cholestatic liver injury (including cases with jaundice leading to drug discontinuation) Respiratory system disorders: rhinitis Reproductive system disorders: priapism Skin and subcutaneous tissue disorders: rash, pruritis, urticaria, angioedema Vascular disorders: flushing Blood and lymphatic system disorders: thrombocytopenia During cataract surgery, a variant of small pupil syndrome known as Intraoperative Floppy Iris Syndrome (IFIS) has been reported in some patients on or previously treated with alpha adrenergic antagonists [see Warnings and Precautions ( 5.6 )] .

4 CONTRAINDICATIONS Alfuzosin hydrochloride is contraindicated for use: in patients with moderate or severe hepatic impairment (Childs-Pugh categories B and C), since alfuzosin blood levels are increased in these patients [see Use in Specific Populations ( 8.7 ) and Clinical Pharmacology ( 12.3 )] . with potent CYP3A4 inhibitors such as ketoconazole, itraconazole, and ritonavir, since alfuzosin blood levels are increased [see Drug Interactions ( 7.1 ) and Clinical Pharmacology ( 12.3 )] . in patients with known hypersensitivity, such as urticaria and angioedema, to alfuzosin hydrochloride or any component of alfuzosin hydrochloride tablets [see Adverse Reactions ( 6.2 )] . Moderate or severe hepatic impairment ( 4 , 8.7 , 12.3 ) Co-administration with potent CYP3A4 inhibitors (e.g.ketoconazole, itraconazole, ritonavir) ( 4 , 5.4 , 7.1 , 12.3 ) Known hypersensitivity (e.g., urticaria or angioedema) to alfuzosin or any of the ingredients ( 4 , 6.2 )

11 DESCRIPTION Each alfuzosin hydrochloride extended-release tablet contains 10 mg alfuzosin hydrochloride as the active ingredient.

It is freely soluble in water, sparingly soluble in alcohol, and practically insoluble in dichloromethane. Alfuzosin hydrochloride, USP is (R,S)-N-[3-[(4-amino-6,7-dimethoxy-2-quinazolinyl) methylamino] propyl] tetrahydro-2-furancarboxamide hydrochloride. The empirical formula of alfuzosin hydrochloride is C 19 H 27 N 5 O 4 •HCl. The molecular weight of alfuzosin hydrochloride is 425.9. Its structural formula is: The tablet also contains the following inactive ingredients: microcrystalline cellulose (NF), guar gum (NF), hydroxypropyl methyl cellulose (USP), silicon dioxide (NF) and magnesium stearate (NF). dia1

2 DOSAGE AND ADMINISTRATION The recommended dosage is one 10 mg alfuzosin hydrochloride extended-release tablet once daily. The extent of absorption of alfuzosin is 50% lower under fasting conditions. Therefore, alfuzosin hydrochloride should be taken with food and with the same meal each day. The tablets should not be chewed or crushed. 10 mg once daily with food and with the same meal each day ( 2 ) Tablets should not be chewed or crushed ( 2 , 12.3 )

1 INDICATIONS AND USAGE Alfuzosin hydrochloride is indicated for the treatment of signs and symptoms of benign prostatic hyperplasia. Alfuzosin hydrochloride is an alpha adrenergic antagonist, indicated for treatment of signs and symptoms of benign prostatic hyperplasia. ( 1 ) Important Limitations of Use: Alfuzosin hydrochloride is not indicated for the treatment of hypertension. ( 1.1 ) Alfuzosin hydrochloride is not indicated for use in the pediatric population. ( 1.1 , 8.4 , 12.3 ) 1.1 Important Limitations of Use Alfuzosin hydrochloride is not indicated for the treatment of hypertension. Alfuzosin hydrochloride is not indicated for use in the pediatric population.

10 OVERDOSAGE Should overdose of alfuzosin hydrochloride lead to hypotension, support of the cardiovascular system is of first importance. Restoration of blood pressure and normalization of heart rate may be accomplished by keeping the patient in the supine position. If this measure is inadequate, then the administration of intravenous fluids should be considered. If necessary, vasopressors should then be used, and the renal function should be monitored and supported as needed. Alfuzosin is 82% to 90% protein bound; therefore, dialysis may not be of benefit.

7 DRUG INTERACTIONS Concomitant use of PDE5 inhibitors with alpha adrenergic antagonists, including alfuzosin hydrochloride, can potentially cause symptomatic hypotension ( 5.4 , 7.4 ) 7.1 CYP3A4 inhibitors Alfuzosin hydrochloride 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 )] . 7.2 Alpha adrenergic antagonists The pharmacokinetic and pharmacodynamic interactions between alfuzosin hydrochloride and other alpha adrenergic antagonists have not been determined. However, interactions may be expected, and alfuzosin hydrochloride should not be used in combination with other alpha adrenergic antagonists [see Warnings and Precautions ( 5.4 )] . 7.3 Antihypertensive Medication and Nitrates There may be an increased risk of hypotension/postural hypotension and syncope when taking alfuzosin hydrochloride concomitantly with anti-hypertensive medication and nitrates [see Warnings and Precautions ( 5.1 )] . 7.4 PDE5 Inhibitors Caution is advised when alpha adrenergic antagonists, including alfuzosin hydrochloride, are coadministered with PDE 5 inhibitors. Alpha adrenergic antagonists and PDE 5 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 )] .

12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Alfuzosin is a selective antagonist of post-synaptic alpha1-adrenoreceptors, which are located in the prostate, bladder base, bladder neck, prostatic capsule, and prostatic urethra. 12.2 Pharmacodynamics Alfuzosin exhibits selectivity for alpha adrenergic receptors in the lower urinary tract. Blockade of these adrenoreceptors can cause smooth muscle in the bladder neck and prostate to relax, resulting in an improvement in urine flow and a reduction in symptoms of BPH. Cardiac Electrophysiology The effect of 10 mg and 40 mg alfuzosin on QT interval was evaluated in a double-blind, randomized, placebo and active-controlled (moxifloxacin 400 mg), 4-way crossover single dose study in 45 healthy white male subjects aged 19 to 45 years. The QT interval was measured at the time of peak alfuzosin plasma concentrations. The 40 mg dose of alfuzosin was chosen because this dose achieves higher blood levels than those achieved with the co-administration of alfuzosin hydrochloride and ketoconazole 400 mg. Table 3 summarizes the effect on uncorrected QT and mean corrected QT interval (QTc) with different methods of correction (Fridericia, population specific and subject-specific correction methods) at the time of peak alfuzosin plasma concentrations. No single one of these correction methodologies is known to be more valid. The mean change of heart rate associated with a 10 mg dose of alfuzosin in this study was 5.2 beats/minute and 5.8 beats/minute with 40 mg alfuzosin. The change in heart rate with moxifloxacin was 2.8 beats/minute. Table 3. Mean QT and QTc changes in msec (95% CI) from baseline at T max (relative to placebo) with different methodologies to correct for effect of heart rate. Drug/Dose QT Fridericia method Population- specific method Subject- specific method Alfuzosin 10 mg -5.8 (-10.2, -1.4) 4.9 (0.9, 8.8) 1.8 (-1.4, 5.0) 1.8 (-1.3, 5.0) Alfuzosin 40 mg -4.2 (-8.5, 0.2) 7.7 (1.9, 13.5) 4.2 (-0.6, 9.0) 4.3 (-0.5, 9.2) Moxifloxacin Active control 400 mg 6.9 (2.3, 11.5) 12.7 (8.6, 16.8) 11 (7.0, 15.0) 11.1 (7.2, 15.0) The QT effect appeared greater for 40 mg compared to 10 mg alfuzosin. The effect of the highest alfuzosin dose (four times the therapeutic dose) studied did not appear as large as that of the active control moxifloxacin at its therapeutic dose. This study, however, was not designed to make direct statistical comparisons between the drugs or the dose levels. There has been no signal of Torsade de Pointes in the extensive post-marketing experience with alfuzosin outside the United States. A separate post-marketing QT study evaluated the effect of the co-administration of 10 mg alfuzosin with a drug of similar QT effect size. In this study, the mean placebo-subtracted QTcF increase of alfuzosin 10 mg alone was 1.9 msec (upperbound 95% Cl, 5.5 msec). The concomitant administration of the two drugs showed an increased QT effect when compared with either drug alone. This QTcF increase [5.9 msec (UB 95% Cl, 9.4 msec)] was not more than additive. Although this study was not designed to make direct statistical comparisons between drugs, the QT increase with both drugs given together appeared to be lower than the QTcF increase seen with the positive control moxifloxacin 400 mg [10.2 msec (UB 95% Cl, 13.8 msec)]. The clinical impact of these QTc changes is unknown. 12.3 Pharmacokinetics The pharmacokinetics of alfuzosin hydrochloride have been evaluated in adult healthy male volunteers after single and/or multiple administration with daily doses ranging from 7.5 mg to 30 mg, and in patients with BPH at doses from 7.5 mg to 15 mg. Absorption The absolute bioavailability of alfuzosin hydrochloride 10 mg tablets under fed conditions is 49%. Following multiple dosing of 10 mg alfuzosin hydrochloride under fed conditions, the time to maximum concentration is 8 hours. C max and AUC 0-24 are 13.6 (SD = 5.6) ng/mL and 194 (SD = 75) ng•h/mL, respectively. Alfuzosin hydrochloride exhibits linear kinetics following single and multiple dosing up to 30 mg. Steady-state plasma levels are reached with the second dose of alfuzosin hydrochloride administration. Steady-state alfuzosin plasma concentrations are 1.2- to 1.6-fold higher than those observed after a single administration. Effect of Food As illustrated in Figure 1, the extent of absorption is 50% lower under fasting conditions. Therefore, alfuzosin hydrochloride should be taken with food and with the same meal each day [see Dosage and Administration ( 2 )] . Figure 1 – Mean (SEM) Alfuzosin Plasma Concentration-Time Profiles after a Single Administration of Alfuzosin Hydrochloride 10 mg tablets to 8 Healthy Middle-Aged Male Volunteers in Fed and Fasted States Distribution The volume of distribution following intravenous administration in healthy male middle-aged volunteers was 3.2 L/kg. Results of in vitro studies indicate that alfuzosin is moderately bound to human plasma proteins (82% to 90%), with linear binding over a wide concentration range (5 to 5,000 ng/mL). Metabolism Alfuzosin undergoes extensive metabolism by the liver, with only 11% of the administered dose excreted unchanged in the urine. Alfuzosin is metabolized by three metabolic pathways: oxidation, O-demethylation, and N-dealkylation. The metabolites are not pharmacologically active. CYP3A4 is the principal hepatic enzyme isoform involved in its metabolism. Excretion Following oral administration of 14 C-labeled alfuzosin solution, the recovery of radioactivity after 7 days (expressed as a percentage of the administered dose) was 69% in feces and 24% in urine. Following oral administration of alfuzosin hydrochloride 10 mg tablets, the apparent elimination half-life is 10 hours. Specific Populations Geriatric Use: In a pharmacokinetic assessment during phase 3 clinical studies in patients with BPH, there was no relationship between peak plasma concentrations of alfuzosin and age. However, trough levels were positively correlated with age. The concentrations in subjects ≥75 years of age were approximately 35% greater than in those below 65 years of age. Renal Impairment: The Pharmacokinetic profiles of alfuzosin hydrochloride 10 mg tablets in subjects with normal renal function (CLCR>80 mL/min), mild impairment (CLCR 60 to 80 mL/min), moderate impairment (CLCR 30 to 59 mL/min), and severe impairment (CLCR <30 mL/min) were compared. These clearances were calculated by the Cockcroft-Gault formula. Relative to subjects with normal renal function, the mean C max and AUC values were increased by approximately 50% in patients with mild, moderate, or severe renal impairment [see Warnings and Precautions ( 5.2 ) and Use in Specific Populations ( 8.6 )] . Hepatic Impairment: The pharmacokinetics of alfuzosin hydrochloride have not been studied in patients with mild hepatic impairment. In patients with moderate or severe hepatic insufficiency (Child-Pugh categories B and C), the plasma apparent clearance (CL/F) was reduced to approximately one-third to one-fourth that observed in healthy subjects. This reduction in clearance results in three to four-fold higher plasma concentrations of alfuzosin in these patients compared to healthy subjects. Therefore, alfuzosin hydrochloride is contraindicated in patients with moderate to severe hepatic impairment [see Contraindications ( 4 ), Warnings and Precautions ( 5.3 ) and Use in Specific Populations ( 8.7 )] . Pediatric Use: Alfuzosin hydrochloride tablets are not indicated for use in the pediatric population [see Indications and Usage ( 1.1 ) and Use in Specific Populations ( 8.4 )] . Drug-Drug Interactions Metabolic Interactions CYP3A4 is the principal hepatic enzyme isoform involved in the metabolism of alfuzosin. Potent CYP3A4 Inhibitors Repeated oral administration of 400 mg/day of ketoconazole, a potent inhibitor of CYP3A4, increased alfuzosin Cmax by 2.3-fold and AUClast by 3.2-fold, following a single 10 mg dose of alfuzosin. In another study, repeated oral administration of a lower (200 mg/day) dose of ketoconazole increased alfuzosin Cmax by 2.1 -fold and AUClast by 2.5-fold, following a single 10 mg dose of alfuzosin. Therefore, alfuzosin hydrochloride is contraindicated for co-administration with potent inhibitors of CYP3A4 (e.g., ketoconazole, itraconazole, or ritonavir) because of increased alfuzosin exposure[ see Contraindications ( 4 ), Warnings and Precautions ( 5.4 ) and Drug Interactions ( 7.1 )] . Moderate CYP3A4 Inhibitors Diltiazem: Repeated co-administration of 240 mg/day of diltiazem, a moderately-potent inhibitor of CYP3A4, with 7.5 mg/day (2.5 mg three times daily) alfuzosin (equivalent to the exposure with alfuzosin hydrochloride) increased the C max and AUC 0-24 of alfuzosin 1.5- and 1.3-fold, respectively. Alfuzosin increased the C max and AUC 0-12 of diltiazem 1.4-fold. Although no changes in blood pressure were observed in this study, diltiazem is an antihypertensive medication and the combination of alfuzosin hydrochloride and antihypertensive medications has the potential to cause hypotension in some patients [see Warnings and Precautions ( 5.1 )] . In human liver microsomes, at concentrations that are achieved at the therapeutic dose, alfuzosin did not inhibit CYP1A2, 2A6, 2C9, 2C19, 2D6 or 3A4 isoenzymes. In primary culture of human hepatocytes, alfuzosin did not induce CYP1A, 2A6 or 3A4 isoenzymes. Other Interactions Warfarin: Multiple dose administration of an immediate release tablet formulation of alfuzosin 5 mg twice daily for six days to six healthy male volunteers did not affect the pharmacological response to a single 25 mg oral dose of warfarin. Digoxin: Repeated co-administration of alfuzosin hydrochloride 10 mg tablets and digoxin 0.25 mg/day for 7 days did not influence the steady-state pharmacokinetics of either drug. Cimetidine: Repeated administration of 1 g/day cimetidine increased both alfuzosin C max and AUC values by 20%. Atenolol: Single administration of 100 mg atenolol with a single dose of 2.5 mg of an immediate release alfuzosin tablet in eight healthy young male volunteers increased alfuzosin C max and AUC values by 28% and 21%, respectively. Alfuzosin increased atenolol C max and AUC values by 26% and 14%, respectively. In this study, the combination of alfuzosin with atenolol caused significant reductions in mean blood pressure and in mean heart rate. [see Warnings and Precautions ( 5.1 )] . Hydrochlorothiazide: Single administration of 25 mg hydrochlorothiazide did not modify the pharmacokinetic parameters of alfuzosin. There was no evidence of pharmacodynamic interaction between alfuzosin and hydrochlorothiazide in the 8 patients in this study. alf4

The highest dose tested in female mice may not have constituted a maximally tolerated dose. Likewise, there was no evidence of a drug-related increase in the incidence of tumors in rats following dietary administration of 100 mg/kg/day alfuzosin for 104 weeks (53 and 37 times the MRHD in females and males, respectively). Alfuzosin showed no evidence of mutagenic effect in the Ames and mouse lymphoma assays, and was free of any clastogenic effects in the Chinese hamster ovary cell and in vivo mouse micronucleus assays. Alfuzosin treatment did not induce DNA repair in a human cell line. There was no evidence of reproductive organ toxicity when male rats were administered oral doses of several hundred times (250 mg/kg/day for 26 weeks) the MRHD of alfuzosin. No impairment of fertility was observed following oral (gavage) administration to male rats at doses of up to 125 mg/kg/day for 70 days. Estrous cycling was inhibited in rats and dogs at approximately 12 and 18 times the MRHD respectively (doses of 25 mg/kg and 20 mg/kg, respectively), but did not result in impaired fertility in female rats.

14 CLINICAL STUDIES Three randomized placebo-controlled, double-blind, parallel-arm, 12-week trials were conducted with the 10 mg daily dose of alfuzosin. In these three trials, 1,608 patients [mean age 64.2 years, range 49-92 years; Caucasian (96.1%), Black (1.6%), Asian (1.1%), other (1.2%)] were randomized and 473 patients received alfuzosin hydrochloride 10 mg daily. Table 4 provides the results of the three trials that evaluated the 10 mg dose. There were two primary efficacy variables in these three studies. The International Prostate Symptom Score (IPSS, or AUA Symptom Score) consists of seven questions that assess the severity of both irritative (frequency, urgency, nocturia) and obstructive (incomplete emptying, stopping and starting, weak stream, and pushing or straining) symptoms, with possible scores ranging from 0 to 35 with higher numerical scores on the IPSS total symptom score representing greater severity of symptoms. The second efficacy variable was peak urinary flow rate. The peak flow rate was measured just prior to the next dose in study 2 and on average at 16 hours post dosing in trials 1 and 3. There was a statistically significant reduction from baseline to last assessment (Week 12) in the IPSS total symptom score versus placebo in all three studies, indicating a reduction in symptom severity (Table 5 and Figures 2, 3, and 4).

8.5 Geriatric Use Of the total number of subjects in clinical studies of alfuzosin hydrochloride, 48% were 65 years of age and over, whereas 11% were 75 and over. No overall differences in safety or effectiveness were observed between these subjects and younger subjects, but greater sensitivity of some older individuals cannot be ruled out [see Clinical Pharmacology ( 12.3 )] .

8.4 Pediatric Use Alfuzosin hydrochloride extended release tablets are not indicated for use in the pediatric population. Additional information regarding a clinical study in which efficacy was not demonstrated in pediatric patients ages 2 to 16 years is approved for Sanofi-Aventis U.S. LLC’s alfuzosin hydrochloride extended-release tablets. However, due to Sanofi-Aventis U.S. LLC’s marketing exclusivity rights, this drug is not labeled with that pediatric information.

8.1 Pregnancy Pregnancy Category B. Alfuzosin hydrochloride is not indicated for use in women, and there are no studies of alfuzosin in pregnant women. Alfuzosin was not teratogenic, embryotoxic or fetotoxic in rats at plasma exposure levels (based on AUC of unbound drug) up to 1200 times (maternal oral dose of 250 mg/kg/day) the maximum recommended human dose (MRHD) of 10 mg. In rabbits administered up to 3 times the MRHD (based on body surface area) (maternal oral dose of 100 mg/kg/day) no embryofetal toxicity or teratogenicity was observed. Gestation was slightly prolonged in rats at exposure levels (based on AUC of unbound drug) approximately 12 times (greater than 5 mg/kg/day oral maternal dose) the MRHD, but difficulties with parturition were not observed.

No overall differences in safety or effectiveness were observed between these subjects and younger subjects, but greater sensitivity of some older individuals cannot be ruled out [see Clinical Pharmacology ( 12.3 )] . 8.6 Renal impairment Systemic exposure was increased by approximately 50% in pharmacokinetic studies of patients with mild, moderate, and severe renal impairment [see Clinical Pharmacology ( 12.3 )]. In phase 3 studies, the safety profile of patients with mild (n=172) or moderate (n=56) renal impairment was similar to the patients with normal renal function in those studies. Safety data are available in only a limited number of patients (n=6) with creatinine clearance below 30 mL/min; therefore, caution should be exercised when alfuzosin hydrochloride is administered in patients with severe renal impairment [see Warnings and Precautions (5.2) ] . 8.7 Hepatic impairment The pharmacokinetics of alfuzosin hydrochloride have not been studied in patients with mild hepatic impairment. Alfuzosin hydrochloride is contraindicated for use in patients with moderate or severe hepatic impairment [see Contraindications ( 4 ), Warnings and Precautions ( 5.3 ) and Clinical Pharmacology ( 12.3 )] .
