🩺 Clinical
Alfuzosin is used to treat benign prostatic hyperplasia (BPH; enlarged prostate that can cause difficulty urinating, painful urination or increased urinary frequency or urgency). Alfuzosin is in a class of medications called alpha blockers. It works by relaxing the muscles in the prostate and bladder so that urine can flow more easily.

- Yes, this one really does matter. Taking alfuzosin without food reduces the amount your body absorbs by about half, which means it won't work as well. Try to take it with the same...

⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Postural hypotension/syncope: Care should be taken in patients with symptomatic hypotension or who have had a hypotensive response to other medications or are concomitantly treated with antihypertensive medication or nitrates ( 5.1 ) Use with caution in patients with severe renal impairment (creatinine clearance <30 mL/min) ( 5.2 , 8.6 , 12.3 ) Use with caution in patients with mild hepatic impairment ( 5.3 , 8.7 , 12.3 ) Should not be used in combination with other alpha adrenergic antagonists ( 5.4 , 7.2 ) Prostate carcinoma should be ruled out prior to treatment ( 5.5 ) Intraoperative Floppy Iris Syndrome (IFIS) during cataract surgery may require modifications to the surgical technique ( 5.6 ) Discontinue alfuzosin hydrochloride if symptoms of angina pectoris appear or worsen ( 5.8 ) Use with caution in patients with a history of QT prolongation or who are taking medications which prolong the QT interval ( 5.9 , 12.2 )
5.1Postural Hypotension Postural hypotension with or without symptoms (e.g., dizziness) may develop within a few hours following administration of alfuzosin hydrochloride. 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 alfuzosin hydrochloride concomitantly with anti-hypertensive medication and nitrates. Care should be taken when alfuzosin hydrochloride is administered to patients with symptomatic hypotension or patients who have had a hypotensive response to other medications.
5.2Patients with Renal Impairment Caution should be exercised when alfuzosin hydrochloride 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 )] .
5.3Patients with Hepatic Impairment Alfuzosin hydrochloride 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 alfuzosin hydrochloride have not been studied in patients with mild hepatic impairment, caution should be exercised when alfuzosin hydrochloride is administered to such patients [see Use in Specific Populations ( 8.7 ) and Clinical Pharmacology ( 12.3 )] .
5.4Drug-Drug Interactions Potent CYP3A4 Inhibitors: Alfuzosin hydrochloride 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: Alfuzosin hydrochloride 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 alfuzosin hydrochloride, as this combination can potentially cause symptomatic hypotension [see Drug Interactions ( 7.4 )].
5.5Prostatic 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 alfuzosin hydrochloride.
5.6Intraoperative 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 p…
🤒 Adverse Reactions ▾
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 1-866-604-3268 or www.exelanpharma.com or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch .
6.1Clinical 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.
6.2Post-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…

👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS
8.1Pregnancy Risk Summary Alfuzosin hydrochloride extended-release tablets is not indicated for use in women. There are no adequate data on the developmental risk associated with use of Alfuzosin hydrochloride extended-release tablets in pregnant women. Based on findings from animal studies, alfuzosin administered during the period of organogenesis was not teratogenic, embryotoxic or fetotoxic at up to 1200 times the MRHD of 10 mg via AUC in rats and 3 times in rabbits, via body surface area.
In the U.S. general population, the estimated background risk of major birth defects and of miscarriage in clinically recognized pregnancy is 2-4% and 15-20%, respectively. Data Animal data 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.
8.2Lactation Risk Summary Alfuzosin hydrochloride extended-release tablets is not indicated for use in women. There are no data on the presence of Alfuzosin hydrochloride extended-release tablets in human milk, the effect on the breastfed child, or effect on milk production.
8.4Pediatric Use Alfuzosin hydrochloride extended-release tablets are not indicated for use in the pediatric population. Efficacy of alfuzosin hydrochloride was not demonstrated in a randomized, double-blind, placebo-controlled, efficacy and safety trial conducted in 172 patients ages 2 to 16 years with elevated detrusor leak point pressure (LPP≥40 cm H2O) of neurologic origin treated with alfuzosin hydrochloride using pediatric formulations. The trial included a 12-week efficacy phase followed by a 40-week safety extension period.
No statistically significant difference in the proportion of patients achieving a detrusor leak point pressure of <40 cmH20 was observed between the alfuzosin and placebo groups. During the placebo-controlled trial, the adverse reactions reported in ≥2% of patients treated with alfuzosin and at a higher incidence than in the placebo group were: pyrexia, headache, respiratory tract infection, cough, epistaxis and diarrhea. The adverse reactions reported for the whole 12-month trial period, which included the open-label extension, were similar in type and frequency to the reactions observed during the 12-week period.
Alfuzosin hydrochloride was not studied in patients below the age of 2.
8.5Geriatric 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 )] .
8.6Renal 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) ].

🆘 Overdosage ▾
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.
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism 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.
12.2Pharmacodynamics 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% Cl) 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.
