UroXatral OD
UroXatral OD Uses, Dosage, Side Effects, Food Interaction and all others data.
UroXatral OD Hydrochloride is a selective antagonist of post-synaptic a1 adrenoreceptors, which are located in the prostate, bladder base, bladder neck, prostatic capsule, and prostatic urethra. UroXatral OD Hydrochloride relaxes the tone of the prostate smooth muscle, prostate capsule, bladder neck and proximal urethra. It competitively and selectively binds to the post synaptic a1-adrenergic receptors in the lower urinary tract. It also relaxes sympathetic nervous stimulation, reduces resting urethral pressure and inhibits urethral hypertonia-induced sympathetic nervous stimulation. As an uroselective agent, UroXatral OD Hydrochloride preferentially binds to prostatic a1 receptors, blockage of these receptors result in reduction of BPH symptoms, improvement of urine flow and decreased potential for hypertensive events.
By selectively inhibiting alpha adrenergic receptors in the lower urinary tract, alfuzosin causes smooth muscle relaxation in the bladder neck and prostate, improving urine flow, thereby reducing BPH symptoms. Additionally, alfuzosin reduces the vasoconstrictor effect of catecholamines (epinephrine and norepinephrine), leading to peripheral vasodilation. This leads to a risk of postural hypotension/syncope, and prescribing information warns that caution should be exercised in patients who take nitrates, antihypertensives, or have experienced decreased blood pressure after using other medications.

Uses
UroXatral OD Hydrochloride is used for the treatment of the signs and symptoms of benign prostatic hyperplasia(BPH), lower urinary tract symptoms (LUTS) including urinary frequency, nocturia, incomplete emptying and urinary hesitancy associated with BPH.
UroXatral OD is also used to associated treatment for these conditions: Benign Prostatic Hyperplasia (BPH)
How UroXatral OD works
Alpha(1)-adrenoreceptors are found in the prostate, bladder base, bladder neck, prostatic capsule, and prostatic urethra; their activation may lead to contraction of smooth muscle and urinary symptoms in patients with BPH. UroXatral OD selectively binds to and inhibits alpha(1)-adrenergic receptors in the lower urinary tract. This leads to the relaxation of smooth muscle in both the prostate and bladder neck, resulting in the improvement in urine flow and a reduction of urinary symptoms.
Dosage
UroXatral OD dosage
The recommended dosage is one 10 mg UroXatral OD Hydrochloride tablet daily to be taken immediately after the same meal each day. The tablets should not be chewed or crushed.
UroXatral OD Hydrochloride tablet should be swallowed whole.
Side Effects
This formulation is generally well tolerated. However the following adverse events have been reported include abdominal pain, dyspepsia, constipation, nausea, impotence, bronchitis, sinusitis and pharyngitis.
Toxicity
The oral LD50 of alfuzosin is 2300 mg/kg in male mice and 1950 mg/kg in female mice. An overdose of alfuzosin can cause hypotension. Cardiovascular support should be initiated immediately. The patient should be kept in the supine position to aid in restoring pressure and managing heart rate. Fluid resuscitation should also be considered in severe cases; sometimes, vasopressors are required. Renal function should be monitored frequently. Dialysis may not be of benefit to alfuzosin protein binding of up to 90%.
Precaution
UroXatral OD Hydrochloride should not be given to patients with moderate or severe hepatic insufficiency. Caution should be exercised when UroXatral OD is administered in patients with severe renal insufficiency. If symptoms of angina pectoris should newly appear or worsen, UroXatral OD Hydrochloride should be discontinued.
Interaction
UroXatral OD may interact with other alpha-blockers, Atenolol, Cimetidine, Diltiazem, Ketoconazole and Ritonavir.
Food Interaction
- Take after a meal. Take alfuzosin after the same meal everyday. Do not take on an empty stomach.
[Moderate] ADJUST DOSING INTERVAL: Administration of alfuzosin with food enhances oral bioavailability.
According to the manufacturer, extent of absorption is 50% higher when administered under fed conditions compared to fasting conditions.br>
MANAGEMENT: To ensure maximal oral absorption, alfuzosin should be administered with or immediately after a meal.
UroXatral OD Alcohol interaction
[Moderate] GENERALLY AVOID:
The concurrent use of ethanol and alpha-1 adrenergic blockers may cause increased hypotensive effects.
Patients with aldehyde dehydrogenase deficiencies (primarily Asians) may be at a higher risk of this interaction.
The mechanism has not been determined.
Data exist for prazosin and other alpha adrenergic blockers are expected to interact also.
In addition, any patients taking alpha adrenergic blockers may experience excessive orthostatic hypotension with ethanol ingestion, due to ethanol's unopposed vasodilatory effects in the presence of alpha adrenergic blockade.
Patients who develop
a flushing reaction after ethanol ingestion (indicates a possible aldehyde dehydrogenase deficiency) should be advised to avoid ethanol or limit their intake.
All patients should be warned about the possibility of orthostatic hypotension with concurrent ethanol use.

UroXatral OD Disease Interaction
Major: hepatic impairmentModerate: QT prolongation, renal impairment, hypotension, cataracts
Volume of Distribution
The volume of distribution of alfuzosin after intravenous administration in healthy volunteers is about 3.2 L/kg. UroXatral OD distributes heavily to the tissues of the prostate.
Elimination Route
UroXatral OD is readily absorbed in the gastrointestinal tract and the absolute bioavailability under fed conditions is 49%. In patients over 75 years of age, alfuzosin is absorbed more rapidly and peak plasma levels are higher. One source mentions a bioavailability of 64%. After multiple doses under fed conditions, Cmax is achieved in 8 hours. Cmax and AUC0-24 values are about 13.6 ng/mL and 194 ng·h/mL, respectively. Steady-state plasma concentrations are achieved after the second dose and are 1.2 to 1.6 times higher than after a single dose. With the extended-release formulation, alfuzosin release is sustained over 20 hours with a rate of dissolution ranging between 2 and 12 hours.
Half Life
The apparent elimination half-life of alfuzosin after oral administration is about 10 hours. The terminal half-life is 3-5 hours.
Clearance
Exercise caution if renal clearance is < 30 mL/min. The clearance of alfuzosin is increased in renal insufficiency (with or without dialysis), due to an increase in the free fraction.
Elimination Route
It is partially metabolised and excreted mainly in the bile and faeces. Following oral administration of a radiolabeled alfuzosin solution, the detection of radioactivity after one week was 69% in the feces and 24% in the urine.
Pregnancy & Breastfeeding use
UroXatral OD Hydrochloride is not indicated for use in pregnant and lactating mother.
Contraindication
UroXatral OD Hydrochloride tablet is contraindicated for hypersensitivity to UroXatral OD Hydrochloride, history of orthostatic hypotension, combination with other alpha-1 receptor blockers, hepatic insufficiency.
Special Warning
Efficacy of UroXatral OD Hydrochloride has not been demonstrated in children aged 2 to 16 years. Therefore UroXatral OD Hydrochloride is not indicated for use in the paediatric population.
Acute Overdose
Overdose of UroXatral OD Hydrochloride should 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.
Storage Condition
Store in a cool and dry place, protected from light
