Medically reviewed by  A Ras MD.

What is Uroxatral?

Uroxatral is a prescription medicine that is called an “alpha-blocker”. Uroxatral is used in adult men to treat the symptoms of benign prostatic hyperplasia (BPH). Uroxatral may help to relax the muscles in the prostate and the bladder which may lessen the symptoms of BPH and improve urine flow.

Before prescribing Uroxatral, your doctor may examine your prostate gland and do a blood test called a prostate specific antigen (PSA) test to check for prostate cancer. Prostate cancer and BPH can cause the same symptoms. Prostate cancer needs a different treatment.

Uroxatral is not for use in women or children.

Some medicines called “alpha-blockers” are used to treat high blood pressure. Uroxatral is not for the treatment of high blood pressure.

Description

Each UROXATRAL extended-release tablet contains 10 mg alfuzosin hydrochloride as the active ingredient. Alfuzosin hydrochloride is a white to off-white crystalline powder that melts at approximately 240°C. It is freely soluble in water, sparingly soluble in alcohol, and practically insoluble in dichloromethane.

Alfuzosin hydrochloride 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 C19H27N5O4•HCl. The molecular weight of alfuzosin hydrochloride is 425.9. Its structural formula is:

The tablet also contains the following inactive ingredients: colloidal silicon dioxide (NF), ethylcellulose (NF), hydrogenated castor oil (NF), hydroxypropyl methylcellulose (USP), magnesium stearate (NF), mannitol (USP), microcrystalline cellulose (NF), povidone (USP), and yellow ferric oxide (NF).

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.

What is the most important information I should know about Uroxatral?

Uroxatral can cause serious side effects, including a sudden drop in blood pressure, especially when you start treatment. This may cause you to faint, or to feel dizzy or lightheaded.

• Your risk of having this problem may be increased if you take Uroxatral with certain other medicine that lowers blood pressure:
  • medicines for high blood pressure
  • a nitrate medicine for angina

  Ask your doctor if you are not sure if you are taking one of these medicines.

• Do not drive, operate machinery, or do any dangerous activities until you know how Uroxatral affects you. This is especially important if you already have a problem with low blood pressure or take medicines to treat high blood pressure.
• If you begin to feel dizzy or lightheaded, lie down with your legs and feet up. If your symptoms do not improve call your doctor.
