Alfuzosin is a type of medicine called an alpha-blocker. This is used to relieve the urinary symptoms of an enlarged prostate gland or called benign prostate hyperplasia.
As men gets older, benign prostate hyperplasia is a common condition. An enlarged prostate gland can cause uncomfortable urinary symptoms. It can also cause urinary tract, bladder, or kidney problems. The severity of symptoms in people who have prostate gland enlargement varies. But, symptoms tend to slowly worsen over time. Common signs and symptoms of benign prostate hyperplasia include:
- Increased frequency of urination at night
- Frequent or urgent need to urinate
- Weak urine stream or a stream that stops and starts
- Difficulty starting urination
- Inability to completely empty the bladder
- Dribbling at the end of urination
Less common signs and symptoms include:
- Blood in the urine
- Inability to urinate
- Urinary tract infection
The size of your prostate doesn’t necessarily determine the severity of your symptoms. Some men with only slightly enlarged prostates can have significant symptoms, while other men with very enlarged prostates can have only minor urinary symptoms. In some men, symptoms eventually stabilize and might even improve over time.
The prostate gland is located beneath your bladder. The tube that transports urine from the bladder out of your penis passes through the center of the prostate. When the prostate enlarges, it begins to block urine flow. Most men have continued prostate growth throughout life. In many men, this continued growth enlarges the prostate enough to cause urinary symptoms or to significantly block urine flow. Most men with an enlarged prostate don’t develop these complications. However, acute urinary retention and kidney damage can be serious health threats. Having an enlarged prostate is not believed to increase your risk of developing prostate cancer.
How does Alfuzosin work?
Alfuzosin works by blocking alpha receptors that are found in the muscle in the prostate gland.
The prostate gland, lies at the top of the tube connecting the bladder to the outside. The prostate gland often enlarges with advancing age pressing on the urethra and obstructing the flow of urine from the bladder. Alfuzosin blocks alpha receptors in the muscle of the prostate gland which causes the muscle in the prostate to relax. This allows urine to flow freely past the prostate and relieves the urinary symptoms.
