What Is Cardura Used For?
What is Cardura used for? This prescription drug helps lower high blood pressure and treat symptoms of an enlarged prostate. It blocks certain nerves to the muscles of the prostate and bladder in order to relax them. The drug lowers blood pressure by relaxing the blood vessels so that blood flows through them more easily. Cardura is used for off-label reasons as well, such as for congestive heart failure.
Cardura® (doxazosin mesylate) is a prescription medicine that has been licensed for controlling high blood pressure and for treating an enlarged prostate. Cardura is part of a class of medicines called alpha blockers.
The prostate gland, located below the bladder, is part of the male reproductive system. The urethra (the canal that takes urine out of the body) runs through the prostate.
An enlarged prostate (known medically as benign prostatic hyperplasia, benign prostatic hypertrophy, or BPH) is common among older men. The prostate begins growing during puberty and continues to grow throughout most of adulthood. Usually, this is not a problem until men reach their 50s or 60s. When the prostate becomes too large, it can press against the urethra, causing problems with urination. Specific BPH symptoms may include frequent urination (which is especially noticeable at night) and difficulty emptying the bladder completely when urinating.
One of the most common ways to detect an enlarged prostate is with the digital rectal exam. During a digital rectal exam, the doctor inserts a gloved finger into the rectum to feel the size and shape of the prostate. Some men can have a BPH diagnosis without having any symptoms.
Treatment for BPH includes "watchful waiting" (doing nothing, especially if symptoms are not bothersome), medication, and surgery. Cardura is one of the medications given for BPH. It works by blocking alpha-1 receptors, which are certain nerves to the muscles of the prostate and bladder neck (where urine leaves the bladder). Blocking these signals helps to relax the muscles, thus relieving the symptoms of BPH. While Cardura does not shrink the prostate, as some other BPH medications do, it does work quickly to relieve the symptoms of an enlarged prostate. However, Cardura is not a cure for BPH.
