What is Cardura?

Cardura is used to treat hypertension (high blood pressure) or to help men that have benign prostatic hyperplasia, as it can help to improve urination. Cardura relaxes the veins and arteries so that blood can more easily pass through them and also helps to relax the muscles in your bladder neck and prostrate, making it easier for you to urinate. Cardura may be prescribed for reasons not stated in this medication guide.

 

Key Facts About Cardura

Cardura is in a group of medications called alpha-adrenergic blockers, and it helps to relax your veins and arteries so that blood can more easily pass through them.

Cardura works by reducing the swelling of your prostate gland, which when swollen, may block the flow of urine. Cardura helps to relax the muscles of the prostate and increase your urine flow.
