What is Cardura

Cardura is in a class of drugs called alpha-adrenergic blockers. Cardura causes the blood vessels (veins and arteries) to relax and expand, which allows blood to pass more easily through them.

Cardura is used to treat hypertension (high blood pressure). Cardura is also used to treat benign prostatic hyperplasia (enlarged prostate). It relaxes the muscles in the prostate and bladder neck, making it easier to urinate.

Cardura may also be used for purposes other than those listed in this medication guide.
