What is Cardura?

Cardura prescription medication belongs to a class of drugs known as alpha-blockers. The generic name of Cardura medication is Doxazosin. Cardura (doxazosin) comes in immediate-release tablet form and can be taken with or without food. The Cardura tablet treats high blood pressure and benign prostatic hyperplasia (BPH). Cardura medicine works by relaxing the blood vessels (veins and arteries) so that blood passes through them more easily. This action helps in lowering blood pressure. Cardura pills also help relax the prostate muscles and the bladder’s opening. This action helps increase the urine flow and/or reduce the symptoms, but it will not shrink the prostate.
