What is doxazosin (Cardura, Cardura XL)?
Doxazosin is in a group of drugs called alpha-adrenergic (AL-fa ad-ren-ER-jik) blockers. Doxazosin relaxes your veins and arteries so that blood can more easily pass through them. It also relaxes the muscles in the prostate and bladder neck, making it easier to urinate.
