Cardura (Doxazosin)
Cardura (Doxazosin)
Cardura (Doxazosin), is an alpha-blocker medication commonly prescribed to treat high blood pressure (hypertension) and symptoms of an enlarged prostate (benign prostatic hyperplasia or BPH). It works by relaxing blood vessels and muscle cells in the prostate and bladder, easing the flow of blood and urine. Through this dual mechanism, Cardura effectively manages both cardiovascular and urinary issues, providing a comprehensive treatment option.
