Cardura® XL (doxazosin mesylate extended release tablets)
Doxazosin works by relaxing blood vessels so that blood passes through them more easily. This helps to lower blood pressure.
Doxazosin is also used to treat benign (noncancerous) enlargement of the prostate (benign prostatic hyperplasia [BPH]).
Doxazosin helps relax the muscles in the prostate and the opening of the bladder. This may help increase the flow of urine and/or decrease the symptoms.
