Benign Prostatic Hyperplasia: Doxazosin, as mesilate (Alfadil XL) is indicated for the treatment of clinical symptoms in benign prostatic hyperplasia (BPH) and for reduced urinary flow associated with BPH. Doxazosin GITS may be used in BPH patients who are either hypertensive or normotensive. While the blood pressure changes in normotensive patients with BPH are clinically insignificant, patients with hypertension and BPH have had both the conditions effectively treated with Doxazosin, as mesilate (Alfadil XL) monotherapy.
