Doxazosin tablets are indicated for the treatment of both the urinary outflow obstruction and obstructive and irritative symptoms associated with BPH: obstructive symptoms (hesitation, intermittency, dribbling, weak urinary stream, incomplete emptying of the bladder) and irritative symptoms (nocturia, daytime frequency, urgency, burning). Doxazosin may be used in all BPH patients whether hypertensive or normotensive. In patients with hypertension and BPH, both conditions were effectively treated with doxazosin monotherapy. Doxazosin provides rapid improvement in symptoms and urinary flow rate in 66 to 71% of patients. Sustained improvements with doxazosin were seen in patients treated for up to 14 weeks in double-blind studies and up to 2 years in open-label studies. Doxazosin tablets are also indicated for the treatment of hypertension. Doxazosin may be used alone or in combination with diuretics, beta-adrenergic blocking agents, calcium channel blockers or angiotensin-converting enzyme inhibitors. Doxazosin

CLINICAL PHARMACOLOGY
PHARMACODYNAMICS
BENIGN PROSTATIC HYPERPLASIA (BPH)
Benign prostatic hyperplasia (BPH) is a common cause of urinary
outflow obstruction in aging males.

prostatic stroma. However, the severity of BPH symptoms and the degree
of urethral obstruction do not
