Doxazosin is indicated for the treatment of both the urinary outflow obstruction and the obstructive and irritative symptoms associated with benign prostatic hyperplasia (BPH). Obstructive symptoms are hesitation, intermittency, dribbling, weak urinary stream, and incomplete emptying of the bladder; while irritative symptoms include nocturia, daytime frequency, urgency, and burning. Doxaxosin may be used in nomotensive or hypertensive patients. In normotensive patients with BPH, doxazosin does not appear to significantly lower blood pressure. In hypertensive patients with BPH, both conditions are effectively treated with doxazosin. The long term effects of doxazosin on the incidence of acute urinary obstruction or other complications of BPH or on the need for surgery have not yet been determined. /Included in US product labeling/ /Salt not specified/

Evaluation of atherosclerosis is important in the treatment of hypertension. To evaluate the preventive effects of a small amount of alpha-blockade, arterial and endothelial dysfunction were measured by noninvasive tests, i.e., pulse wave velocity, acceleration plethysmography and strain-gauge plethysmography, in patients with essential hypertension. Fifteen patients (65+/-3 years old) with essential hypertension (WHO stage I or II) were analyzed in this study. We performed noninvasive evaluations to measure aortic stiffness and endothelial dysfunction, in addition to measuring blood pressure, cholesterol profile, and levels of cells adhesion molecules and nitric oxide before and 6 and 12 months after the start of doxazosin treatment (1.0 mg/day). Blood pressure and heart rate did not significantly change during treatment. The pulse wave velocity index was significantly reduced both at 6 (7.72+/-0.23 m/s; p<0.05) and 12 (7.34+/-0.26 m/s; p<0.05) months after the start of treatment compared to the pretreatment level that at baseline. There was also a significant improvement in b/a after 12 months (-0.46+/-0.04; p<0.05) and in d/a after 6 months (-0.38+/-0.03; p<0.05) and 12 months (-0.39+/-0.03; p=0.05) compared to the pretreatment values. Moreover, reactive hyperemia evaluated by strain-gauge plethysmography after 6 months (1.34+/-0.11; p<0.05) and 12 months (1.49+/-0.16; p<0.05) was significantly improved compared to that before treatment, and NOx was significantly increased after 12 months (89.7+/-15.7 micromol/l; p<0.005). These data suggest that a low dose of doxazosin may play an important role in improving arterial stiffness and endothelial dysfunction without changing cardiac hemodynamics. /Salt not specified/

Adverse effects occurring most frequently during doxazosin mesylate therapy for hypertension include dizziness, headache, drowsiness, lack of energy (eg, lethargy, fatigue), nausea, edema, and rhinitis. In patients receiving the drug for benign prostatic hyperplasia (BPH), the most frequent adverse effects are dizziness, headache, fatigue, edema, dyspnea, abdominal pain, and diarrhea. The frequency of adverse effects in controlled clinical trails generally has been lower in patients receiving doxazosin for BPH than in those receiving the drug for hypertension; however, dosages employed for this condition also generally have been lower than those for hypertension. /Salt not specified/
McEvoy, G.K. (ed.). American Hospital Formulary Service- Drug Information 2002. Bethesda, MD: American Society of Health-System Pharmacists, Inc. 2002 (Plus Supplements)., p. 1819
While adverse effects occur frequently in patients receiving the drug, most are mild to moderate in severity, and discontinuance of doxazosin secondary to adverse effects was required in only 7% of patients with hypertension during clinical trials. The principal reasons for discontinuance in patients with hypertension were postural effects in 2% of patients and edema, malaise/fatigue, and heart rate disturbance each in about 0.7% of patients. In controlled clinical trials in patients with hypertension, only dizziness (including postural effects), weight gain, somnolence, and malaise/fatigue occurred at rates significantly greater than those for placebo; postural effects and edema appeared to be dose related. Only dizziness, fatigue, hypotension, edema, and dyspnea occurred significantly more frequently with the drug than placebo in controlled clinical trials for BPH; dizziness and dyspnea appeared to be dose-related. /Salt not specified/

Besides dizziness ..., headache is the most common adverse nervous system effect associated with doxazosin therapy, occurring in about 14 or 10% of patients receiving the drug for hypertension or benign prostatic hyperplasia (BPH), respectively. Somnolence occurs in 5 or 3% of such patients, respectively, and pain in 2% of patients. Nervousness occurs in about 2% of patients receiving doxazosin for hypertension, and insomnia and anxiety occur in 1.2 and 1.1%, respectively, of those receiving the drug for BPH; insomnia occurs in 1% of hypertensive patients. Adverse nervous system effects occurring in 0.5-1% of patients include paresthesia, kinetic disorders, ataxia, hypertonia, hypoesthesia, agitation, depression, and decreased libido. Paresis, tremor, twitching, confusion, migraine, paroniria, amnesia, emotional lability, impaired concentration, abnormal thinking, and depresonalization have been reported in less than 0.5% of patients, but a causal relationship to the drug has not been established. /Salt not specified/

Nausea, diarrhea, and dry mouth are the most common adverse GI effects of doxazosin in hypertensive patients, occurring in 3, 2, and 2% of such patients, respectively, and abdominal pain, diarrhea, dyspepsia, nausea, and dry mouth are the most common in those with benign prostatic hyperplasia (BPH), occurring in 2.4, 2.3, 1.7, 1.5, and 1.4% of such patients, respectively; dyspepsia occurs in 1% of hypertensive patients. Constipation and flatulence occur in 1% of patients receiving the drug for hypertension. Increased appetite, anorexia, fecal incontinence, and gastroenteritis have been reported in less than 0.5% of hypertensive patients but not directly attributed to the drug. Vomiting has been reported during postmarketing experience with doxazosin. /Salt not specified/

Hypertension: Blockade of alpha1-adrenergic receptors by doxazosin results in peripheral vasodilation, which produces a fall in blood pressure because of decreased peripheral vascular resistance. Benign prostatic hyperplasia: Relaxation of smooth muscle in the bladder neck, prostate, and prostate capsule produced by alpha1-adrenergic blockade results in a reduction in urethral resistance and pressure, bladder outlet resistance, and urinary symptoms. /Salt not specified/

Previous studies have demonstrated that the alpha(1)-adrenergic receptor antagonist doxazosin (Dox) inhibits multiple mitogenic signaling pathways in human vascular smooth muscle cells. This broad antiproliferative activity of Dox occurs through a novel mechanism unrelated to its blocking the alpha(1)-adrenergic receptor. Flow cytometry demonstrated that Dox prevents mitogen-induced G(1)-->S progression of human coronary artery smooth muscle cells (CASMCs) in a dose-dependent manner, with a maximal reduction of S-phase transition by 88+/-10.5% in 20 ng/mL platelet-derived growth factor and 1 micromol/L insulin (P+I)-stimulated cells (P<0.01 for 10 micromol/L Dox versus P+I alone) and 52+/-18.7% for 10% FBS-induced mitogenesis (P<0.05 for 10 micromol/L Dox versus 10% FBS alone). Inhibition of G(1) exit by Dox was accompanied by a significant blockade of retinoblastoma protein (Rb) phospstimulated quiescent CASMCs to progress through G(1) and enter the S phase. E2F-mediated G(1) exit was not affected by Dox, suggesting that it targets events upstream from Rb hyperphosphorylation. Downregulation of the cyclin-dependent kinase inhibitory protein p27 is important for maximal activation of G(1) cyclin/cyclin-dependent kinase holoenzymes to overcome the cell cycle inhibitory activity of Rb. In Western blot analysis, p27 levels decreased after mitogenic stimulation (after P+I, 43+/-1.8% of quiescent cells [P<0.01 versus quiescent cells]; after 10% FBS, 55+/-7.7% of quiescent cells [P<0. 05 versus quiescent cells]), whereas the addition of Dox (10 micromol/L) markedly attenuated its downregulation (after P+I, 90+/-8.3% of quiescent cells [P<0.05 versus P+I alone]; after 10% FBS, 78+/-8.3% of quiescent cells [P<0.05 versus 10% FBS alone]). Furthermore, Dox inhibited cyclin A expression, an E2F regulated gene that is essential for cell cycle progression into the S phase. The present study demonstrates that Dox inhibits CASMC proliferation by blocking cell cycle progression from the G(0)/G(1) phase to the S phase. This G(1)-->S blockade likely results from an inhibition of mitogen-induced Rb hyperphosphorylation through prevention of p27 downregulation. /Salt not specified/
