“…In hypertensive patients, doxazosin lowers blood pressure by selectively inhibiting post-junctional a 1 -adrenergic receptors and antagonizing the stimulant activity of noradrenaline, thereby decreasing systemic vascular stress (Brown & Dickerson, 1991;Englert & Barlage, 1991;Fulton et al, 1995).…”

Men are at greater risk of cardiovascular and renal diseases than women. Several hypertensive rat models also exhibit gender differences in blood pressure. Although the mechanisms responsible for these gender differences are not clear, androgens have been shown to promote hypertension. Testosterone is produced by Leydig cells under the regulation of catecholamines acting through both alpha- and beta-adrenoceptors. Some investigators have postulated a putative role of angiotensin II (Ang II) in modulating the action of gonadotropin in Leydig cells, inhibiting testosterone production. In the present work, we analysed the potential mechanism by which the testicular renin-angiotensin system (RAS) decreases the serum circulating levels of testosterone after the in vivo administration of the long-acting selective alpha(1)-adrenergic receptor antagonist doxazosin. RAS was analysed through assessment of the activity of its proteolytic regulatory enzymes. We can conclude that the testicular testosterone production, at least in rat, is regulated by catecholamines through a mechanism involving alpha(1)-adrenergic receptors and RAS, with a putative role for Ang III. Because doxazosin is usually used as a pharmacological therapy in the treatment of hypertension and benign prostatic hyperplasia, our results could also indicate that its benefits are due, at least in part, to decreased serum circulating levels of testosterone.

“…Studies with classical α 1 -adrenoceptor antagonists (e.g. doxazosin and terazosin) have reported that their blood pressure-lowering effects may be enhanced in patients with concomitant antihypertensive treatment [15, 16, 17, 18, 19]. In normotensive patients with LUTS suggestive of BPO, these drugs can also cause blood pressure reductions which are small but significantly greater than with placebo [19, 20, 21].…”

“…There are many 'beyond blood pressure' beneficial effects of doxazosin ( Table 2 ) [6][7][8][9]11,14,18,22,31,33,34,39,43,45,48,53,[55][56][57][58][59][60][61][62][63][64][65][66][67][68][69][70][71] . This agent in either form exerts favourable effects on serum lipid levels by decreasing total and low-density lipoprotein (LDL) cholesterol and increasing the high-density lipoprotein (HDL) cholesterol level [7,8,22,31,53,61,63,72,73] .…”

In these studies doxazosin in either standard or extended-release formulation was added as a second- or third-line agent. The two formulations of doxazosin, although chemically identical, appear to differ in some other effects. A large proportion of patients demonstrated a favourable blood pressure response with relatively few treatment-associated side effects showing that this drug appears to be a valuable add-on antihypertensive treatment option. Doxazosin reduces blood pressure and additionally influences other risk factors of coronary heart disease. However, it should be clearly stated that the clinical role of 'beyond blood pressure' effects of doxazosin are largely undetermined.
