In practice, some of the major problems for the physician who treats hypertension are patients who are resistant to treatment or who have other complicating risk syndromes. Therefore the overall efficacy of an antihypertensive agent must include an assessment of effect in patients with serious ancillary problems. In this article, doxazosin is reviewed for its efficacy in the treatment of severe essential hypertension and specific complications or conditions of mild or moderate essential hypertension, namely, left ventricular hypertrophy, hyperlipidemia, noninsulin-dependent diabetes mellitus, renal insufficiency, pheochromocytoma, chronic obstructive pulmonary disease, peripheral vascular disease, and smoking. Doxazosin is particularly efficacious in many specific subgroups of patients with hypertension, and the results of relevant studies are discussed.

Hypertension is often associated to other risk factors, such as abnormal lipid and carbohydrate metabolism, which should be considered for the choice of antihypertensive drug treatment. Doxazosin is a postsynaptic alpha-1 adrenoceptor blocker suitable for once a day treatment regime. It seems to induce fewer side effects than older drugs of the same class and it may improve lipid and carbohydrate profile, thereby reducing the risk of coronary artery disease. To verify its effects on blood pressure, serum lipids and glucose tolerance, doxazosin (1-8 mg od) was given for 8 weeks to 32 patients suffering from essential hypertension, of whom 16 had fasting serum cholesterol higher than 6 mmol/l and/or fasting serum triglycerides higher than 1.9 mmol/l. Sitting and standing blood pressure were significantly reduced (from 163 +/- 18/101 +/- 6 mmHg to 147 +/- 19/94 +/- 8, p less than 0.001 and from 162 +/- 18/107 +/- 9 to 145 +/- 18/95 +/- 8, p less than 0.001, respectively) at a mean daily dose of 5 mg. Normotension or a good hypotensive response was achieved in 60% of the patients. The daily dose which turned out to be effective in 50% of the patients was 7 mg. The drug treatment was well tolerated and orthostatic hypotension was never observed either on starting treatment or on increasing dosage. Blood lipids and glucose tolerance were not significantly affected. Doxazosin is therefore an effective antihypertensive agent suitable for use in patients with essential hypertension alone or combined with hyperlipidemia.

Doxazosin, a once daily alpha-blocking drug has been demonstrated to reduce both BP and hyperlipidaemia, related risk factors for premature vascular disease. This study was designed to see if a low fat diet altered the favourable effect of doxazosin on blood lipids in adults with mild to moderate hypertension and mild to moderate hypercholesterolaemia (5.6-8.0 mmol/l). Following a six week period on a low fat diet, patients were randomly allocated to additional doxazosin (2-8 mg/day) or enalapril (5-20 mg/day) treatment for a further 10 weeks. Forty-four of 55 subjects completed the study. A low fat diet reduced mean body weight by 2 kg without significantly altering blood lipids (total and HDL cholesterol, triglycerides). Doxazosin (4.5 +/- 2.9 mg/day) and enalapril (12.5 +/- 6.5 mg/day) produced a comparable lowering of sitting and standing BP at all visits and also produced similar 24h BP control. The expected increase in HDL cholesterol concentration previously noted in this patient population in association with doxazosin treatment was not detected suggesting that the low cholesterol-high carbohydrate diet, at least acutely, attenuates this potentially beneficial effect on plasma lipids. In summary, doxazosin has a comparable tolerability and BP lowering ability to enalapril. However, its ability to increase HDL cholesterol may be reduced in patients on low fat diets.

The purpose of this paper is to review the role of doxazosin, a long-acting alpha(1)-blocker, as a component of combination therapy for patients with stage 1 and stage 2 hypertension and for patients with concomitant hypertension and hyperlipidemia or glucose intolerance. Recent studies that evaluated doxazosin as combination therapy in the treatment of patients with inadequately controlled hypertension and patients with concomitant hypertension and other disorders were reviewed. Data extraction was based on the tolerability and efficacy data of doxazosin in patients with hypertension. Compared with placebo, doxazosin combination therapy leads to significant improvements in sitting and standing blood pressure. Doxazosin is well tolerated, with only minor adverse effects (e.g., headache, dizziness) as the most commonly reported treatment-related complications. The studies described demonstrate that doxazosin is effective as combination therapy for patients with stage 1 and stage 2 hypertension. The positive effects of doxazosin on serum lipids make combination therapy with doxazosin an attractive treatment option for patients who have concomitant hyperlipidemia or glucose intolerance.
