title: [Doxazosin for the treatment of arterial hypertension].
abstract: 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.
