Abstract The effects of six weeks of treatment with the selective peripheralα 1-adrenoceptor blocker terazosin, or the selectiveβ 1-adrenoceptor blocker atenolol on blood pressure, exercise performance and blood lipid profile were compared in a single-blind, randomized, crossover study of 17 patients with mild-to-moderate essential hypertension. Although both drugs significantly reduced blood pressure at rest, atenolol caused a larger fall in supine blood pressure (11/11 and 7.5/7.0 mmHg, atenolol and terazosin, respectively;p 〈 0.001). Both treatments controlled the pressor response to exercise, although a greater reduction in diastolic blood pressure was observed at the end of exercise on terazosin (74.0 ± 5.7 and 91.6 ± 4.0 mmHg, terazosin and atenolol, respectively;p 〈 0.01). Alpha1-blocker therapy was not associated with any measurable improvement or deterioration in cardiopulmonary performance and exercise duration. Unlike atenolol, terazosin therapy had the potentially beneficial effect of reducing serum total cholesterol levels and increasing the high-density lipoprotein-cholesterol/low-density lipoprotein-cholesterol ratio.
