Multicenter Study Comparative Study Clinical TrialDoxazosin added to single-drug therapy in hypertensive patients with benign prostatic hypertrophy.
The purpose of this study was to evaluate the efficacy and safety of the addition of doxazosin in the treatment of hypertensive patients who are being treated on another antihypertensive drug. The open-labeled, noncomparative, multicenter study was carried out in 2363 male hypertensive outpatients > 40 years of age, under reasonable control with single antihypertensive drug treatment (diastolic blood pressure < 95 mm Hg), and diagnosed with benign prostatic hypertrophy. Doxazosin was started at a dose of 1 mg/day, which was increased at 2-week intervals to 2 mg/day and 4 mg/day. ⋯ The patients who experienced adverse effects were older and their final blood pressures were lower. The results of this open-label study suggest that the addition of doxazosin to another antihypertensive drug in hypertensive patients with benign prostatic hypertrophy is well tolerated and leads to a reduction in prostatic symptoms. The additional beneficial effects on blood pressure suggest that the use of doxazosin may provide a rational approach to this category of patients.(c)2001 Le Jacq Communications, Inc.
