High-dose terazosin therapy (5mg) in Korean patients with lower urinary tract symptoms with or without concomitant hypertension: a prospective, open-label study.
OBJECTIVE
We determined the efficacy and safety of a relatively high dose of terazosin (5mg) in Korean patients with lower urinary tract symptoms (LUTS), with or without concomitant hypertension.


METHODS
From July to December 2006, 200 men who consecutively presented with LUTS were prospectively studied. Eight weeks after treatment, blood pressure (BP), uroflowmetry, and International Prostate Symptom Score (I-PSS) were assessed. For analysis purposes, patients were stratified according to concomitant hypertension. Of the 200 patients, 173 completed the scheduled eight-week treatment period.


RESULTS
At baseline, no differences were evident in the two groups in terms of I-PSS, Qmax, PVR and BP. After eight weeks of treatment-although I-PSS and uroflowmetry parameters were not significantly different in the two groups-systolic and diastolic BP in the non-hypertensive control group were higher than in the hypertensive group (p= 0.001 and p=0.0100, respectively). Changes in I-PSS, uroflowmetry parameters, and BPs measured at week eight post- treatment commencement did not significantly differ between the two groups. Moreover, the addition of 5mg of terazosin to antihypertensives did not cause a significant reduction in either systolic or diastolic BP in either group.


CONCLUSIONS
Adding terazosin to existing antihypertensive regimens did not seem to increase the incidence of adverse events. Our findings suggest that 5mg terazosin is effective and that it has an acceptable safety profile as an add-on therapy for patients with LUTS and concomitant hypertension.
