Purpose : Benign prostate hyperplasia(BPH) can be treated with ¥á
1-adrenergic blocker that relaxes prostate smooth muscle or 5¥á-reductase
inhibitor that reduces serum dirtydrotestosterone. The efficacy of the combination of 5¥á
-reductase inhibitor(finasteride) and ¥á1-adrenergic blocker(doxazosin) was
evaluated in patients with benign prostate hyperplasia.
Materials and Methods : Eighty five patients with BPH was treated and followed over
6 months and divided into three groups: Group 1(doxazosin 3mg/day), Group
2(finasteride 5mg) and Group 3(combination of both drugs). Initially, all patients were
evaluated by international Prostatic Symptom Score(IPSS: irritative, obstructive, sum, life
quality), uroflowmetry, residual urine, serum prostate specific antigen(PSA) and prostate
weight by transrectal ultrasonography. IPSS, uroflowmetry and complications were
evaluated every month. Residual urine and PSA were assessed at every 3 months,
prostate weight at every 6 months.
Results : In Group 1 and 3, IPSS were more decreased than In Group 2
immediately(p<0.001). In Group 1 and 3, maximal flow rate was more increased than in
group 2 immediately(p<0.001). There was no difference of mean change of residual urine
among three group. In Group 2 and 3, serum prostate specific antigen and prostate
weight were more decreased than in Group 1 (p<0.001).
Conclusions : In medical treatment of BPH, the combination therapy of ¥á
1-adrenergic blocker and 5¥á-reductase inhibitor shows early symptomatic
improvement and decreased prostate weight without significant complications.
