This study sought to assess the efficacy, tolerability, and effect of
finasteride on health-related quality of Life (HRQL) in a diverse popu
lation of men with moderate-to-severe symptomatic benign prostatic hyp
erplasia (BPH). This double-blind study evaluated finasteride and plac
ebo for 12 months in 2342 men with BPH (16.2% black, 14.5% Hispanic, 6
9.3% Caucasian/other) in a community-based setting. At 3-month interva
ls, urinary symptoms were measured by use of the American Urologic Ass
ociation symptom index. HRQL was assessed by use of the BPH impact ind
ex (BIE), which evaluated degree of bother, worry, physical discomfort
, and restriction in activities as a result of urinary symptoms. Addit
ional questions regarding activities of living were administered, and
global assessments of change in urologic status were performed by both
patients and investigators. Com pared with placebo, patients treated
with finasteride had a statistically significant decrease in symptom s
cores when first measured at month 3. Symptom scores continued to impr
ove in finasteride-treated patients throughout the study; at month 12,
the mean decrease in symptom scores in the finasteride-treated patien
ts was -4.8 compared with -3.4 for placebo patients (P = 0.0001). Stat
istically significant differences in favor of finasteride also were no
ted at month 12 on the BII (P = 0.0465), and finasteride-treated patie
nts experienced less interference with activities of living (P = 0.051
8). Patient and investigator global assessments of urologic status sho
wed that significantly more patients in the finasteride group consider
ed themselves improved and were considered improved by investigators a
t month 12 (P = 0.000). Finasteride was generally well tolerated. The
incidence of drug-related sexual adverse experiences was significantly
higher in the finasteride group (P = 0.000), but led to withdrawal in
only 1.5% of patients. The demonstrated efficacy and tolerability of
finasteride in reducing symptoms and improving quality of life confirm
observations of previous trials and make finasteride a highly desirab
le treatment option for many men with symptomatic BPH.
