DALLAS March 3, 2010 Like any successful team effort, the best qualities of two drugs commonly prescribed for enlarged prostate yielded better results than either of the medicines alone, according to a new study from UT Southwestern Medical Center.
The findings, published in a recent issue of the journal European Urology, compared treatments for three groups of study participants with enlarged prostates over four years. The study, which included more than 4,800 men, is one of the first to compare single and combo medication regimens in such a large group.
The first group of study participants received the drug dutasteride; the second group received tamsulosin; and the third received a combination of the two medicines.
"We found the combination therapy to be superior at reducing risk of BPH progression," said Dr. Claus Roehrborn, chairman of urology at UT Southwestern and lead author of the study. "The two medications joined forces in terms of symptom control. On the strengths of both dutasteride and tamsulosin, participants reported fewer symptoms, and we observed a 25 percent reduction in prostate volume."
Dr. Roehrborn added that subjects who received the combination therapy also showed a 50 percent reduction of prostate-specific antigen (PSA), a protein produced by both cancerous and noncancerous prostate tissue. PSA levels can be an indication of increased risk of cancer because cancer cells usually make more PSA than do benign cells, causing PSA levels in the blood to rise. Should PSA levels continue to rise after beginning therapy, patients should be monitored closely because the combination medicines do lower PSA readings, Dr. Roehrborn said.
Enlarged prostate, also called benign prostatic hyperplasia (BPH), is a common urologic condition that affects about 50 percent of men between the ages of 51 and 60 and up to 90 percent of men over the age of 80.
Symptoms of the condition can be prolong
