Definition: Combination medical therapy for an enlarged prostate (benign prostatic hyperplasia)involves combining alpha blockers with 5-alpha-reductase inhibitors to get the effect of both drugs, namely relaxing the prostate gland with the alpha blockers and shrinking it with the 5-alpha-reductase inhibitors.
Examples:
My dad's enlarged prostate gave him more difficulty urinating. One drug no longer seemed adequate. His doctor tried him on combination medical therapy: an alpha blocker plus a 5-alpha reductase inhibitor.
