Abstract: A pharmaceutical composition including active ingredients of (R)-5-(2-{[2-(2-ethoxyphenoxy)ethyl]amino}propyl-2-methoxybenzene-1-sulfonamide and (1S)-1-phenyl-1,2,3,4-tetrahydroisoquinoline-2-carboxylic acid (3R)-quinuclidin-3-yl ester, or their pharmaceutically acceptable salts, provides improvement of lower urinary tract symptoms associated with prostatic hypertrophy. The active ingredients may be administered either simultaneously or at a time interval. The pharmaceutical composition also provides significant improvement of lower urinary tract symptoms associated with benign prostatic hyperplasia having a substantial storage component.
