Silodosin


Silodosin is used in men to treat the symptoms of an enlarged prostate (benign prostatic hyperplasia; BPH), which include difficulty urinating (hesitation, dribbling, weak stream, and incomplete bladder emptying), painful urination, and urinary frequency and urgency. Silodosin is in a class of medications called alpha-blockers. It relieves the symptoms of BPH by relaxing the muscles of the bladder and prostate.
