Silodosin is an alpha-1 adrenergic receptor antagonist used to treat benign prostatic hyperplasia (BPH) symptoms. It 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. It relieves the symptoms of BPH by relaxing the muscles of the bladder and prostate.
