It does not shrink the prostate, but it works by relaxing the muscles in the prostate and the bladder. This helps to relieve symptoms of BPH such as difficulty in beginning the flow of urine, weak stream, and the need to urinate often or urgently (including during the middle of the night).Tamsulosin belongs to a class of drugs known as alpha blockers.Do not use this medication to treat high blood pressure.
