(generic name: tamsulosin) refers to a class of medication called alpha-adrenergic blockers.
Tamsulosin helps to ease urinating process by relaxing prostate muscles and bladder neck. Most often Tamsulosin is used to help urinate men with enlarged prostate.
(active substance of Flomax) was created by Japanese company Yamanouchi Pharmaceuticals and first appeared on the market in 1996 under the brand name Flomax. In October 2009 the U.S. patent for Flomax has expired and in march 2010 FDA approved generic version of Flomax which is sold now under different trade names.
Tamsulosin is an oral prescription medication and it should not be sold over the counter (no prescription).
The mechanism of action
Tamsulosin blocks alpha receptors (the main cause of trouble urinating) in the bladder neck. This causes a relaxation in smooth muscle and almost eliminates the pain caused by BPH and resistance to urinary flow.
Flomax or tamsulosin hydrochloride capsules/pills
are prescribed to treat the symptoms and signs of benign prostatic hyperplasia (BPH) or enlarged prostate. Sometimes tamsulosin is used to treat kidney stones disease. In both disorders the action of the medication is absolutely the same – there is a need to relax the muscles by alpha antagonist.
