2. Product Description:
Tamsulosin is a selective α1 receptor antagonist that has
preferential selectivity for the α1A receptor in the prostate
versus the α1B receptor in the blood vessels.
When alpha 1 receptors in the bladder neck and the prostate are
blocked, this causes a relaxation in smooth muscle and therefore
less resistance to urinary flow. Due to this the pain associated
with BPH can be reduced.
It is used in the treatment of difficult urination, a common
symptom of enlarged prostate. Tamsulosin, and other medications in
the class called alpha blockers, work by relaxing bladder neck
muscles and muscle fibers in the prostate itself and make it easier
