Tamsulosin is an alpha1A adrenoceptor blocker. In the prostate gland, bladder and urethra there are specialised cells containing alpha 1A -receptors that cause the muscles in the urethra to tighten. Tamsulosin reduces the action of these specialised cells and relaxes the muscles making it easier to pass water. It acts by relaxing the muscles in the prostate and urethra (the tube that carries urine to the outside), and lets urine pass more readily through the urethra and helps in urination.
Do not take if you:
· are allergic to the active ingredient, tamsulosin or to any of the excipients.
