How Flomax Works: Due to the mechanism of action of Flomax, the pain associated with benign prostatic hyperplasia can be reduced. Flomax is a selective 1a alpha blocker. Therefore, Flomax acts as a selective 1 receptor antagonist. This drug has preferential selective nature towards the 1b receptor in the blood vessels and 1A receptor in the prostate. Thus, due to the action of Flomax the alpha 1 receptors are blocked in the prostate and in the bladder neck region of the individual. This results in the less resistance towards the urine flow of the body due to relaxation of the smooth muscles. Hence, the pain associated with benign prostatic hyperplasia is greatly reduced.
