Fildena 200 helps men with erectile dysfunction. Viagra belongs to the group of medications known as phosphodiesterase-5 (PDE-5) inhi***ors. These drugs prevent phosphodiesterase type-5 from working too quickly. The urethra is one location where this enzyme works.

A man may have erectile dysfunction, which prevents his penis from hardening and expanding, if he has trouble getting or maintaining an erection. An erection occurs when a man is sexually stimulated because his body typically sends more blood to his penis. The use of Viagra helps maintain an erection after penis massage. It accomplishes this by managing an enzyme. Without physical stimulation of the penis, such as occurs during sexual activity, Viagra will not function to cause an erection.
