Why does Filitra work for erectile dysfunction?
Filitra works for erectile dysfunction because it contains the active ingredient vardenafil, which is a type of PDE5 inhibitor. Filitra medication works by blocking the enzyme phosphodiesterase type 5 (PDE5), which is responsible for breaking down cyclic guanosine monophosphate (cGMP). cGMP helps relax the smooth muscles in the penis and allows for increased blood flow.
