Fildena belongs to a class of medications called phosphodiesterase type 5 (PDE5) inhibitors. It works by blocking the action of the enzyme PDE5, which is responsible for the degradation of a substance called cyclic guanosine monophosphate (cGMP). By inhibiting PDE5, Fildena Pill helps to increase the levels of cGMP, which in turn promotes relaxation of the smooth muscles in the penis and increases blood flow to the Erectile Dysfunction, leading to an erection.
