Increased blood flow to the penis leads to an erection. Usually, thinking about or touching your penis directly stimulates blood flow. Sildenafil Citrate, which is present in fildena side effects, controls the PDE5 enzyme in the penis and improves blood flow through it. The penis gets a hard erection as a result of this increased blood flow through it. Men can get and sustain an erection with the aid of Cenforce when accompanied with psychological or physical sexual stimulus.

The active component of fildena 100 mg pills is sildenafil citrate. It functions by blocking the PDE5 enzyme, which is in charge of degrading cyclic guanosine monophosphate (cGMP). Sildenafil citrate works by blocking this enzyme, which raises the body's cGMP levels and relaxes the smooth muscles in the penile blood vessels, resulting in an increase in blood flow.
