Fildena 50 mg does not act as an aphrodisiac but supports the body’s natural erection process. This increases the levels of cyclic guanosine monophosphate (cGMP), a substance that relaxes the smooth muscles and dilates blood vessels. PDE5 breaks down cGMP, but Sildenafil in Fildena blocks PDE5, allowing cGMP to accumulate and sustain an erection.
