Fildena 100 contains sildenafil citrate as its active ingredient, a potent and selective inhibitor of the enzyme phosphodiesterase type 5 (PDE5). By inhibiting PDE5, Fildena 100 mg enhances the levels of cyclic guanosine monophosphate (cGMP), promoting increased blood flow to the penile region during sexual stimulation. This physiological response results in a robust and sustainable erection.
