Fildena 200 mg works by enhancing blood flow to specific areas of the body, primarily aiding men experiencing erectile dysfunction (ED). It contains sildenafil citrate, a PDE5 inhibitor that relaxes blood vessel walls, allowing increased blood circulation to the penile upon sexual stimulation. By blocking the PDE5 enzyme, Fildena maintains higher levels of cyclic guanosine monophosphate (cGMP), which promotes smooth muscle relaxation in the penile tissues. This improved blood flow supports a sustained erection, helping men achieve and maintain sexual satisfaction. However, Fildena 200 mg should be taken under medical supervision to ensure safety and effectiveness for the individual.
