Fildena 120 mg can be an effective treatment for ED for men who have been assessed by a healthcare professional. It does not increase physical desire or arousal on its own — physical stimulation is still required. It must be used responsibly, at the correct dose, with awareness of health status and drug interactions. Sildenafil is a phosphodiesterase‑type 5 (PDE5) inhibitor: by blocking PDE5 it helps increase levels of cyclic guanosine monophosphate (cGMP) in the penile tissue during physical stimulation. The result is relaxation of smooth muscle in the blood vessels of the penis, improved blood flow, and therefore an erection when aroused.
