Fildena 120 is a widely used medication designed to treat erectile dysfunction (ED) in men. It contains Sildenafil Citrate, the same active ingredient found in Viagra. Sildenafil is classified as a PDE5 inhibitor, and it works by blocking the enzyme phosphodiesterase type 5 (PDE5).

By inhibiting PDE5, Sildenafil helps increase levels of cyclic guanosine monophosphate (cGMP) in the body, which relaxes the smooth muscles in the blood vessels of the penis.

The recommended dosage of Fildena 120 is typically used for men who need a higher dose to manage more severe erectile dysfunction. It is usually prescribed when lower doses of Sildenafil are not effective.

Men should take the medication 30 to 60 minutes before sexual activity, allowing it enough time to be absorbed into the bloodstream and take effect.

The duration of action for Fildena can last between 4 to 6 hours, providing a window of opportunity for sexual activity.

However, it is important to note that Fildena 120, like all PDE5 inhibitors, requires sexual stimulation to be effective. Without arousal, the medication will not cause an automatic erection.
