Fildena 100mg is an oral medication commonly prescribed for the treatment of erectile dysfunction (ED) in adult men—a condition characterized by difficulty achieving or maintaining a firm erection during sexual activity. It contains 100 milligrams of sildenafil citrate as its active ingredient, a substance belonging to a class of medications known as phosphodiesterase type 5 (PDE5) inhibitors. Sildenafil works by relaxing the smooth muscles within the blood vessels of the penis, thereby improving blood flow during sexual stimulation. This increased blood flow helps a man achieve and maintain an erection sufficient for sexual intercourse. However, Fildena 100mg does not induce sexual arousal on its own; sexual stimulation is required for the medication to be effective.
