Fildena 120 mg is a medication used to treat erectile dysfunction (ED) in men. It contains sildenafil citrate, which is the same active ingredient as in other ED treatments like Viagra. Sildenafil citrate, the active ingredient, works by inhibiting the enzyme phosphodiesterase type 5 (PDE5). This results in increased levels of cyclic GMP, leading to relaxation of the smooth muscles in the blood vessels of the penis and improved blood flow, which helps produce an erection.
