Fildena 120 mg is a medication used primarily to treat erectile dysfunction (ED) in men. It contains sildenafil citrate, a phosphodiesterase type 5 (PDE5) inhibitor, which helps increase blood flow to the penis, facilitating an erection when sexually aroused. Sildenafil citrate inhibits the enzyme PDE5, which leads to increased levels of cyclic guanosine monophosphate (cGMP). This results in relaxation of the smooth muscles in the blood vessels of the penis, allowing for increased blood flow and an erection. https://www.flatmeds.com/product/fildena-120-mg/
