Fildena is a medication used to treat erectile dysfunction (ED), a condition where a man has difficulty achieving or maintaining an erection sufficient for sexual activity. It contains the active ingredient sildenafil citrate, which belongs to a class of medications called phosphodiesterase type 5 (PDE5) inhibitors.
Here's how Fildena 100 works: When a man is sexually stimulated, the body releases nitric oxide in the erectile tissue of the penis. Nitric oxide then activates an enzyme called guanylate cyclase, which leads to an increase in levels of cyclic guanosine monophosphate (cGMP). This cGMP relaxes the smooth muscles in the blood vessels of the penis, allowing them to dilate and increase blood flow into the penis, resulting in an erection.
