Fildena:

Fildena is a medication primarily used to treat erectile dysfunction (ED) in men. It contains Sildenafil Citrate, the same active ingredient found in Viagra. This is a PDE5 inhibitor that works by increasing blood flow to the penis during sexual stimulation, helping to achieve and maintain an erection. Fildena works by blocking the enzyme PDE5, which normally breaks down cGMP, a molecule that helps relax the muscles and blood vessels in the penis.
