Filitra is a prescription medicine used to treat erectile dysfunction (ED) in adult men. It contains Vardenafil, a drug that improves blood flow to the penis during sexual stimulation, helping achieve and maintain an erection. Vardenafil in Filitra works by blocking the enzyme Phosphodiesterase type 5. This enzyme normally breaks down cGMP, a chemical responsible for relaxing smooth muscles in blood vessels. When PDE5 is inhibited, cGMP levels increase, causing blood vessels in the penile area to relax and widen. This improves blood flow during sexual arousal and supports a stronger erection. https://www.genericday.com/filitra-20-mg.html
