Filitra is a medication used to treat erectile dysfunction (ED) in men. The active ingredient in Filitra is vardenafil, which is the same active ingredient found in Levitra. Vardenafil belongs to a class of drugs known as PDE5 inhibitors, which work by increasing blood flow to the pill, helping men with ED achieve and maintain an erection during physical activity. Filitra works by inhibiting the phosphodiesterase type 5 (PDE5) enzyme, which is responsible for restricting blood flow in the pill. https://www.genericday.com/filitra-20-mg.html
