Filitra 40 mg is a medication used to treat erectile dysfunction (ED) in men. Its active ingredient is vardenafil, which is a phosphodiesterase type 5 (PDE5) inhibitor. Like other PDE5 inhibitors, Filitra works by increasing blood flow to the pill during physical stimulation, helping to achieve and maintain an erection. By inhibiting the PDE5 enzyme, Filitra helps to relax the blood vessels in the pill, allowing for increased blood flow. https://www.genericday.com/filitra-40-mg.html
