Filitra 40 mg is a medication primarily used to treat erectile dysfunction (ED) in men. It contains the active ingredient vardenafil, which belongs to a class of drugs known as phosphodiesterase type 5 (PDE5) inhibitors. Vardenafil works by increasing blood flow to the penis during sexual stimulation, thereby helping to achieve and maintain an erection. It does this by inhibiting the action of the enzyme PDE5, which is responsible for regulating blood flow in the penis. https://www.flatmeds.com/product/filitra-40-mg/
