Filitra 40 is a medication primarily used for the treatment of erectile dysfunction (ED), a condition where a man struggles to achieve or maintain an erection suitable for sexual activity. Filitra 40 contains the active ingredient vardenafil, which belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. It works by increasing blood flow to the penis during sexual stimulation, thus helping to achieve and sustain an erection.
