Filitra 40 mg is a medication used to treat erectile dysfunction (ED) in men. It contains vardenafil as its active ingredient, which is a phosphodiesterase type 5 (PDE5) inhibitor. Like other PDE5 inhibitors such as sildenafil (Viagra) and tadalafil (Cialis), vardenafil works by increasing blood flow to the penis during sexual stimulation, facilitating the ability to achieve and maintain an erection.
