Filitra 40 mg is a medication used to treat erectile dysfunction (ED). It contains vardenafil as its active ingredient, which is similar to sildenafil (Viagra) and tadalafil (Cialis) in that it helps increase blood flow to the penis to assist in achieving and maintaining an erection during sexual activity. The typical starting dose is 40 mg, taken about 1 hour before sexual activity. The dose can be adjusted based on effectiveness and tolerance, but it should not exceed 80 mg per day. https://www.flatmeds.com/product/filitra-40-mg/
