Vilitra is a medication used for the treatment of erectile dysfunction (ED) in men. It contains vardenafil as its active ingredient. Vardenafil is a phosphodiesterase type 5 (PDE-5) inhibitor, similar to sildenafil citrate, and it works by increasing blood flow to the penis during sexual stimulation, aiding in the achievement and maintenance of an erection. The medication is typically taken orally with a glass of water, approximately 25 to 60 minutes before sexual activity.
