Vilitra is a medication used to treat erectile dysfunction (ED) in men. Its active ingredient is Vardenafil, which works by increasing blood flow to the penis, helping men achieve and maintain an erection when sexually aroused. Vilitra works by inhibiting the enzyme PDE5, which allows blood vessels in the penis to relax and expand. This increases blood flow, which is necessary for an erection. Like other ED medications, it typically starts working within 30 to 60 minutes and lasts for around 4-5 hours.
