Filitra is a prescription medicine used to treat erectile dysfunction (ED) in adult men. It contains vardenafil, which helps improve blood flow to the penis during sexual stimulation. This enzyme normally restricts blood flow in the penile arteries. When it is blocked, the blood vessels relax and widen, allowing more blood to flow into the penis during sexual arousal. This helps achieve and maintain a firm erection. It does not increase sexual desire and requires sexual stimulation to work.
