Vilitra is a medication used for the treatment of erectile dysfunction (ED) in men. It contains the active ingredient vardenafil, which is a phosphodiesterase type 5 (PDE5) inhibitor. Vardenafil works by increasing blood flow to the penile during physical stimulation, facilitating the ability to achieve and maintain an erection. Vardenafil is known for its relatively rapid onset of action. It may start working within 30 minutes to an hour after ingestion, though the onset time can vary among individuals. https://www.genericday.com/vilitra-20-mg.html
