Vilitra 40 mg is marketed as a medicine containing vardenafil, a phosphodiesterase type-5 (PDE5) inhibitor used to treat erectile dysfunction (ED) in adult men. Vardenafil works by increasing blood flow to the penis during sexual stimulation, which can help a man achieve and maintain an erection. It does not increase sexual desire and does not produce an erection without sexual stimulation. However, 40 mg is above the usual maximum recommended vardenafil dose for erectile dysfunction.
