Zhewitra 20 mg is a medication used to treat erectile dysfunction (ED) in men. It contains vardenafil, which belongs to the same class of drugs as sildenafil and tadalafil. Vardenafil works by relaxing blood vessels and improving blood flow to the penis during sexual stimulation. This helps a man achieve and maintain an erection, but only when he is sexually aroused—it does not increase sexual desire on its own.
