Zudena 100 mg is a medication used to treat erectile dysfunction (ED) in men. The active ingredient in Zudena is Udenafil, a PDE5 inhibitor similar to other ED medications like Sildenafil (Viagra), Tadalafil (Cialis), and Vardenafil (Levitra). It works by increasing blood flow to the penis, helping men with ED achieve and maintain an erection during sexual activity.
