Zhewitra is a medication used to treat erectile dysfunction (ED) in men. The active ingredient in Zhewitra is Vardenafil, which belongs to the class of drugs known as PDE5 inhibitors. It works by increasing blood flow to the penis to help a man achieve and maintain an erection during sexual stimulation. Vardenafil, similar to Sildenafil (in Viagra) and Tadalafil (in Cialis), helps treat erectile dysfunction by inhibiting the enzyme phosphodiesterase type 5 (PDE5). https://www.flatmeds.com/product/zhewitra-20-mg/
