Zudena 100 mg Tablet is a medicine that treats erectile dysfunction (ED) in males. It promotes sexual desire by relaxing the muscles in the penile blood vessels. This improved circulation promotes a powerful and pleasurable erection, to revitalize ED patients' sexual experiences. It works by inhibiting the PDE-5 enzyme, causing higher cGMP levels in penile tissues. Please keep in mind that Zudena 100 mg Tablets only help you have an erection when you're sexually aroused. It does not generate sexual desire by itself.
