Our Philadelphia ED drug skin cancer lawyers are evaluating cases involving patients who developed (or experienced worsening) malignant melanoma after using erectile dysfunction (ED) drugs, or PDE-5 inhibitors.

PDE-5 inhibitor ED drugs linked to melanoma (the most dangerous type of skin cancer) include:

  • Cialis
  • Levitra
  • Staxyn
  • Stendra
  • Viagra

PDE-5 inhibitors treat erectile dysfunction (ED) by relaxing blood vessels, thereby increasing blood flow to the penis. The blood vessel relaxation is accomplished by a blocking / inhibiting of the enzyme Phosphodiesterase-5, or PDE-5. Blockage of the enzyme increases the risk of developing melanoma, however, and may also make an existing cancer more aggressive.
