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:
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.
Studies Linking ED Drugs to Melanoma
Several studies have linked use of ED drugs / PDE-5 inhibitors with an increased risk of developing or worsening melanoma.
- A Harvard study published in a 2014 issue of the Journal of the American Medical Association (JAMA) found an 84% increased risk of developing malignant melanoma in Viagra (sildenafil) users.
- A study published in the January 2011 issue of Cancer Cell showed an increased risk of melanoma progression / invasiveness with PDE-5 inhibitor use.
- A study published in an August 2012 issue of Journal of Cell Biochemistry linked Levitra (vardenafil) use with an increased risk of developing melanoma.
- Study results discussed in April and July 2017 issues of the journal Oncotarget linked ED drug use with an increased risk of malignant melanoma.
- Results from five studies reported in the September 2017 issue of the Journal of the American Academy of Dermatology showed an association between ED drug use and an increased risk of developing melanoma.
ED Drug Skin Cancer Lawsuits
Philadelphia ED drug skin cancer lawyers representing clients who experienced development or worsening of melanoma after using PDE-5 inhibitors may allege that ED drug manufacturers:
- designed and made drugs that significantly increased users’ risks of developing and worsening melanoma
- failed to adequately warn consumers and physicians of the increased risks of melanoma development and exacerbation with PDE-5 inhibitor use
