Melanoma Skin Cancer Side Effect Associated With Erectile Dysfunction (ED) Drugs Cialis, Levitra, Viagra, Staxyn, And Stendra, As Well As PAH Medications Revatio And Adcirca
According to an April 2014 medical journal article,
Viagra (sildenafil), the most popular and well-known drug prescribed for male erectile dysfunction (ED), appears to
increase the risk for malignant melanoma — but not other skin cancers like cutaneous squamous cell carcinomas nor basal cell carcinomas.
The four other brand name ED drugs that are phosphodiesterase 5 (PDE5) inhibitors,
Cialis(tadalafil),
Levitra (vardenafil),
Staxyn(vardenafil), and
Stendra (avanafil) are probably associated with an increased risk of melanoma skin cancer, too.
Cialis is also prescribed sometimes when doctors see the signs and symptoms of benign prostatic hyperplasia (BPH).
Two other phosphodiesterase 5 (PDE5) inhibitors are
Revatio (sildenafil) and
Adcirca(tadalafil). These drugs are prescribed for the treatment of pulmonary arterial hypertension (PAH).
Essentially, the active ingredients sildenafil, tadalifil, vardenafil, and avanafil which are found in these ED, BPH, and PAH drugs act by inhibiting the phosphodiesterase 5 (PDE5). Experimental in vitro studies show that PDE5 inhibition augments tumor cell invasiveness. In turn, this effect seems related to an apparent
melanoma skin cancer side effect for all of the brand name drugs with these active ingredients:
- Sildenafil: Viagra and Revatio
- Tadalafil: Cialis and Adcirca
- Vardenafil: Levitra and Staxyn
- Avanafil: Stendra
The recent medical study finding which indicates an association between each of these PDE5 inhibitor drugs with invasive melanoma skin cancer might be of particular concern to patients that have used any of these drugs and who may be at an elevated risk of melanoma due to a history of:
- extensive sun exposure;
- basal or squamous cell skin cancers;
- Parkinson disease (which causes autonomic erectile dysfunction and is associated with elevated risk of melanoma); or,
- other family members diagnosed with melanoma.
We are currently investigating cases of melanoma in men who used Viagra, Cialis, Levitra, Staxyn, or Stendra as well as men and women who used Revatio or Adcirca, as possible drug injury lawsuits against the responsible pharmaceutical companies. For example:
Levitra – Melanoma – 62 yr old man
Cialis – Melanoma – 60 yr old man
Cialis – Malignant Melanomas (three) – 64 yr old man
Cialis – Melanoma Skin Cancer – 55 yr old man
Viagra / Cialis – Melanoma – 48 yr old man
Viagra – Melanoma – 45 yr old man
Cialis – Malignant Melanoma – 39 yr old man
Cialis – Malignant Melanoma – 60 yr old man
Cialis – Melanoma – 60 yr old man
Cialis – Metastasized Melanoma – 67 yr old man
