    Sildenafil melanoma


    SAN FRANCISCO (CBS SF) — Over 200 men who took Viagra say the drug increased their risk of developing melanoma. Now they’re suing pharmaceutical giant Pfizer Inc., claiming negligence and failure to warn them of the erectile dysfunction drug’s danger. Lawsuits against Pfizer are being filed almost daily, all claiming almost the exact same thing: that they developed melanoma after taking Viagra. But Pfizer maintains that there is no scientific evidence supporting a cause and effect relationship between the use of Viagra and the development of the deadly skin cancer, melanoma, which has long been linked to increased exposure to ultraviolet radiation. The flood of lawsuits began after the publication of a 2014 study in the Journal of American Medical Association. The study’s authors state that while they did not find that using Viagra, which also goes by its generic name sildenafil citrate, caused melanoma to develop, they found that “Sildenafil use may be associated with an increased risk of developing melanoma.” Dr. Wen-Qing Li, now a professor of dermatology and epidemiology at Brown University, is one of the main authors of the 2014 study. It had been thought the erectile dysfunction drug, Viagra, increased a man’s risk of melanoma - one of the deadliest forms of skin cancer. However new research has discovered it’s not to blame. In the study by New York University (NYU), they found an 11 per cent increased likelihood of developing melanoma in those taking erection medication, but found the drugs themselves aren’t the reason for the increased risk. They concluded that the apparent link was down to those who took drugs to treat erectile dysfunction also happening to be more health conscious, and therefore likely to see a doctor who then might spot other conditions, such as melanoma. Stacy Loeb, a urologist and assistant professor at NYU, said: “Physicians should still screen for melanoma risk, but they do not need to add the use of Viagra and similar drugs to the list of screening criteria specifically."In general, men should continue to be careful about the risk of any kind of skin cancer from excessive sun exposure and use sun protection."In the UK thousands of men are diagnosed each year, and since the 1990s melanoma skin cancer rates have increased by 162 per cent in men, compared to by 89 per cent in women. These new findings publicised in the Journal of the National Cancer Institute follow last year’s decision by the FDA to put Viagra and other erectile dysfunction drugs on its watch list of medications with possible safety issues. This decision came after a 2014 study, published in the Journal of the American Medical Association, which seemed to find a connection between Viagra use and melanoma.

    A recently published prospective cohort study reported that sildenafil use may increase the risk for melanoma JAMA Intern Med. 2014;14-970. BRAF. Viagra sildenafil is a prescription medication used to treat impotence erectile dysfunction in men. The generic version sildenafil is sold under the brand name Revatio that was initially developed for men and women and prescribed to improve exercise and treat pulmonary arterial hypertension. Viagra use has long been linked to vision and hearing problems, as well as possible heart complications. But its active ingredient, sildenafil, more.

    , Li et al found that recent and ever use of sildenafil for erectile dysfunction was associated with increased risk of subsequent melanoma, but not squamous cell or basal cell carcinoma. The RAS/RAF/MAPK and ERK kinase/ERK cascade is crucial to melanoma cell proliferation and survival. Sildenafil is a phosphodiesterase (PDE) 5A inhibitor, and recent data indicate that BRAF activation downregulates PDE5A; low PDE5A expression resulting from BRAF activation or sildenafil use increases melanoma invasiveness, raising the possibility of an effect of sildenafil on incident melanoma risk. Study Details The study involved 25,848 men in the Health Professionals’ Follow-up Study who were questioned regarding sildenafil use for erectile dysfunction in 2000. Participants who reported cancer at baseline were excluded. The incidences of melanoma, squamous cell carcinoma, and basal cell carcinoma were obtained biennially from self-reported questionnaires. Diagnosis of melanoma and squamous cell carcinoma were pathologically confirmed. Editors carefully fact-check all Drugwatch content for accuracy and quality. But its active ingredient, sildenafil, more recently has been linked to an increased risk for melanoma, the most dangerous skin cancer. Viagra use has long been linked to vision and hearing problems, as well as possible heart complications. This includes peer-reviewed medical journals, reputable media outlets, government reports, court records and interviews with qualified experts. In 2014, a study published in JAMA Internal Medicine found that sildenafil, more commonly known by its brand name Viagra, may increase a man’s likelihood of developing melanoma by as much as 84 percent, for those who reported using Viagra in the three months prior to the study’s start. The study included a total of nearly 26,000 male participants who were followed by researchers for 10 years. At its conclusion, it was found that men who reported using Viagra some time before the onset of the study were 92 percent more likely to be diagnosed with melanoma than those men who reported having never used the drug. But study co-author Wen-Qing Li said more research is needed prior to concluding that the use of Viagra causes melanoma. Abrar Qureshi said the study’s results merely point to a correlation, or link, between the two. June Robinson of Northwestern University’s Feinberg School of Medicine said doctors treating older men taking Viagra should also be checking them for signs of skin cancer.

    Behandeling van diabetes mellitus type 2 met orale bloedglucoseverlagende middelen komt pas in aanmerking indien geen goede bloedglucoseregulatie wordt bereikt met voorlichting, educatie, aanpassing van de voeding en stimulering van lichaamsbeweging. Metformine is eerste keus bij de medicamenteuze behandeling. Bij onvoldoende resultaat hiermee, kan een kortwerkend sulfonylureumderivaat (voorkeur gliclazide) worden toegevoegd. De volgende stap is (toevoeging van) insulinetherapie. De overige bloedglucoseverlagende middelen komen pas in aanmerking indien gebruik van bovenstaande voorkeursmiddelen op bezwaren stuit. Er zijn aanwijzingen dat glucagonachtige peptide-1-agonisten een neutraal tot positief effect hebben op (diabetesgerelateerde) mortaliteit en morbiditeit. Als toevoeging aan een behandeling met metformine en/of pioglitazon kan de huidige dosis van deze middelen worden voortgezet. Aan de vergoeding van exenatide zijn voorwaarden verbonden, zie Regeling zorgverzekering, bijlage 2. Bij toevoeging aan een sulfonylureumderivaat of een basale insuline, een verlaging van de dosis van deze middelen overwegen om de kans op hypoglykemie te verkleinen; hierbij kan zelfcontrole van de bloedglucosewaarde nodig zijn.
