Best known as Viagra, the erectile dysfunction drug Sildenafil started off as a treatment for reduced blood flow but soon saw its value spike after its other effects became clear.The blue pill could have more uses, according to research by scientists at the Weizmann Institute of Science in Tel Aviv. The team found indications that it curbs cancer metastasis via a “newly discovered biological mechanism” drawing upon the drug’s blood dilatation effects.Sildenafil curbs the capacity of cancer cells to make use of cholesterol, which the team describes as “an essential component of cellular membranes”.

Scientists at the Weizmann Institute of Science in Tel Aviv have discovered that sildenafil, commonly known as Viagra, may help curb cancer metastasis. This research builds on the drug's known effects of blood dilatation. The team found that sildenafil hinders cancer cells' ability to utilize cholesterol, which is crucial for their cellular membranes. This newly identified biological mechanism suggests a potential new application for the drug beyond its original use for reduced blood flow and erectile dysfunction.
