The scientific journal The Prostate just published research on a new potential anticancer agent found through repurposing of phentolamine. Phentolamine is an alpha blocker; when given by injection, it causes blood vessels to expand, thereby increasing blood flow. It is used commercially to treat hypertension and erectile dysfunction under the names OraVerse and Regitine in the United States. This study suggests phentolamine could be a viable option in treating some forms of cancer. Future research in optimizing its effects is needed.
