During 2020, I heard of  the drug Ivermectin for the first time in my life. I had come across it mentioned in an article online where it was reported that veterinary medication was showing promise as an anti-cancer agent. Certain cancers in particular were responding well and research was underway in tumor suppression. Later that year Ivermectin again came to my attention when reports surfaced that it was a remarkable cure for Covid. I was fascinated and hooked. A drug created for parasite treatment in pets was also found to be useful in treating Corona Virus, colds, flus and cancer is as unlikely sounding a story as can be imagined.

Naturally that development led me to begin reading more about other veterinary medications and it was in 2021 I began learning that another pet medication was reportedly showing excellent results in the treatment of Cancers and assorted tumors in human subjects. That drug is called Fenbendazole. Its prescribed for dogs! Being a farmer I actually had a bottle of it in my cabinet. But mine was for deworming cattle and sheep (although the molecule is likely identical to the dog version).

So I took a closer look at the bottle since I recalled it was a blended product with another medication. I was unfamiliar with the second medication. It is called Rafoxanide. And would you not know it but after doing a little digging I came across a recent research article published at the National Institute of Health (NIH) reporting the current discovery of Rafoxanide as a novel agent for the treatment of lung cancer (NSCLC). Promising research as it turns out although its still in the early stages of testing. Here is the conclusion from that paper:

In the present study, we found that rafoxanide can inhibit NSCLC cell growth and migration, and
induce cell ERs. The UPR and autophagy were activated to eliminate the ERs, however, excessive
ERs could induce cell apoptosis. Additionally, a xenograft mouse model was used to determine
the effect of rafoxanide treatment on NSCLC, the results indicated that rafoxanide significantly
suppressed the NSCLC tumor growth in vivo. Collectively, these findings indicated that rafox-
anide might be a potential anti-cancer drug for NSCLC.

Rafoxanide markedly decreases the growth and inhibits the invasion and migration of NSCLC cells.

Wow! Of course I had to pass this along to those of you who are also interested in why these anthelmintic (anti-parasite) drugs keep coming up roses where cancer is concerned. And curious minds want to know….are cancers really parasite infestations? Your guess is as good as mine.  You will have to do your own follow up on this story of course. I am certainly not suggesting anyone take this stuff. In fact I would strongly advise against it. I am not a Doctor and I have no medical training. Like you I am simply someone who reads a lot online and just found this to be a fascinating development. Very little information is currently available on human use of this drug. So this story is breaking. But you may want to keep the name on your radar as research progresses because maybe….just maybe, it has a future.
