How Much Do You Know About Low-Dose Naltrexone (LDN)?
I was fascinated to watch this interview with Professor Angus Dalgleish and to learn the remarkable story behind low-dose naltrexone (LDN).
Like many repurposed medicines, LDN began life with a completely different purpose. In the 1980s, Dr. Bernard Bihari was using naltrexone to help patients recovering from heroin and morphine addiction. As he reduced their doses, many patients asked to remain on a much lower dose because they noticed unexpected improvements in conditions such as multiple sclerosis, Crohn’s disease, arthritis, and other autoimmune or inflammatory disorders.
The most important part of the story? He listened to his patients.
Rather than dismissing what they were telling him, Dr. Bihari worked with colleagues to investigate why these effects might be occurring. This led to research suggesting that low-dose naltrexone temporarily blocks opioid receptors, triggering biological responses that may influence both the immune and endocrine systems.
Professor Dalgleish became interested after one of his own oncology patients experienced unexpectedly positive results while being treated with Dr. Bihari. Curious, he travelled to meet Dr. Bihari and better understand both the drug and its proposed mechanisms.
Professor Dalgleish then began offering LDN to patients with advanced cancers who had exhausted conventional treatment options. He noticed that some patients continued returning for repeat prescriptions, prompting him to re-scan several of them. In some cases, tumours that had been expected to progress appeared to remain stable, leading him to investigate possible mechanisms further, including the potential role of inflammatory pathways such as IL-6.
Of course we are on repeat …even with promising observational results, we are unlikely to see the large RCT needed for this cheap generic drug.
It’s another interview from one of fantastic senior fellow’s, watch it here: https://www.youtube.com/watch?v=S5Y_ShsPTpQ
