Low-dose naltrexone

Low-dose naltrexone (often abbreviated as LDN) is a low-dose formulation of naltrexone that is used off-label for the treatment of various conditions.

Overview

Naltrexone is a medication that was originally approved by the FDA for the treatment of opioid addiction and alcoholism. In low doses, however, it has been found to have immunomodulatory effects and is used off-label for a variety of conditions, including chronic pain, autoimmune diseases, and cancer.

Mechanism of Action

The exact mechanism of action of low-dose naltrexone is not fully understood. It is believed to work by temporarily blocking the opioid receptors in the brain, which leads to an increase in the production of endorphins. These endorphins play a role in pain relief, immune system regulation, and cell growth.

Uses

Low-dose naltrexone has been used off-label for a variety of conditions, including:

• Chronic pain
• Fibromyalgia
• Multiple sclerosis
• Crohn's disease
• Cancer

Side Effects

Research

While there is some preliminary evidence supporting the use of low-dose naltrexone for certain conditions, more research is needed to fully understand its effectiveness and safety.
