These neurons are under tonic inhibition by GABA-ergic interneurons within VTA. The first thing to understand is that naltrexone – the drug in LDN – comes in a 50:50 mixture of 2 different shapes (called isomers). It has been recently discovered that one particular shape binds to immune cells, whilst the other shape binds to opioid receptors. Mechanism of Action. Naltrexone (a pure opioid antagonist) is a cyclopropyl derivative of oxymorphone similar in structure to naloxone and nalorphine (a morphine derivative); it acts as a competitive antagonist at opioid receptor sites, showing the highest affinity for mu receptors.

It is capable of antagonizing all opiate receptors. Its action is similar to naloxone except that it is longer acting and administered orally. MECHANISMS OF ACTION Naltrexone is pharmacologically different from opioids, and as such, naltrexone is not associated with tolerance or dependence.
