Project gamma – MOBE - mobile behaviour

It markedly attenuates or completely blocks, reversibly, the subjective effects of exogenous opioids. A significant naltrexone × OPRM1 genotype interaction was observed for intensity of demand. The present study extends the literature on naltrexone's mechanisms through the application of a novel behavioral economic paradigm. These results indicate that naltrexone reduces several indices of demand for alcohol. 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.

2016] Naltrexone does this by primarily blocking mu-opiate receptor occupancy and thereby reducing the amount of dopamine released from the nucleus accumbens The mechanism of action of naltrexone in alcoholism is not understood; however, involvement of the endogenous opioid system is suggested by preclinical data. Naltrexone is thought to act as a competitive antagonist at mc, κ, and δ receptors in the CNS, with the highest affintiy for the μ receptor. Although the precise mechanism of action for naltrexone’s effect is unknown, reports from successfully treated patients suggest the following three kinds of effects: Naltrexone can reduce a patient’s urge or desire to drink. Naltrexone helps patients remain abstinent.

Naltrexone is a type of medication known as an opiate antagonist (or opioidergic agent). These medications ‘block’ cells in the brain that would normally respond to chemicals called opiates. Opiates often give people a big ‘high’ or a ‘rush’ and boost their feelings of wellbeing. 2011-09-02 Mechanism of Action. Opioid competitive receptor antagonist; shows highest affinity for mu receptors; congener of oxymorphone.

It is capable of antagonizing all opiate receptors. Its action is similar to naloxone except that it is longer acting and administered orally.
