14 Mechanism of action edit Naltrexone and its active metabolite 6-naltrexol are antagonists at the -opioid receptor (MOR the -opioid receptor (KOR) to a lesser extent, and to a far lesser and possibly insignificant extent, at the -opioid receptor (DOR).16 The blockade of opioid receptors is the basis behind naltrexone's action in the management of opioid dependenceit reversibly blocks or attenuates the effects of opioids. Its mechanism of action in alcohol dependence is not fully understood, but as an opioid receptor antagonist is likely.
Similarly one will not show normal response to opioid pain medications when taking naltrexone. In a supervised medical setting pain relief is possible but may require higher than usual doses, and the individual should be closely monitored for respiratory depression.12 A 2009 study of naltrexone as an alcohol dependence treatment among African Americans failed to find any statistically significant differences between naltrexone and a placebo. 13 Studies have suggested that carriers of the G allele may experience higher levels of craving and stronger "high".
