What is Naltrexone?
Naltrexone is a prescription medication designed to treat alcohol use disorder (AUD) and opioid use disorder (OUD). It helps reduce cravings and manage physical dependence on these substances. By blocking the effects of alcohol and opioids, naltrexone prevents the feelings of euphoria and intoxication associated with their use, thereby diminishing the urge to consume them.
For individuals struggling with alcohol use disorder, naltrexone can help decrease drinking behaviors and prevent relapses over time, leading to a reduction in cravings for alcohol. In the context of opioid use disorder, it effectively blocks the euphoric effects of opioids such as heroin, morphine, and codeine, aiding individuals in maintaining abstinence and avoiding relapse.
Low-dose naltrexone (LDN) is sometimes used off-label for conditions like fibromyalgia, Crohn’s disease, multiple sclerosis, and complex regional pain syndrome, where it may act as an anti-inflammatory agent within the central nervous system. However, it’s important to note that this use is not FDA-approved.
Naltrexone is available in two forms: as an intramuscular injection (marketed as Vivitrol) and as oral tablets. While the branded versions (Revia, Depade) have been discontinued, generic options remain accessible.
As an opioid antagonist, naltrexone primarily functions by blocking the mu-opioid receptor. Additionally, it influences the interaction of the hypothalamus, pituitary gland, and adrenal gland (the hypothalamic-pituitary-adrenal axis, or HPA axis) to help regulate alcohol consumption.
What is Naltrexone Used For?
Naltrexone is a prescription medication that is FDA-approved for two main purposes:
- Treatment of Alcohol Dependence: Naltrexone helps individuals reduce their alcohol consumption and avoid relapses.
- Opioid Dependence: It blocks the effects of opioids, preventing the feelings of euphoria associated with their use. Naltrexone is used to help individuals remain opioid-free after completing detoxification.
Before starting naltrexone, it is essential to stop drinking alcohol or using opioids. To avoid the risk of precipitated opioid withdrawal, individuals should maintain an opioid-free interval of at least 7 to 10 days if they were previously dependent on short-acting opioids. Those transitioning from medications like buprenorphine or methadone may be susceptible to withdrawal symptoms for up to two weeks.
It’s important to note that the use of low-dose naltrexone (LDN) for other conditions is not FDA-approved.
Mechanism of Action
Naltrexone functions as an opioid antagonist. It blocks the mu-opioid receptors in the brain, preventing the feelings of euphoria associated with opioid use. In terms of alcohol consumption, naltrexone can also help diminish the pleasure derived from drinking, which can lead to reduced drinking behavior over time.
Is 25 mg Naltrexone Effective?
The effectiveness of 25 mg naltrexone can vary depending on the individual and the condition being treated. While the standard dose for treating alcohol use disorder and opioid use disorder is typically 50 mg, some healthcare providers may start patients on a lower dose, such as 25 mg, to assess tolerance and minimize side effects.
Effectiveness in Different Contexts:
- Alcohol Use Disorder: Some studies suggest that lower doses of naltrexone, including 25 mg, can still be effective in reducing alcohol cravings and consumption, although higher doses may offer more significant benefits for some individuals.
- Opioid Use Disorder: For individuals recovering from opioid dependence, 25 mg might not provide the full blockade needed against opioid effects, particularly for those with a history of heavy opioid use. A minimum of 50 mg is often recommended for optimal effectiveness.
- Low-Dose Naltrexone (LDN): In some cases, 25 mg is considered a low-dose approach, which some patients use off-label for various conditions. However, research on the efficacy of LDN for conditions like fibromyalgia or Crohn’s disease is still emerging.
