Naltrexone is an opioid antagonist that was first approved by the U.S. Food and Drug Administration (FDA) in 1984 for the treatment of opioid dependence. In 1994, based on emerging clinical evidence, it was also approved for the treatment of alcohol dependence. Since then, it has been widely used as part of a comprehensive treatment plan for people seeking to reduce alcohol consumption and regain control over their drinking behavior.

Many people want to drink less or drug addiction treatment regain control without being forced into complete abstinence. The Sinclair Method (TSM) is a medical approach used as a treatment for alcohol use disorders, including alcohol dependence and related conditions. It offers a new way to address alcoholism and problem drinking by using targeted naltrexone, a prescription medication that blocks the pleasurable feelings linked to drinking alcohol. Instead of requiring people to stop drinking completely, this treatment method helps reduce alcohol consumption over time through a scientific process known as operant conditioning. This method has been shown to be more effective than many other alcohol treatment programs, especially when compared to abstinence-based models, which require immediate and total sobriety. The Sinclair Method (TSM) offers a novel way of treatment for Alcohol Use Disorder (AUD) that, in many ways, opposes traditional methods like 12-step programs.

Naltrexone will cause a precipitated withdrawal in patients taking opiate drugs or heroin. Symptoms of opiate withdrawal such as nausea, vomiting, bone and joint pain, chills, fever, etc will be similar but more severe than normally experienced in withdrawal without naltrexone. “My patients who are members of the Thrive find it an encouraging and useful source of peer support and information.

Keep a drinking diary or log, noting the date/time, whether you took the medication beforehand, how much you drank, and how you felt afterwards. Over weeks and months, you’ll want to look for patterns like less pleasure from drinking, not craving as much the next day, or drinking feels more optional. The ‘naltrexone before drinking’ rule is non-negotiable if you want the extinction‐based mechanism to work. That means planning ahead, ensuring you have the medication on hand, and sticking to the schedule even if you’re out socially.
Medication-assisted treatment for reduction of drinking (naltrexone). Critics argue that the Sinclair Method is only successful with monitoring alcoholism. Some also argue that people with alcohol problems may not hold themselves accountable for taking Naltrexone when they want to drink. Consult your doctor about whether or not the Sinclair Method to eliminate alcohol addiction will be safe or likely effective for Sinclair method you. 📌 Stigma around medication-assisted treatment – Some people still believe overcoming alcohol use disorder should happen without medication, even though research shows otherwise. ❗ Commitment is key – Skipping doses or not taking naltrexone consistently before drinking can make TSM less effective.
With the endorphin release caused by alcohol effectively blocked, you won’t experience a buzz. He also discovered that administering naltrexone before drinking would eventually extinguish the drinking behavior. Later research also demonstrated that naltrexone had a similar effect on humans with alcohol use disorder who wanted to drink less. While Naltrexone is safe for most people, it may cause mild side effects like nausea or dizziness. A healthcare provider can assess your medical history to determine if it’s suitable for you.
Do Rehab Centers Endorse the Sinclair Method?
If you or someone you know is grappling with alcohol addiction, the Sinclair Method could be the key to regaining control and achieving a healthier, happier life. Remember, seeking help is the first step towards recovery, and with the Sinclair Method, a solution may be within reach. When individuals consume alcohol while on naltrexone, they experience diminished pleasure, which can lead to a decrease in overall consumption over time.
- It needs to be used correctly and consistently in order for it to be effective.
- In order for the Sinclair Method to be successful, it is important to always, without fail, take naltrexone before consuming any alcohol.
- While the Sinclair Method primarily focuses on pharmacological intervention through naltrexone, integrating behavioral therapy can significantly enhance its effectiveness.
- In 1994, after discovering that the drug could prevent alcohol cravings and inhibit alcohol’s effects, the FDA approved it for treating alcohol use disorder.
- If someone on naltrexone needs surgery or pain meds, they’ll need alternatives.
Skipping the medication on drinking days undermines the extinction effect, allowing the brain to receive endorphin rewards from alcohol. Conversely, taking naltrexone on non-drinking days is not strictly required by TSM, though some do so if they suspect an unplanned event might involve alcohol. Over repeated sessions, the pleasurable or relieving feeling from alcohol is diminished, leading to less interest in drinking at all.
Naltrexone has high affinity for the mu opioid peptide receptor (MOP-R) with moderate activity at the delta opioid peptide receptor (DOP-R) and kappa opioid peptide receptor (KOP-R). Preclinical studies suggest that the MOP-R plays a significant role in ethanol-mediated behaviors, however, there is evidence suggesting the DOP-R may be a better therapeutic target for treating AUDs. This chapter will review studies investigating the role of the opioid receptors in ethanol-mediated behaviors with the view of identifying improved therapeutics for the treatment of AUDs. The Sinclair Method aims to break this cycle through pharmacological extinction. By taking naltrexone before drinking, the medication blocks the opioid receptors, preventing endorphins from binding and reducing the pleasurable effects of alcohol.
