MAR vs MAT vs MOUD: What’s the Difference?

The terms Medication-Assisted Treatment (MAT), Medication-Assisted Recovery (MAR), and Medication for Opioid Use Disorder (MOUD) are all used to refer to substance addiction treatment. However, whilst these terms are often used interchangeably, SAMHSA has recently started recommending replacing MAT and MAR with MOUD, as they do have slightly different connotations and carry different meanings when it comes to addiction treatment plans.

Understanding the difference between MAT, MAR, and MOUD is important so you know what your treatment team means when they use these terms and can make informed decisions about your recovery options.

Key Takeaways on MAT/ MAR/ MOUD:

• MAR and MOUD are relatively new terms, often used interchangeably with MAT to describe substance abuse treatment, although they have different implications and meanings.
• MAT refers to medication used to treat substance abuse disorder, along with counseling and therapy.
• MAR also refers to medically assisted recovery from substance abuse disorder, to be used alongside other therapies and treatment services.
• MOUD refers to FDA-approved medications as a stand-alone treatment for opioid use disorder.
• The key reason for the new terms is to destigmatize the connotations of MAT – medication-assisted treatment and (in the case of MOUD) stress the power and efficiency of medication alone.
• MAT, MAR, and MOUD medications include methadone, buprenorphine, and naltrexone.
• Staff at Revive Treatment Centers’ methadone programs are available to discuss the differences between MAT, MAR, and MOUD with addicts and advise them which treatment model would work best for them.

What Is MOUD?

MOUD means medications for opioid use disorder, which refers to specific FDA-approved medications used to treat opioid use disorders (OUD). MOUD focuses solely on medication as an effective stand-alone treatment for OUD, even without other forms of counselling.

What Is MAT?

MAT stands for medication-assisted treatment, a holistic approach that combines medication with behavioural therapies and counselling to treat substance use disorders, including opioid and alcohol use disorders.

What Is MAR?

MAR stands for medically assisted recovery and is a new name for MAT. This is intended to reduce the stigma of medical treatment associated with recovery.

MAT and MAR view addiction as a long-term medical condition needing both clinical care and therapeutic support. MAT/MAR helps patients tackle their cravings and withdrawal symptoms while simultaneously working through the emotional and behavioural components of addiction, usually at addiction programs. It involves:

• Counseling and behavioral therapies that work on the emotional and psychological roots of addiction
• Medications, such as methadone treatment, that help stabilize brain function and ease withdrawal
• Additional support services, like case management and peer recovery programs, to help sustain long-term recovery

MAT/MAR/MOUD: Why the Name Difference?

The terminology is shifting from MAT to MAR and MOUD to reduce stigma. The word “recovery” helps to highlight the recovery process as the major aspect of the treatment, not the medication. The old term “assisted” makes it seem like the medication is just a backup, replacing one drug with another, so the term MOUD was added to refer to cases where medication is the main part of the treatment.

In addition, the term MOUD addresses a common misconception that medication is only effective with counseling and other therapy techniques. Research shows that these medications are powerful, effective tools on their own. The new name, MOUD treatment, reflects their true role: medication is a primary and effective treatment for OUD, not a secondary add-on.

MAR and MAT vs MOUD: Key Differences

The following table highlights the key differences between the two terms:

Feature	MAT/MAR	MOUD
Definition	An integrated approach that combines medication, counselling and therapies to treat substance addictions.	The use of FDA-approved medication to treat opioid addiction.
Used for	Used to treat various substance use disorders, such as opioid use disorder (OUD) and alcohol use disorder (AUD).	Specifically used to treat opioid use disorder (OUD).
Implication	The term “assisted” can contribute to stigma, suggesting that patients using medication are not in “true” recovery or are substituting one addiction for another.	Aims to destigmatize treatment by framing it as a standard medical intervention for a psychiatric disorder, moving away from language that implies a failing.
Treatment model	Medication works in conjunction with behavioural therapies and support services.	Using medication as a stand-alone treatment.

What Is MOUD Treatment?

MOUD treatment uses FDA-approved medications – methadone, buprenorphine, and naltrexone – to treat opioid use disorder by reducing cravings, preventing withdrawal, and lowering overdose risk by up to 50%.

FDA-Approved Medications for a MAR or MOUD Program

The three FDA-approved medications for MAT/MAR/MOUD programs, methadone, buprenorphine, and naltrexone, work in slightly different ways and are available in different forms.

Methadone for Relief From Cravings

Methadone works by tricking the brain into thinking it is still getting the drugs the person was previously using. It is an agonist medication that binds to and fills the opioid receptors in the brain.

This provides relief from cravings and withdrawal symptoms. Methadone is taken daily and is available in a pill, liquid, or powder form. It is only available at specially licensed treatment centers, due to its potential for misuse. Some people must go to the treatment centers daily to take their medication, but people who are stable in their recovery become eligible for a prescription to take at home.

Buprenorphine for MOUD Treatment

Buprenorphine (suboxone) is a partial agonist medication that activates the opioid receptors in the brain to a lesser degree than methadone. This also reduces cravings and withdrawal symptoms without having a euphoric effect. Buprenorphine is taken daily at first, but eventually, it may be taken only every other day. It is available in a pill form. There is also an extended-release injection option, which is taken monthly. Because it has a lower risk of misuse, it is available at treatment centers and by doctors who have special approval to prescribe suboxone. Some people go in to receive their medication, whilst others can be prescribed medication to take at home.

Naltrexone, Used After Detox

Naltrexone (vivitrol) employs a different tactic to help overcome addiction. It is an antagonist medication, which blocks the opioid receptors in the brain, so if the individual tries to use opioids again, they won’t have any effect. This medication also has no euphoric effects, making it effective for relapse prevention but not for managing withdrawal symptoms. It is available in a pill form, to be taken daily, and as an extended-release injection, to be administered monthly.

A key point to keep in mind is that people need to be off opioids for a certain amount of time before beginning naltrexone. If it’s taken too early, it can trigger rapid, intense withdrawal, making the start of treatment more difficult. For this reason, naltrexone is typically used for individuals who have already detoxed from opioids and want a non-opioid medication to support long-term recovery.

Successful MAR Saves Lives

The success of medication-assisted recovery has been documented. When MAR services are provided in primary care, there is a 50% decrease in illicit opioid usage.

MAR has also been found to reduce the mortality rate of patients with OUD by half. This refers to overdose deaths from opioid usage and all other death rates in patients.
