Alcohol addiction remains a pervasive issue, affecting millions worldwide. According to the National Institute on Alcohol Abuse and Alcoholism, 29.5 million Americans aged 12 and above were diagnosed with Alcohol Use Disorder (AUD) in 2022, which is about 10.5% of that age group.

Alcohol use disorder can be detrimental to both mental and physical health and often worsens overall quality of life. People who are trapped in a cycle of addiction find it difficult to safely stop drinking and there is a risk for severe if not fatal withdrawal for some if they try to quit cold turkey. Additionally, many struggle with relapse due to long term withdrawal symptoms and cravings.

Therefore, as efforts to safeguard public safety are enhanced, recognizing effective treatment options is crucial. In this regard, one of the most effective solutions is complementing therapy and behavioral interventions with medications. 

If you’re looking to overcome AUD or help someone do so, keep reading. This article will explore how the medication Acamprosate can help with alcohol addiction recovery.

What is Acamprosate?

Facts about Acamprosate for alcohol addiction

Acamprosate, commonly known by its brand name Campral, is a medication used to reduce cravings for alcohol and reduce risk for relapse. It functions by stabilizing the chemical balance in the brain disrupted by chronic alcohol consumption. 

Typically prescribed in tablet form, Acamprosate is taken orally and works by modulating neurotransmitter activity, specifically gamma-aminobutyric acid (GABA) and glutamate. Since it works on similar neurotransmitters to alcohol, it is safest to be used after someone has detoxed for those who struggle with daily drinking and should only be used for individuals who want to maintain abstinence as opposed to those looking to just moderate their drinking.

As per data from the National Library of Medicine, you can reduce the chances of returning to any drink by 86% by receiving Acamprosate. It’s an extremely effective medication and has helped many people recover and remain stable in their sobriety.

Benefits of Alcohol Addiction Recovery

Acamprosate offers several benefits in alcohol addiction recovery. For starters, it restores the balance of neurotransmitters in the brain, helping reduce the unpleasant symptoms associated with post acute alcohol withdrawal, such as anxiety, restlessness, and insomnia. 

Additionally, Acamprosate aids in minimizing alcohol cravings, which are common triggers for relapse during the recovery process. As part of a comprehensive treatment plan, Acamprosate can significantly enhance the success rate of individuals striving to overcome alcohol addiction and maintain sobriety.

Who Can Take Acamprosate?

Acamprosate is suitable for individuals with alcohol use disorder, particularly those committed to maintaining sobriety. Since this medication does not prevent alcohol withdrawal, many who drink daily require inpatient or outpatient detox before starting it using a different medication to prevent and reduce severe withdrawal symptoms. Once someone is able to safely achieve abstinence for at least a few days in a row, they can begin treatment with Acamprosate.

Acamprosate does not metabolize through the liver, so anyone with liver issues related to drinking can safely take this medication. Caution is advised for people who have kidney issues and for pregnant individuals since kidney function affects the efficacy and safety of taking Acamprosate and there are no studies showing that it is safe in pregnancy. Additionally, patients taking other medications should consult with their healthcare provider to assess potential interactions. 

But despite these considerations, Acamprosate remains a valuable option for many individuals seeking adequate support in their journey towards alcohol addiction recovery.

Acamprosate vs Naltrexone

Quick facts about Naltrexone or Vivitrol for addiction treatment

Both Acamprosate and naltrexone are medications commonly used in the treatment of alcoholism and are considered first-line treatments, yet they differ in their mechanisms of action and therapeutic effects.

Acamprosate works by stabilizing the chemical balance in the brain that is disrupted by chronic alcohol consumption. It reduces the unpleasant symptoms of long term alcohol withdrawal symptoms and helps to restore normal brain function, thereby reducing the urge to drink.

On the other hand, Naltrexone operates by blocking opioid receptors in the brain. Alcohol acts on opioid receptors by increasing feelings of comfort and reducing pain and anxiety. Taking naltrexone can help reduce the rewarding effects of alcohol, making it less desirable and reinforcing.

Naltrexone is metabolized by the liver so individuals with liver concerns may lean towards trying Acamprosate first since it doesn’t affect the liver. Additionally, individuals with kidney concerns may lean towards trying naltrexone since it doesn’t affect kidney function. Another distinction is that naltrexone dosing is just one pill a day while Acamprosate requires two pills taken three times a day to be effective, so individuals who struggle to remember to take medications throughout the day may do better with naltrexone. Finally, Acamprosate is not safe to take while still drinking but naltrexone is so individuals looking to just moderate over choosing sobriety should try out naltrexone over Acamprosate.

Despite their distinct mechanisms of action, both medications share a common goal of aiding individuals in maintaining sobriety and preventing relapse. The choice between the two medications may depend on individual factors such as medical history, treatment goals, individual preference and response to previous therapies. Consulting with a healthcare professional is essential in determining the most suitable treatment approach for each individual.

Acamprosate vs Antabuse (Disulfiram)

Quick facts about Disulfiram for alcoholism

While both Acamprosate and Antabuse (disulfiram) are medications used in the treatment of alcohol addiction, they differ in their mechanisms of action and therapeutic effects.

As stated previously, Acamprosate functions by modulating neurotransmitter activity in the brain, reducing cravings and the desire to drink alcohol. In contrast, Antabuse works by blocking the enzyme involved in metabolizing alcohol, leading to the accumulation of acetaldehyde, a toxic substance. When alcohol is consumed while taking Antabuse, it results in extremely unpleasant symptoms such as nausea, vomiting, fast heart rate, sweating and facial flushing. This aversive reaction serves as a deterrent to drinking alcohol.

Antabuse is not considered a first-line treatment option due to reaction that can occur if alcohol is consumed on it. However, many find the accountability of Antabuse more beneficial and it’s still widely used to prevent relapses on alcohol. Therefore, the choice between the two medications depends on individual preferences, treatment goals, and medical history, with healthcare professionals guiding the decision-making process.
