Naltrexone: Effective Treatment for Opiate Dependency

Naltrexone helps patients overcome urges to abuse opiates by blocking the drugs' euphoric effects. Generally, patients respond well with it, however, the oral formulation, which is the only one available to date, has drawbacks. Naltrexone must be taken daily, and a patient whose cravings become overwhelming can obtain opiate euphoria simply by skipping a dose before resuming abuse.

Naltrexone is a long-acting synthetic opioid antagonist with few side effects. An opioid antagonist blocks opioids from binding to their receptors and therefore it prevents an addicted individual from feeling the effects associated with opioid use. Naltrexone as a treatment for opioid addiction is usually prescribed in an outpatient medical setting, although initiation of the treatment often begins after medical detoxification in a residential setting.

The theory behind this treatment is that the repeated absence of the desired effects and the perceived futility of using the opioid will gradually diminish opioid cravings and addiction. Naltrexone itself has no subjective effects (that is, a person does not perceive any particular drug effects) or potential for abuse, and it is not addictive. However, patient noncompliance is a common problem. Therefore, a favorable treatment outcome requires an accompanying positive therapeutic relationship, effective counseling or therapy, and careful monitoring of medication compliance. Many experienced clinicians have found naltrexone best suited for highly motivated, recently detoxified patients who desire total abstinence because of external circumstances. Professionals, parolees, probationers, and prisoners in work-release status exemplify this group.

Naltrexone Treatment for Alcoholism

Naltrexone blocks opioid receptors that are involved in the rewarding effects of drinking and the craving for alcohol. It reduces relapse to heavy drinking, defined as four or more drinks per day for women and five or more for men. Naltrexone cuts relapse risk during the first 3 months by about 36 percent but is less effective in helping patients maintain abstinence.

Acamprosate

Considerable evidence supports the efficacy of acamprosate in the treatment of alcohol use disorders (AUDs). Numerous European trials have found acamprosate significantly more effective than placebo in reducing drinking days, increasing complete abstinence, and lengthening time to relapse.

Studies have found that acamprosate increased the continuous abstinence rate and doubled continuous abstinence duration compared with placebo. Similarly, a review of clinical trials concluded that acamprosate is more effective than placebo in the short and long term. Acamprosate is superior to placebo only when controlling patient characteristics associated with treatment efficacy. They also found acamprosate superior to placebo for a subgroup of patients motivated to achieve total abstinence.

Also Known as Campral

Acamprosate, Campral , is a drug used for treating alcohol dependency. Acamprosate is thought to stabilize the chemical balance in the brain that would otherwise be disrupted by alcoholism.

Acamprosate, Campral® acts on the gamma-aminobutyric acid (GABA) and Glutamate Neurotransmitter Systems and is thought to reduce symptoms of protracted withdrawal, such as insomnia, anxiety, restlessness, and dysphasia. Acamprosate has been shown to help dependent drinkers maintain abstinence for several weeks to months, and it may be more effective in patients with severe dependence.

Acamprosate is used along with counseling and social support to help people who have stopped drinking large amounts of alcohol (alcoholism) to avoid drinking alcohol again. Drinking alcohol for a long time changes the way the brain works. Acamprosate works by helping the brains of people who have drunk large amounts of alcohol to work normally again. Acamprosate does not prevent the withdrawal symptoms that people may experience when they stop drinking alcohol. Acamprosate has not been shown to work in people who have not stopped drinking alcohol or in people who drink large amounts of alcohol and also overuse or abuse other substances such as street drugs or prescription medications.

Acamprosate affects chemicals in the brain that may become unbalanced in a person who is addicted to alcohol. Acamprosate works by restoring this chemical balance in the brain in an alcohol-dependent person who has recently quit drinking.

Acamprosate is used to help a person who has recently quit drinking alcohol continue to choose not to drink (remain abstinent from alcohol). It is used together with behavior modification and counseling support to help you stop drinking.
