The analysis looked at acamprosate (Campral) and naltrexone (ReVia),Reuters reports. The medications may be helpful for people in different stages of recovery, because they have different effects on the brain, the researchers report in the journal Addiction.
The researchers looked at 64 trials of the two drugs, which included a total of 11,000 people. They found acamprosate was better at helping people who were not current drinkers stay sober, while naltrexone was more effective in helping people cut back on heavy drinking and avoid cravings.
Both drugs were more effective when used after participants had not been drinking for at least a few days before starting treatment, or had been through a detox program, the article noted.
