Why does naltrexone help for alcoholism?
While the precise mechanism of action for naltrexone’s effect is unknown, reports from successfully treated patients suggest three kinds of effects. First, naltrexone can reduce craving, which is the urge or desire to drink. Second, naltrexone helps patients remain abstinent. Third, naltrexone can interfere with the tendency to want to drink more if a recovering patient slips and has a drink.
