Fighting Alcoholism With Medications
Drugs combined with support can help alcoholics kick alcohol addiction.
With no enzyme to break it down, acetaldehyde builds up in the body after
even a small amount of alcohol is ingested, resulting in extremely unpleasant
side effects that can include flushing, nausea, and palpitations.
"The big limitation for a medicine like Antabuse is that what people do
instead of deciding that alcohol's a bad thing to take, they think that
Antabuse is a bad thing to take and they stop taking it," Volpicelli tells
WebMD."Antabuse doesn't take away your craving, and if you drink you still get
the effects of alcohol you would normally in terms of the pleasure, until you
reach the point where you start feeling sick."
Antabuse is most effective when its use is monitored, say in an alcoholism
clinic or at home by a spouse or family member, experts say.
Volpicelli has at least one patient who uses Antabuse as a kind of
"chaperone" when she's in social situations. When she starts to feel that her
face is flushing, she knows that she has to stop drinking or will get very
sick, he says. But for the vast majority of patients the best way to prevent
relapse is to stop drinking altogether, specialists in alcoholism treatment
Naltrexone helps to both reduce the pleasure that alcoholics receive from
drinking and the cravings that compel them to seek out more alcohol. It does so
by blocking receptors (docking sites) in the brain for endorphins, proteins
produced by the body that help to elevate mood. The same receptors also accept
narcotics such as morphine and heroin. The drug can be taken
as a once-daily pill or in a recently approved once-monthly injectable
"Naltrexone sort of gets at the core of what addiction is," Volpicelli says.
"The way I like to describe it is that addiction is a condition in which when
you do something, you want to do more and more of it. So when people have one
or two drinks, instead of stopping after a few drinks they want to have three,
four, five, 10 drinks. What we found is that naltrexone breaks that positive
feedback loop, so that people can have one or two drinks and they don't feel
like having any more."
