Ketamine may reduce heavy drinkers’ craving

By Mutala Yakubu

A one-off dose of ketamine may help heavy drinkers cut back on alcohol, an experimental trial by University College London suggests.

When the sedative was used to disrupt people’s memories of why they wanted to drink, they drank less and their urge to drink lowered over nine months.

The researchers say ketamine could be a helpful treatment for alcohol and other addictions.

Experts said the findings were worthy of further investigation.

What is ketamine?
Ketamine is widely used in the NHS as an anaesthetic, sedative and pain reliever.

It is also commonly used on animals.

Because of its hallucinogenic effects, it is also thought of as a “party drug”.

But it can cause serious harm to the body, and be fatal, if used this way.

Ketamine is classed by the government as a Class-B drug, which means it is illegal to take, carry, make or sell.

Recreational use risks:

serious bladder problems
feelings of sickness
confusion
memory problems
paralysis of the muscles
hallucinations
depression
flashbacks


What did the study find?
The study involved 55 men and 35 women who were drinking about 30 pints of beer a week – five times the recommended limit – but had not been diagnosed with alcohol addiction and were receiving no treatment.

First, they were shown pictures of beer and other drinks, asked to rate their urge to drink and the pleasure it would give them and then given a beer.

Next, they were split into three groups and:

the process was repeated but instead of a beer, they were given a small dose of ketamine via an intravenous drip
the process was repeated but instead of a beer, they were given a placebo (dummy drug) via an intravenous drip
the process was not repeated and they were given a small dose of ketamine via an intravenous drip
During the following nine months, all three groups managed to reduce their drinking.

But the first group had the greatest overall improvement:

cutting their alcohol intake by about half
drinking on fewer days
when given a small beer, having less urge to drink it and enjoying it less
