Although it's been used since the 1980s, naltrexone remains a relatively unknown treatment for alcohol dependency.
Costing about £3 a pill, the drug blocks the "euphoric and sedative effects" of alcohol, helping "reduce cravings" and cutting down consumption, according to London's The Standard. Naltrexone reportedly has a claimed 80% success rate in clinical trials and can be prescribed by the NHS, but is more commonly accessed privately.
But some argue that the drug should also be used to treat heavy drinkers who do not meet the "criteria for alcohol addiction", to help stop them "mindlessly" drinking, which can lead to dependency, said Esther Walker in The Times.
In a first-person account of using naltrexone in The Telegraph, Annabel Fenwick Elliott said it had been "game-changing" and "severed" the "neurological bond" that she had with alcohol.
Why, then, is it not more readily available to people wanting to reduce alcohol intake? The answer is "tangled up in red tape". The drug is "out of patent" and therefore there is "no real money to be made by Big Pharma", while in the UK it is "tricky for GPs to prescribe thanks to licensing" issues.
There is also a sense that the government doesn't want to "prioritise alcohol reduction", added Walker. At the same time, National Institute for Health and Care Excellence guidelines advise prescribing naltrexone only "alongside a programme of abstinence" that will not "sever the link in the mind between the alcohol and the dopamine reward". |
