The National Institute for Clinical Excellence (NICE) in the UK has the final say on what drugs are given away for free via the National Health Service (NHS).
In June 2010 they published a draft 500-page report – that included references to 27 research experiments on naltrexone.
http://www.nice.org.uk/nicemedia/live/11875/49448/49448.pdfHowever, it didn't mention the Sinclair Method - and the conclusions are not aligned with the thinking of this group.
I read the most of the report. Chapter 7 is the relevant one for us:
Pharmacological interventions for treatment and management of alcohol misuse - Page 338 to 413.
There are some great quotes:
Naltrexone saves healthcare system £83,432 per patient over a 20-year period.
Alcohol increases levels of endorphins or opiates in the brain, but there is increasing evidence that drugs that block the opioid neurotransmitters, such as naltrexone, can reduce the reinforcing or pleasurable properties of alcohol and so reduce relapse in alcohol dependent patient s (Anton, 2008).
The comparison of oral naltrexone versus placebo showed a small but significant effect favouring naltrexone on rates of relapse to heavy drinking But worryingly this is the conclusion (page 375):
"When using naltrexone for relapse prevention, patients should be abstinent."The report mistakenly recommends that naltrexone be prescribed on a daily basis. Here are the prescribing guidelines - page 396:
If using oral naltrexone, start treatment after assisted withdrawal and typically prescribe at a dose of 50 mg per day.
Provide the service user with an information card about oral naltrexone and its impact on opioid-based analgesics, as part of a comprehensive medical assessment before prescribing. Oral naltrexone should:
• Typically be prescribed for up to 12 months, or longer for those benefiting from the drug who want to continue with it
• Be stopped if drinking persists 4–6 weeks after starting the drug.The report is an excellent source of information but concludes:
Some doctors can be reluctant to prescribe pharmacological interventions such as naltrexone, due to lack of knowledge or familiarity. Barriers to prescribing naltrexone have been described as including a ‘lack of awareness, a lack of evidence of efficacy in practice, side effects, time for patient management, a reluctance to take medications, medication addiction concerns, Alcoholics Anonymous (AA) philosophy, and price.So due to a "due to lack of knowledge or familiarity" doctors are not prescribing Nal... and those that do prescribe it to ensure abstinence rather than control.
