“In case an alcohol-dependent patient is not able
or willing to become abstinent immediately, a
clinically significantly reduced alcohol intake with
subsequent harm reduction is also a valid,
although only intermediate, treatment goal, since
it is recognised that there is a clear medical need
in these patients as well.”

• Decreased academic performance, low mood and
difficulties with parents.
• Worried because of her sexual behaviour when
drunk.
• Wants to avoid drunkeness on weekends, but thinks
a bit of drinking is essential when meeting with
friends in order to overcome her social phobia.
30. • Mild to moderate AUD
• Socially stable
• Psychological distress (anxiety/
depression that may or may not be linked
to alcohol intake)
• Desire to reduce their drinking to avoid

35. Nalmefene – What it does!
• Nalmefene diminishes
the reinforcing effects
of alcohol, helping the
patient to reduce
drinking possibly by
modulating cortico-
mesolimbic functions.

36. Nalmefene indication
Nalmefene Summary of Product Characteristics, 2012
• Nalmefene is indicated for the reduction of alcohol consumption in adult
patients with alcohol dependence who have a high drinking risk level
(DRL), without physical withdrawal symptoms and who do not require
immediate detoxification
• Nalmefene should only be prescribed in conjunction with continuous
psychosocial support focused on treatment adherence and reducing
alcohol consumption
• Nalmefene should be initiated only in patients who continue to have a
high DRL two weeks after initial assessment

44. Avoid a confrontational approach
• Review of four decades of treatment outcome research.
• A large body of trials found no therapeutic effect of
confrontational strategies relative to control or comparison
treatment conditions.
• Several have reported harmful effects including increased
drop-out, elevated and more rapid relapse.
• This pattern is consistent across a variety of confrontational
techniques tested.
• In sum, there is not and never has been a scientific evidence
base for the use of confrontational therapies.

Review
of
the
effec;veness
of
treatment
for
alcohol
problems,
2006
Structured, motivation enhancing intervention, as opposed to just screening and
brief advice:
1. Careful History
2. Clinical Examination
3. Laboratory testing
4. Detailed and repeated review of drink diaries
5. Motivational approach
48. • AUD are a brain disease and a public health problem
• AUD are underdiagnosed (First Gap)
• Patients who do not respond to BI should be offered more
intensive treatments, including a reduction approach (Second
Gap)
• Reduction of alcohol consumption is a feasible goal with
nalmefene – efficacy is evident immediately and maintained up
to 1 year
The ‘as-needed’ dosing, and the reduction goal are well
accepted and empower the patient
• Nalmefene must be prescribed within a psychosocial support
strategy that is based on motivational principles and monitors
alcohol consumption carefully
