Q

What do Antagonist and agonist drugs do?

A

Common treatment is medication
- drugs work at the level of this synapse to alter behaviour
- act on specific biological processes
- either mimic or block the effects of particular substances on the brain

Q

Evaluation effectiveness: Substitution drugs
X Comparing methadone to buprenorphine

A

B- milder medication, both agonist and antagonist properties
Ag- partially activated the D receptors, reducing withdrawal symptoms
Ant- blocks the receptors, preventing euphoria associated with opioids
B- much reduced chance of overdose
- ceiling effect, taking larger quantities will not produce a greater effect

Q

Evaluation effectiveness: Substitution drugs
X Naltrexone, NICE

Study These Flashcards
A

Nice reviewed17 studies concerning effectiveness of naltrexone for heroine addiction
x found conflicting results
x many of randomised control trials showed no significant difference between N and control treatment for retention
-N associated with reduction in relapse rates, highly motivated Ps, where they are closely monitored and offered support

22
Q

Evaluation effectiveness: Substitution drugs
- Naltrexone, Lahti

Study These Flashcards
A

Tested effectiveness of N on a small sample of gamblers, instructed to take N before gambling or when they felt the urge to
- significant decrease in gambling levels
X further research needed with placebo for comparison

23
Q

Evaluation effectiveness: Substitution drugs
X Naltrexone, Gowing

Study These Flashcards
A

NOT appropriate for all drug users
x completely stopped taking heroine as withdrawal symptoms may occur
x right attitude towards recovery, highly motivated to quit
x not as useful on those less motivated

24
Q

Evaluation effectiveness: Substitution drugs
X Attrition rates

Study These Flashcards
A

Drop outs are not reflected in the final results
x only show it works for those who are still in the study
x highly motivated to quit
x those not will have dropped out, may not have worked for them

25
Evaluation Ethical: Substitution drugs Side effects
Confusion, dizziness, nausea, tremors, seizures
26
Evaluation Ethical: Substitution drugs Side effects X dangers of methadone
May interact with other drugs - alcohol and antidepressants = respiratory problems - danger of overdose 2023- 709 deaths - struggle to make detoxification and abstinence, on for 20+ year - transfer addiction, unethical
27
Evaluation Ethical: Substitution drugs Side effects X Risks of Naltrexone
Monitor liver function x if opioid dependant, withdrawal symptoms x displace opioids still in system from receptors
28
Evaluation Social: Social Implications X social problems
x strain on NHS x waiting times A n E, doctors x impact on police x high crime and unemployment rates x less tax money collected x more claims on universal credit
29
Evaluation Social: Social Implications Social effect of methadone - The National treatment agency
Treating heroine users with methadone has an immediate positive effect on society by reducing their criminality - rates of offending half when they are in treatment
30
Evaluation Social: Social Implications Social effect of methadone X Gynell
Drug-relating reoffending has continued to rise despite methadone
31
Evaluation Social: Social Implications Findings from Advisory Council of drug misuse
Those in poorer areas receive less help and due to deprivation are more likely to engage in drug use from an earlier age
32
Evaluation Social: Social Implications Cost effectiveness of methadone X Gynell
Prescribing methadone was an expensive failure and costs society money, not just for methadone but for 320,000 problem drug users on benefits
33
Evaluation Social: Social Implications Cost effectiveness of methadone - Doward
Charity DrugScope has disputed claims saying that the report overestimated the cost of prescribing methadone - is cost effective
34
What is the 2nd method of modifying?
Aversion therapy
35
What are the key principles of aversion therapy?
- principle of classical conditioning - associate addiction with unpleasant stimulus - unpleasant response rather than pleasure - no longer deriving pleasure- they stop taking substance/engaging in behaviour > practical, ethical, safety- only used for alcohol
36
What drug is used in aversion therapy?
Antabuse (disalfiram)
37
How does Antabuse (disulfiram) work?
Drug Antabuse acts as a aversive (unconditioned) stimulus - affects how the body metabolizes alcohol - causes a disulfiram reaction, stops enzyme from working - leads to a build up of toxins in the bloodstream
38
What does Antabuse cause and how does this modify addiction?
Range of unpleasant symptoms - sweating, heart palpitations, headaches, vomiting - occurs within 10 minutes of consuming alcohol and can last for hours - once association has been made, the person will try and avoid contact with behaviour and triggers associated with the addiction e.g. pubs
39
Classical conditioning schedule for Antabuse
Before : UCS - UCR (Antabuse) (sickness) NS (alcohol) - nothing During: NS + UCS - UCR (alcohol) (Antabuse) (sickness) After: CS - CR (alcohol) (avoidance)
40
What do NICE guidelines suggest about Antabuse?
- begin after individual has undergone withdrawal - daily dose of 200mg, increased if the reaction to alcohol is not aversive enough - remain under supervision every 2 weeks for the first 2 months then monthly for the next 4 months - must be careful about alcohol in other substances such as food or mouthwash, may contain enough alcohol to cause an unpleasant reaction
41
What is Rapid smoking?
A second, less common form of aversion therapy, there is no additional medication required
42
How does Rapid smoking work?
Smokers sit in a closed room and take a puff on a cigarette every 6 seconds until they finish a specific number of cigarettes or feel sick - US is not a drug, something unpleasant - intensive smoking creates UCR of feeling disgust or sick - associate unpleasant feeling with smoking and develop an aversion for it - repeated over several sessions to make it stronger
43
Evaluation effectiveness: Aversion Therapy - Research for Antabuse
STAFFEN - compared Antabuse to placebo and found a significantly greater abstinence duration than the placebo group - shows effective, increases validity Jorgensen - found that people treated with A had more days until relapse and fewer drinking days - external reliability (consistency)
44
How can we Criticise research for Antabuse?
X no long-term studies X lack scientific rigour X not full randomised controlled trials X few comparisons between A and other treatments for alcoholism X often take place on small samples X hard to carry out placebo studies as patients will be aware which condition the are in if they drink and no adverse effects are experienced
45
Evaluation effectiveness: Aversion Therapy - Research for Rapid Smoking
McRobbie cessation clinic, 100 smokers, control watched video about giving up - RS showed a significant decrease in urge to smoke in 24hrs/week after procedure X at 4 weeks the difference between groups were no longer significant, impact of RS on long-term abstinence remains unclear - reducing urge in early period may be useful in kick-starting the process and then other techniques can be employed
46
Evaluation: Aversion Therapy X Practical issues
X limited research as it is less popular now X does not tackle the root causes- not remove bigger issues X only treats the behaviour, not the underlying cause X aversion remains, underlying problem (cog bias) not addressed X may switch the focus of their addiction- gambling
47
Evaluation Ethics: Aversion Therapy X Side effects
X long term health problems from RS X lung damage, increased risk of cancer X rash, nausea, headaches, unpleasant - addicts cannot be legally forced to undergo AT, voluntarily, choice and free will
48
Evaluation Ethics: Aversion Therapy X Antabuse implants
Insert into lower abdomen- George Best died X drank again not long after the implants were fitted X lack of research on long term effects X not available on the NHS X interferes with the right to withdraw
49
Evaluation Ethics: Aversion Therapy - Covert sensitisation
Encouraged to imagine feelings of being sick and vomiting when they have the urge to drink KRAFT- series of case studies highlighting that although this technique is not common, it is quick and effective
50
Evaluation: Aversion therapy X social implications
Both smoking and drinking cost the UK economy a lot of money X any treatment that is able to reduce the rates of these addictions may also be able to prevent lot the harm caused, my be able to save money
51
Evaluation Social: Aversion therapy X Devlin
Dramatic increase on spending on Antabuse/other drugs to treat alcoholism 2008 NHS- £2.25mil 1998 NHS- £1.08mil
52
Evaluation Social: Aversion therapy - Alcohol concern
Small amount compared with the money spent on treating alcoholism and related problems on NHS - investing in treatment and prevention saves NHS more in the long run
