3.1.5 Agonist & Antagonist Evaluation (Add) Flashcards
(agonist) NICE assessed 31 reviews into the effectiveness of methadone including what?
27 randomised controlled trials
(agonist - methadone) what is a randomised controlled trial?
one group is allocated to placebo and one experimental, who ends up where is random
(agonist - methadone) NICE found higher levels of what of those using methadone compared to placebo?
higher levels of retention
(agonist - methadone) NICE found lower levels of what of those using methadone compared to placebo?
lower levels of opiod use
(agonist - methadone) NICE research suggests what about the effectiveness of methadone?
more effective than placebo in stopping opiod usage
(agonist) a 2006 meta analysis of studies into effectiveness found methadone is effective as long as dosage is what?
adequate
(agonist - methadone) what is a meta analysis?
gathering of all existing data e.g. on a treatment and analysing it
(agonist) what is buprenorphine?
milder alternative to methadone
(agonist) what properties does buprenorphine have?
agonist and antagonist
(agonist) explain what is means that buprenorphine had both agonist and antagonist properties?
it can bind to a receptor and imitate the action of a substance but it can also block the action of a substance
(agonist - methadone) a study analysing data from over 5 years concluded buprenorphine is how many times safer than methadone?
6x
(agonist - methadone) why is buprenorphine safer than methadone?
ceiling effect - less risk of overdose
once a certain amount has been taken increasing dosage has no further effect
(agonist - methadone) even though buprenorphine is safer why is methadone the preferred treatment?
allows for dosage to be increased to a point where no withdrawal symptoms are seen
even at the ceiling effect of buprenorphine withdrawal symptoms may be seen
(antagonist - naltrexone) NICE reviewed how many studies concerning the effectiveness of naltrexone for heroin addiction?
17
(antagonist - naltrexone) what did NICE find in their review of studies into effectiveness of naltrexone?
no difference between naltrexone and control treatments for retention on treatment programmes
(antagonist - naltrexone) what does NICE research suggest about naltrexone?
no more effective in treating addiction than other treatments
(antagonist - naltrexone) in NICEs research naltrexone was associated with a reduction in what?
relapse rates
(antagonist - naltrexone) NICE found naltrexone was associated with a reduction in relapse rates particularly in patients who were what?
highly motivated
closely monitored
offered extra support
(antagonist - naltrexone) NICEs findings on naltrexone and reduced relapse rates suggest what?
naltrexone is effective in preventing relapse particularly when other support is made available
