With increasing ETOH use what is the first and most sensitive liver enzyme to elevate?
What is the most reliable bio marker for recent ETOH use?
CDT (carbohydrate deficient transferrin) will detect ETOH use > 60 g ETOH/day. Has a high specificity and high sensitivity for recent alcohol use. Since it is unavailable at most hospitals and outpatient treatment settings, it is often recommended that clinicians use combinations of other approaches to assess for alcohol use. CDT is a biomarker for chronic alcohol intake of more than 60 g ethanol/day. It is based on the fact that an averaged daily consumption of more than 60g of alcohol (about 5 standard drinks) during the previous 2 weeks increases the percentage of transferrin that has deficient carbohydrate content. Data show that a 30% reduction in CDT is consistent with a substantial reduction in alcohol intake. A positive % CDT test result is 1.7% or higher and may change up or down with increased or decreased drinking.

Which drugs are currently approved to treat alcohol dependence?
The first medication approved for the treatment of Alcohol Dependence was disulfiram in 1949, as an aversive medication. In 1994, oral naltrexone, an opioid antagonist that decreases the reinforcing effects of alcohol, was approved in a dosage of 50 mg/day. In 2004, acamprosate, (likely) a GABA receptor agonist and NMDA receptor modulator, was approved in a dosage of 666 mg three times a day (total dose of 1998 mg/day). In 2006, a monthly, long-acting, injectable naltrexone formulation of 380 mg/month was approved by the FDA.
What are the pharmacogenomics of alcoholism?
The primary pathway of ethanol metabolism involves oxidation by alcohol dehydrogenase (ADH) to acetaldehyde. The acetaldehyde is then further oxidized by aldehyde dehydrogenase (ALDH) to acetate, which is either excreted in the urine or reincorporated into intermediary metabolism as acetyl-CoA to begin fatty acid synthesis. Acetaldehyde buildup is toxic and causes flushing and palpitations. The ALDh2*2 allele has a prevalence of between 12% and 41% in East Asia. People who carry one copy of the inactive allele are strongly protected against alcoholism (odds ratio 0.5 to 0.12), and homozygotes are almost completely protected. (Hurley TD, Edenberg HJ. Genes encoding enzymes involved in ethanol metabolism. Alcohol Res 2012;334(3):339–344.)

In 1994, it was approved as a Schedule II treatment drug for narcotic addiction. Both methadone and LAAM have high abuse potential. Their acceptability as narcotic treatment drugs is predicated on their ability to substitute for heroin, the long duration of action, and their mode of oral administration.

What test confirms thiamine deficiency?
Meconium drug screening/testing reflects maternal drug use from what time frame?
2nd trimester forward
What is the mortality associated with DTs?

Which isoenzynes mediates conversation of codeine to morphine?
Which region of the brain mediates withdrawal?
Tramadol is a pro-drug that must be converted to the M1 metabolite. It's a weak mu. Increases serotonin release and thus possible serotonin syndrome. Causes seizures both in taking and in withdrawal.
What is the half life of methadone?
How long for methadone to reach steady state?
What is the minimal desirable blood level for methadone?
Where is buprenorphine derived from?
What is the mechanism of action of clonidine in the treatment of opioid withdrawal?
Clonidine acts in the locus ceruleus to decrease NE; thus decreases autonomia. But does not do much for myalgias/arthralgias
Compare naltrexone to naloxone
Naltrexone has a longer half-life (av= 4 hrs);
Active metabolite (6 beta-naltrexol, mean half life= 13 hours);
Greater affinity for kappa receptor.
50 mg naltrexone will block the pharmacological effects of 25 mg IV heroin for up to 24 hrs
Name 2 alpha adrenergic non-opioid agonists used to treat autonomic symptoms during opioid withdrawal.
Lofexidine has less hypotension than does clonidine.
What is the dose of clonidine to treat symptoms of nor-adrenergic hyperactivity?
0.1 to 0.2 mg clonidine every 4 hours, up to 1.2 mg per 24 hrs with careful BP monitoring
Why has LAAM been withdrawn?
Torsades de pointe
What is the ratio of buprenorphine to naloxone in Suboxone?
How is methadone metabolized?
Hepatic via CYP 450 3A4 enzymes
What are the two most studied and best characterized endocannabinoids?
Anandamide and 2-arachidonalglycerol (2-AG)
Which endogenous neurotransmitters are affected by benzodiazepines and GHB
GHB-----> GABA B
What is the volume of distribution for nicotine?
What is the half-life of nicotine?
What is the metabolism of nicotine?
Metabolized to cotinine in brain, liver and lung via CYP 2A6.
Chinese have slower CYP 2A6 alleles.
Which gender metabolizes nicotine faster?
What are the bio markers for nicotine replacement modalities?
How long does plasma cotinine persist?
Up to 7 days
What cotinine level indicates smoking?
> 14 ng/mL;
100 ng/mL indicates 1/2 pack per day use
What CO level indicates smoking within past 8-12 hours?
10 ppm CO
Smoking accelerates metabolism of drugs metabolized by which CYP?
What characterizes nicotine withdrawal?
Craving, irritability, anger, anxiety, depression, difficulty concentrating, restlessness, increased appetite. Symptoms reach max intensity 24-48 hrs after cessation.
Which nicotine receptors are responsible for dependence?
What mediates nicotine withdrawal?
Alpha-5 containing nAChRs in the habenula produce nicotine's aversive effects and the somatic symptoms of withdrawal.
What are the pregnancy related smoking risks?
Double the risk for LBW infant;
30% inc risk for spontaneous abortion and peri and neonatal mortality.
The effect of smoking in LBW is influenced by the metabolic genes CYP 1A1 and GSTT1.
What is the half life of cotinine?
18-30 hours and reflects exposure over 2-3 days
Which marker can distinguish abstinent tobacco users who are using NRT from those still using tobacco?
What is the mechanism of action of varenicline?
Partial agonist/antagonist that selectively binds to the alpha-4 beta- nicotinic acetylcholine receptor.
It acts to block both nicotine from binding to the receptor (antagonist effect) and stimulate (agonist effect) receptor mediated activity leading to the release of dopamine which reduces craving and nicotine withdrawal symptoms.
What are the most frequent adverse effects of varenicline?
Nausea; vivid dreams
Neuropsychiatric effects (suicidal thoughts and aggressive or erratic behavior)
What is the only absolute contraindication to varenicline?
What is the effect of adding pharmacotherapy to a behavioral intervention in smoking cessation?
Doubles abstinence rates
What are the drug-drug interactions between varenicline and bupropion for smoking cessation?
There are none as they have different mechanisms of action
Which is more efficacious;bupropion or varenicline?
Varenicline is but it is not superior to NRT
What are the adverse effects of topiramate used for alcohol use disorder?
Parenthesis, taste perversion, anorexia, difficulty with concentration/attention, nervousness, dizziness, pruritus, psychomotor slowing, weight loss
Which medications show the best results in alcohol use disorder?
Acamprosate and naltrexone but neither is superior
What is the availability of injectable naltrexone and acamprosate in the VA system?
These are non-formulary for the VA system
What are the averse effects of acamprosate?
Anxiety, diarrhea, vomiting
