Behav 2 Pharm Flashcards
Dementia
Ok
Central ache inhibitors
Tacrine, donepezil, rivastigmine, galantamine, memantine,
Tacrine
• High incidence of hepatotoxicity, newer agents are preferred (no longer used clinically
Addiction vs physical dependency
Physical dependence and tolerance are normal physiologic adaptations
-cant diagnose addiction
Addiction-primary chronic disease of brain reward, motivation, memory and related circuitry so get biological, psychological and behavioral dysfunction
Tolerance and physiological dependence , pain relief ,
Misinterpreted as drug seeking or relapse behavior
Reward defiency syndrome
Dopamine system malfunction
Common pathway for addictive behavior
Addiction genetic
Yes but also environmental
Non substance specific
Addictophrenia model
Assess disease risk severity
Type I alcoholism-mean Nd women need genetic and env predisposition later in life, mild or severe
Type II-sons of male alcoholics, genetic not env, start adolescence , associated with criminal
Addictophrenia type I
Genetic history of addictive disorder-alc
Genetic history of mood disorder
Higher incidence of comorbid mood disorder
Type Ii
Genetic history of addictive disorder-mixed substance and non
Genetic history of personality disorder or criminal behavior
Higher incidence of criminal behavior, risk taking and gambling
Type II
Genetic history of addictive disorder-not a prerequisite, but increases vulnerability
Significant history of trauma-predominantly alchol and benzodiazepine use
Addictophrenia type IV
Genetic history of addictive disorder-not prerequisite but increases vulnerability
Chronic use of high dose drugs known to cause severe physical dependency
High associated with presence of severe psychosocial stressors
Diagnose addictophrenia
Overlaps
Rate scal one to ten one ach category
Predict degree of susceptibility and assist in counseling and treatment planning
Validity and reliability has not been tested
Do ppl die when addicted
Yes. Fifty percent have comorbid psychiatric disorder
-antisocial PD, depression, suicide
Substance use disorder
Using larger amounts for longer
Desire or unsuccessful attempts to cut down or control use
Great deal of time obtaining, using or recovering
Crave, cant fulfill roles, social and interpersonal problems
Stop doing things , tolerance, withdrawal, physical hazard situations
Mild substance use
Two to three symptoms
Moderate substance use
Four to five symptoms
Severe substance use
Six or more symptoms
Early remission
No criteria except craving for over three months but less than twelve
Sustained remission
No criteria for over twelve months except craving
What is substance abuse mental disorder
Symptom of mental disorder
How identify substance abuse mental disorder
Developed one month of substance intoxication or withdraw of med
Involved the substance/med is capable of producing the mental disorder
Not better explained by independent mental disorder (preceded substance, mental disorder stay long after substance gone one month)
Not only in delirium
Distress
Intoxication doe snot apply to what
Tobacco
What has no withdrawal
PCP, inhalants, hallucinogens
Neuroadaptation
CNS changes following repeated use such that person develops tolerance and/or withdrawal
-
Pharmacokinetic neuroadaptation
Adaptation of metabolizing system
Pharmacodynamic neuroadaptation
Ability of cns to function despite high blood levels
Tolerance
Increase amount to get effect or decrease effect same amount
Hospital for withdrawa
Overdose, severe , , suicide, medical comorbidities
Residential withdrawal
No monitoring, restricted env, partial hospitalization
Outpatient withdrawal
No risk and highly motivated
Motivational interventions for withdrawal
Family, relapse prevention, twelve step, alcohol anonymous, CBT< narcotics anonymous
Do a lot of ppl have more than one psychiatric disorder
Yes. Fifty percent
Alcohol intoxication level
.08
Fatal if get to airway issue and cns depression, pulmonary aspiration
Early alcohol withdrawal
Anxiety, irritability, htn, hyperthermia, tachycardia, nausea
Seizures alcohol withdrawal
Twenty four to fort with
Delirium tremendous
Forty eight to seventy two
Three to ten days after
Agitation, confusion, disoriented, fever, HTN, diaphoresis, autonomic hyperactive ,
Hallucinations, autonomic instability, life threatening
Hallmark of delirium tremendous
Profound global confusion
Chronic intake alcohol
Increased opiates, activate GABA A producing GABA inhibition, influx cl, impregnate NMDA which mediates glutamate and interacts with serotonin and dopamine receptors
Withdrawal alcohol
Loss gaba a receptor stimulation causes reduce cl cause tremors, diaphoresis, tachycardia, anxiety, seizures,
Inhibits NMDA receptos
Seizures, delirium
CIWA
Numerical value to symptoms with points
> ten severe withdrawal
Treat withdrawal alcohol
Benzodiazepines GABA agonist
Anticonvulsants for seizure risk -carbamazepine or valproic acid
Thiamine supp
Meds for staying off alc
Disulfiram, naltrexone, acamprosate
Disulfiram
No work more harm than good
Inhibits aldehyde DH
Can cause death if alcohol given
Psychiatric AE, dermatological rashes, polyneuropathy, hepatotoxicity
Naltrexone
Opioid antagonist
Check LFT
Acamprosate
Unknown moa check kidney function
Benzodiazepine
Similar to alc but less cognitive impaired
More lipophilic shorted action
Withdrawal benzodiazepines
Similar to alcohol can get from tapering too fast
Sconvert short to long half life then slowly taper
Decrease does every week or two
If rapid give valproic acid or carbamazepine
Or gabapentin and tizanidine
Opioid intoxication
Pinpoint pupils, constipation, bradycardia, hypotension, decreased rr
Withdrawal opioids
Not life threatening unless severe medical illlness but uncomfortable, dilated pupils lacrimation, goosebumps, nv
Treat opioid with
Anti-emetic, antacids, NSAIDS< BZd
Treat
Support education, skills, methadone, naltrexone, buprenorphine
Methadone
From methadone assisted treatment program
Oral
High risk deadly when used with benzodiazepine, or 3a4 substrate
Mu agonist
What do if not MAT and in er for pain
Call service at methadone clinic then give dose
If need mroe dont use another 3a4 substrate
Naltrexone
Opioid blocker, mu antagonist
Buprenorphine
Partial mu agonist
Need to take ASAM course to give prescription
If highly motivated
Stimulate acute intox
Euphorias, vigor, gregariousness, hyperactivity, restlessness, interpersonal sensitivity, anxiety tension, anger, impaired judgement,
