Methadone- 3x
Heroin- 5x
Fentanyl- 50-100x
Carfentanil- 10,000x
What sxs are a/w mild doses of opioids? (6)
Pupil constriction → Nausea → Cough suppression → Pain relief → Mild sedation → Euphoria
What sxs are a/w moderate doses of opioids? (3)
Mod sedation → Memory impairment → AMS
What sxs are a/w severe/ overdose of opioids? (6)
Confusion → Respiratory depression → LOC → Apnea → Coma → Death
What opioid receptor is responsible for the greatest SEs (+ greatest dependence, least dysphoria)?
Mu receptor
Pt presents with pupillary constriction, respiratory depression, lower body temp/ BP, muscle relaxation, and stupor nodding. What are you concerned for?
Signs of abuse/ OD
Pt presents with pupillary dilation, panting/ yawning, diarrhea, elevated temp/ BP, muscle contractions, insomnia, and flu-like sxs. What are you concerned for?
Opioid acute withdrawal
Rate of progression from use to addiction is dependent on what?
Genetics, childhood abuse, specific drug
All drugs a/w a vicious cycle of addition work through what pathway?
Dopamine system = euphoria
Continued use of opioids after addiction can lead to what negative consequences?
Loss of behavioral control
Little regard for consequences of action
Brain is working on drive systems- stimulus driven (no off switch)
What is prescribed for mild pain according to the WHO pain ladder?
Non-opioid +/- adjuvant
(acetaminophen, aspirin, NSAID)
What is prescribed for mild-mod pain according to the WHO pain ladder?
Opioid +/- non-opioid +/- adjuvant
(codeine, tramadol)
What is prescribed for mod-severe pain according to the WHO pain ladder?
Opioid +/- non-opioid +/- adjuvant
(morphine, fentanyl)
When should CII opioids be used? (time frame)
Short-term
When does risk of continued opioid use increase?
4-5 days
How is drug-seeking behavior defined?
Over-reporting/ fabrication of sxs to obtain prescriptions for controlled substances
What pharmacologic properties are a/w drug seeking behavior?
Euphorigenic
Rapid onset/ high potency/ short duration
High purity/ water soluble
Brand name drugs
What pain meds are often sought after w/ drug seeking behavior?
Opiates- percocet, vicodin, morphine
What sleep aids are often sought after w/ drug seeking behavior?
Benzos- xanax, valium, ambien
What muscle relaxants are often sought after w/ drug seeking behavior?
Barbiturates- soma
Opioid use disorder is defined as a problematic pattern of use leading to impairment with 2 of what criteria? (11) :/ sorry
- Craving
- Tolerance
- Withdrawal
- Continued use despite social problems
- Continued use despite knowledge of problem
- Activities given up to use
- Failure to fulfill obligations
- Larger amounts for longer time
- Unsuccessful at controlling use
- Time to acquire, use, recover
- Use in physically hazardous situations
What are the specifiers for OUD? (3)
Early (> 3 mos) or late remission (> 12 mos)
On maintenance therapy (MAT)
Severity
How do you differentiate between mild, mod and severe OUD?
Mild- 2-3 sxs
Mod- 4-5 sxs
Severe- 6+ sxs
What is the protocol for detox if mod to severe independence?
In-patient
What drugs are used for overdose and SNS overstimulation respectively?
Overdose- naloxone (Narcan)
SNS overstimulation- Clonidine
What can be used for detox as a substitution of longer acting opioid?
Methadone
(also taper)
What drugs are used for extended tx for OUD?
Methadone or Buprenorphine
(taper)
What non-pharm tx is included in the extended tx for OUD?
Individual and group counseling
(narcotics anonymous)
What was the 1st med developed to tx opiate addiction in physicians office?
Buprenorphine (suboxone)
Although buprenorphine binds to the same my receptors, why is used for tx of OUD? (3)
Weak agonist- reduces cravings
Partial antagonist- prevents euphoria
Long acting/ decreased respiratory depression
What med requires DEA ‘X’ license/ MAT training and has best success with careful monitoring?
Buprenorphine
What Acts have contributed to medication assisted tx of OUD?
Drug abuse tx act (clinicians to prescribe narcotics to tx OUD out-pt)
Comprehensive addiction and recovery act (NPs and PAs becoem DATA waive eligible)
