taper method
106
disulfiram (antabuse)

118
assessment tools for OUD
- clinical opioid withdrawal scale (COWS) - subjective opioid withdrawal scale (SOWS)
119
COWS
assess degree of withdrawal from opioids in order to determine readiness to be started on buprenorphine/naloxone
120
SOWS
self-administered tool used to determine degree of opioid withdrawal for potential inductions of suboxone outside of a medical setting (individuals home)
121
spectrum of treatments exist for OUD
- withdrawal management alone - opioid agonists (suboxone, methadone) - 24 hr slow-release oral morphine - inject hydromorphone - psychosocial treatment interventions - residential treatment - harm reduction
122
short-acting opioids withdrawal time
- 12 to 16 hr since last dose (heroin, morphine)
123
intermediate-acting opioids withdrawal time
- 17 to 24 hrs since last dose (slow-release oral morphine)
124
long-acting opioids withdrawal time
- 24 to 48 hrs or more since last dose (methadone)
125
clonidine for OUD
- decreases sympathetic outflow in response to narcotic withdrawal - tachycardia - hypertension - sweating - pilo-erection - doesn't decrease drug cravings - decreases physiological sx - taper - rebound syndrome - CAUSES HYPOTENSION
126
methadone indications
- metabolized by liver - once daily dose - half life is 25 hrs - single dose lasts for 24 hrs - blocks opioid receptors - decreases euphoria from opioid use - doesn't block effect or cravings from other drugs (coke)
127
whats the initial dose of methadone
30mg/day
128
methadone safety
- drug interactions, age, history of respiratory disease, other prescribed sedatives contribute to increased harm with methadone - tolerance is rapidly lost if doses are missed, or treatment is discontinued (3 days) - doses need to be adjusted or pt can suffer over sedation or respiratory depression
129
naltrexone (revia)
- reduces cravings - semi synthetic opioid antagonist - blocks opioid receptor sites - maintenance drug - opioid free 7-10 days before first dose - suicidial thoughts - caution with psych history - motivation important
130
buprenorphine
- partial agonist - long duration of action - indicated for opioid addiction - abuse potential - sedation - drowsiness - resp depression concern
131
buprenorphine/naloxone
- 4:1 ratio - SL route - naloxone component is induced only to prevent diversion & injection use
132
why is naloxone included in the tablet?
- only to prevent diversion and injection (has poor oral & SL bioavailability = not absorbed when tablet is taken as directed - if buprenorphine/naloxone is injected = naloxone component become active and results in rapid onset of withdrawal
133
facts about suboxone
- increased functional state - increased attendance at appointments - decrease drug use - increased work attendance - increase adherence to programs - decreased disease transmission - safer in OD - less euphoric, hypotension, resp depression, low sedation, decrease drug cravings
134
opioids and benzos both
decrease respiratory drive & should not be co-precribed
135
co-occurring substance use may include
various combos of legal, prescription, over the counter, and legal substances
136
co-occurring substance use is associated with
younger age, lower educational attainment, lower socioeconomic status, childhood abuse, and males

138
concurrent use of sedatives is associated with
increased risk of respiratory depression, overdose, and death
139
screening for co-occurring substance use disorders
- ASSIST (clinician-performed screening tool to identify high risk substance use in adult pts) - TAPS (tobacco, alcohol, prescription medication, and other substance use tool) - AUDIT-C1 (alcohol screener used to identify hazardous drinking or an active alcohol use disorder)
140
principles for treating co-occurring substance use disorders
- treatment concurrently - severity of each substance should guide treatment - should be triaged according to which carriers highest risk of mortality (prioritize OUD over weed disorder) - safety should be prioritized!!!!
141
examples of common presentations of co-occurring substances
- benzo & opioids - cocaine & alcohol - opioids & alcohol - tobacco & other substances
142
benzo use is associated with
higher risk of hep C, seroconversion, higher risk of HIV, increased risk of death
