Module 5: Unit D Opioids Flashcards
What are the effects of opioid use in the preconceptual period?
Opioid use in the periconceptional period appears to be associated with a 2.2-fold increased risk of neural tube defects
Opioids-Strong agonist example
Morphine
Hydromorphone
Demerol
Fentanyl
Indication strong-agonist (morphine, etc.)
Moderate to severe pain (post-op pain, labor and delivery pain, chronic cancer pain).
MOA Morphine, etc.
Activate Mu and Kappa receptors. Produce analgesia, resp depression, and euphoria.
Safety in morphine (strong agonist)
Respiratory depression death from overdose. Avoid in the young and old, avoid with resp disease (asthma COPD).
Causes orthostatic hypotension, urinary retention, emesis, sedation, neurotoxicity, and tolerance and dependence.
Many see textbook charts but especially CNS depressants, Benzos, and alcohol.
BBW morphine, hydromorphone, etc.
Resp depression in both opioid naïve and opioid-tolerant patients. Monitor for resp depression, especially after new-onset therapy or escalation in does.
Indication Methadone
Medicated assisted treatment
MOA methadone
Activate Mu and Kappa receptors. Produce analgesia, resp depression, and euphoria.
Safety methadone:
Respiratory depression death from overdose. Avoid in the young and old, avoid with resp disease (asthma COPD).
Causes orthostatic hypotension, urinary retention, emesis, sedation, neurotoxicity, and tolerance and dependence.
Many see text charts but esp CNS depressants, Benzos, and alcohol.
Methadone prolongs Qt interval (ECG) before starting.
Opioids-Moderate agonist example
Codeine
Hydrocodone
oxycodone
indication opiod-moderate (codeine)
Mild to moderate pain
Effective cough suppressant
MOA Codeine
bind to mu-opioid receptors in the brain. This produces endorphins and gives pain relief.
Safety codeine
Not be used to treat pain or cough, and tramadol should not be used to treat pain in children younger than 12 years.
Recommend against their use in adolescents between 12 and 18 years who are obese or have conditions such as obstructive sleep apnea or severe lung disease, which may increase the risk of serious breathing problems.
Not recommended when taking codeine or tramadol medicines due to the risk of serious adverse reactions in breastfed infants. These can include excess sleepiness, difficulty breastfeeding, or serious breathing problems that could result in death.
BBW codeine
CYP2D6 ultrarapid metabolizers have led to death in children and breastfeeding infants
Opioids Partial agonist example
Buprenorphine (Subutex)
