Opioids (Exam 2) Flashcards
Opioids for Pain Releif
-Morphine
-Hydromorphone
-Fentanyl
-Meperidine
-Codeine
-Oxycodone
-Hydrocodone
-Narcan/nalaxone (antidote)
General considerations for all Opioids
-All of them are HIGH ALERT DRIGS
-Assess LOC, BP, Pulse, and Respirations before and periodically during administration
-If RR is <10 min assess level of sedation (Respiratory depression is our BIGGEST CONCERN)
-Physical stimulation may be sufficient to prevent significant hypoventilation
-Subsequent does may need to be decrease by 25-50%
3 chemical classes of opioids:
-Morephine-like
-Meperideine-like
-Methadone-like
morphine
-Drug prototype
-MOA: mu agonist —- mimics the action of ednogenous opioids at the mu receptors
(morphine bids to the mu receptors and creates a response)
-SCHEDULE 2
morphine: interactions
Alcohol and CNS depressents
Morphine: Indication
-Moderate to severe pain
Morphine: Adverse Reactons
SERIOUS:
-Respiratory Depression
-CNS depression
COMMON:
-Constipation
-Itching
-Dry mouth
-Do not give to patient who have not taken opioids medication before
morphine: nursing consideration
All opioids:
May impair the mental/physical abilities required for operating machinery or car
hydrmorphone
-Opioid similar to morphine
-synthetic formulation
-Schedule II
Hydromorphone: indication
-SEVERE PAIN
-7x more strong than morphine
hydromorphone: side effects
same as other opioids
Fentanyl: Indicaitons
Synthetic opioid for moderate-severe pain, surgical indication, and chronic pain
-PO (buccal) (IV) (IM) and Transdermal (chronic cancer)
Fentanyl potency
-EXTREMELY POTENT
-0.1 mg = 10 mg of morphine
DOSES IN MICROGRAMS
merpedridine
-Synthetic opioid and schedule 2
merperidine: indicaitons
-Moderate to severe pain
-Weaker than morphine and shorter duration
-Less respiratory depression
-PO is half as effective as IV
-LOTS OF DRUG/DRUG interactions
