What are the opioid agonists-antagonists
butorphanol
pentazocine
buprenorphine
butorphanol
opioid agonist antagonist
pentazocine
opioid agonist antagonist
buprenorphine
opioid agonist antagonist
Binds to a pain receptor but causes a weaker pain response than a full ____
Mu, Kappa, delta receptors must be receptive to drugs; mu is most important (morphine)
not used as a first line analgesic
can cause respiratory depression but not usually as bad
Headaches, nausea
increased cardiac workload
agonist
agonist antagonist pharmacologic action
Respiratory depression (limited)
Sedation, dizziness, lightheadedness, drowsiness
Headache
Nausea
Increased cardiac workload with butorphanol and pentazocine
Abstinence syndrome – have withdrawal (less severe than opioid dependent)
agonists antagonists adverse effects
Measure baseline vital signs
Ask about opioid usage
Monitor respirations, if < 12 withhold medication and stimulate breathing
Fall precautions
Consider recommending an alternative if N/V doesn’t resolve
Do not administer to patients with myocardial infarction or cardiac insufficiency
agonists-antagonists interventions
IM, IV or intranasally
Pentazocine (Talwin) is only given orally
Measure baseline vital signs before administration and monitor throughout therapy, hold if resp rate < 12
Have naloxone (Narcan) and resuscitation equipment available (hard to reverse respiratory depression)
For intranasal administration, give one spray and repeat every 60-90 minutes as needed
For preop IM administration, give 60-90 minutes before surgery
Monitor therapeutic effects
Do not discontinue abruptly
agonist antagonists administration
only use wen needed and for short a term as possible
don’t want them operating heavy machinery or tasks that require alterneess until we know how the drug works with them
fall precautions
change possibitions gradually when standing us rising
report a worsening headache
tell then to lie down when feeling nauseated
should not use this drug for chest pain because of increased cardiac output that the drug will require
do not add opioids unless the doctor has approved it
agonists-antagonists patient instructions
Analgesic, Antiinflammatory and Antipyretic Activity
Also for headaches, myalgia, neuralgia, arthralgia, postoperative pain
Relief of pain with rheumatoid arthritis, juvenile arthritis, ankylosing spondylitis, osteoarthritis, gout, hyperuricemia
NSAIDS - Indications
What are the NSAIDS?
Aspirin
Ibuprofen
Naproxen
Indomethacin
Ketorolac
GI tract
Heartburn to GI Bleeding
Acute Renal Failure (especially if dehydrated)
Due to disruption of prostaglandin function
NSAIDS block protective effects of COX-1 on the kidneys
Reye’s Syndrome
Salicylism
