Dementia & Pain Flashcards
What is Naproxen?
reversible non selective NSAID w/ longer 1/2 time that permits 1x/day dosing
for pts w/ CV issues
What are paresthesias?
abnormal sensation (numbness, pins & needles)
What do IV opioids, alpha2 agonists and general anesthetics module?
perception of pain
What is ziconotide?
last resort drug that blocks N-type voltage-sensitive Ca2+ channels on afferent nerves in dorsal horn
MOA of ketamine
noncompetitive NMDA receptor antagonist
IV anesthesia, lower doses for chronic pain
MOA of lasmiditan
5HT1F agonist to tx migraines & decrease trigeminal stimulation (w/o vasoconstriction)
What lethal effect caused by acetaminophen OD?
hepatotoxicity
MOA of aspirin
NSAID that irreversibly inhibits COX1, COX2, for lifetime in platelets
What is dysesthesia?
unpleasant abnormal sensation
MOA of ibuprofen
reversible NSAID
increase risk of MI, stroke
What risk increased w/ aspirin & warfarin use?
risk of BLEEDING
MOA of pregabalin
inhibits NT release @ nerve terminals
neuropathic pain (DM neuropathy, SC injury, postherpetic neuralgia)
MOA of donepezil
reversible noncompetitive inhibitor of AChE
prolongs signaling of ACh in synaptic cleft
What is hypoalgesia?
diminished response to normally painful stimulus
MOA of acetaminophen
NO tx of inflammation
monotherapy for fever reduction
temporary relief of mild to moderate pain
What is potentially lethal consequence of aspirin toxicity?
metabolic acidosis
MOA of dexmedetomidine
selective A2 receptor agonist
IV for sedation, analgesia
MOA of capsaicin
stimulates TRPV1 receptors
depletes substance P from neurons tx nociceptive & neuropathic pain
What is added to acetaminophen to extend its utility in management of moderate to severe pain?
opioids (stimulate mu receptors)
