Mechanisms of action Flashcards
irreversibly (covalent), non-selectively inhibits COX, reducing PG and TXA2 synthesis
Aspirin (ASA)
inhibits COX and PG synthase
Acetaminophen
enhances 5-HT release (which attenuates pain mediator generation) and regulates body temperature by acting centrally
Acetaminophen
A_____ acts centrally whereas A______ acts peripherally in pain relief
Acetaminophen, Aspirin
Selectively, reversibly (non-covalent) inhibits COX-2 and reduces PG synthesis
Celecoxib
which two opium alkaloids are synthetic?
Hydrocodone and Heroin
which two opium alkaloids are naturally occurring?
Morphine and Codeine
Act through G-protein coupled Mu, Delta, Kappa opioid receptors, stimulate prolactin and growth hormone release
Hydrocodone/Acetaminophen
Hyperpolarization with Hydrocodone/Acetaminphen is caused by outflow/decrease in _____ and increase/influx of _____
Potassium (K+); Chloride (Cl-)
central acting synthetic opioid
Tramadol
agonist selective for mu receptors and weak inhibitor of NE/5-HT reuptake
Tramadol
unilateral, pulsating, lasting 2-72 hours
Migraine
behind or around one eye, excruciating, sharp pain, lasting 15-90 minutes
Cluster headaches
bilateral around head, dull/persistent, driven by stress, up to 7 days per episode
Tension headaches
prophylactic migraine therapy
Topiramate
