PharmExam4- composition/MOA Flashcards
(45 cards)
active metabolite Nortriptiline
amtriptiline
most potent, selective inhibitor of NE reuptake
imipramine
most selective for inhibition of serotonin reuptake
clomipramine
unique: NO action on transporters; EXTREMELY strong affinity for histamine
trimipramine
D2 receptor antagonist; mixed antidepressant and neuroleptic
amoxapine
unique- binds NE but HIGHER affinity for dopa
buproprion
antagonist at 5HT2/3 and H1
mirtazepine
block sero and NE?
SNRIs
block 5HT2a and 5HT1a at high doses
trazadone
blocks 5HT2
nefazodone
serotonin reuptake blockade, potent inhibitor of P450
SSRIs
substitute for sodium
lithium
blocks turnover and release of dopa and NE but INCREASED SEROTONIN
lithium
depletes phosphatidylinositol-4,5 biphosphate (PIP2)
lithium
reversibly inhibits nerve conduction .. binds and inhibits opening of sodium channels on INTRACELLULAR side
local anesth.
prototype, competitive antagonist at nicotinic receptor
curarine
prevents depolarization by Ach (hypotension from histamine release)
d-Tubocurarine
laudanosine metabolite, histamine release
atracurium
NO laudanosine, no histamine release, more potent
CISatracurium
non depolarizing steroid that blocks muscarinic receptors (part of triple cocktail lethal injxn)
pancuronium
non depolarizing steroid that has slight antimusc effects, for ppl w/ CV probs
rocuronium
nicotinic agonist- fasiculations followed by desensitized
succinylcholine
alpha 2 agonist, spasmolytic
tizanidine
blocks ryanodine receptor in Ca release channels
dantrolene
