Postsynaptic Flashcards
how is Each related to Ena and Ek?
it is in between.
what is the fastest type of signal transduction motif
ligand-gated channels
which type of block uses competitive inhibition?
non-depolarizing
Depolarizing Block: what chemicals, phases
nicotinic receptor agonists in high [ ]. Depolarize then block transmission. Phase 1-block by depolarization. Phase 2-block by desensitization
Tubocurarine
non-depolarizing blocker, prototype
what muscles must be relaxed to intubate
masseter, laryngeal
what does -curonium mean? -curium?
steroid, benzylisoquinolinium
pancuronium: duration, side effects, excretion
long duration. blocks vagal tone (tachycardia). renal excretion
vecuronium: duration, side effects, excretion
intermediate, no CV effects, biliary excretion
atracurium and cisatracurium: duration, excretion, best uses
intermediate, hoffman elimination, RENAL FAILURE pts. Cis has no histamine and no seizures
rocuronium: popular for? elimination?
intubation. biliary
succinylcholine: uses, structure, side effects, contraindication, metabolism
intubation, 2 ach end to end, malignant hyperthermia, burn victims (elevated serum K leads to CV collapse), plasma cholinesterases
malignant hyperthermia: problem, treatment
ryantodine receptor hypersensitivity so it remains open and muscle contracts. Give Dantrolene
dantrolene
given for malignant hyperthermia
excretion for most of these drugs and exceptions.
Kidney. vecuronium and rocuronium are BILIARY
