Q

hyoscine = scopolamine

A

muscarine antagonist:
doornappel
onderdrukken muscarine receptoren in evenwichtsorgaan => goed bij reisziekte

Q
  1. neuromuscular blocking agents: NON-DEPOLARIZING
A

Competitive antagonism of the nicotinic receptor at the neuromuscular junction.
-> tubocurarine, atracurium, cisatracurium

paralysis, not preceded by contractions
can be counteracted by cholinesterase inhibitors
in combination with atropine

Q

neuromuscular blocking agents - DEPOLARIZING

A

Agonism of the nicotinic receptor at the
neuromuscular junction with increased activation
-> suxamethonium

paralysis, preceded by contractions
cannot be counteracted (echter kortdurig)

Q
  1. cholinesterase inhibitoren - DO NOT PASS BBB
A

neostigmine
pyridostigmine

cf muscarine agonisten (glaucoma, bladder atony)
myasthenia gravis
veel gebruikt bij anesthesie voor counteracting

11
Q

Myasthenia gravis

A

antilichamen tegen nicotine receptoren op de musculaire eindplaat => verminderde contractiekracht

Behandeling:
cholinesterase inhibitoren => meer Ach
=> grotere kans dat de nog overgebleven nicotine receptoren bezet zullen zijn
