Diagnose Myesthenia Gravis |
|
Neostigmine
|
Anticholinesterase
- Blocks Achase for house (kind of long acting) aka Carbamate |
|
Carbamate
|
Anticholinesterase

|
In a normal, resting person, what is the effect of a ___ blocker will be to decrease ___ effects
|
nicotinic, parasympathetic (since normal resting person experiences more parasympathetic stimulation)
|
|
atropine
|
Anti-muscarinic
|
|
