Question

Quizplus · Accepted Answer

Edrophonium is a cholinesterase inhibitor used in the diagnosis of myasthenia gravis. In a cholinergic crisis, caused by excessive medication, there is an overabundance of acetylcholine. Fasciculations (muscle twitching) are a sign of cholinergic crisis, not an improvement in myasthenic symptoms.
