Quizplus · Accepted Answer

Myasthenia gravis is caused by a reduction in acetylcholine at the neuromuscular junctions. Therefore, the drug used to treat it needs to increase acetylcholine levels. Cholinergic drugs stimulate the release or mimic the action of acetylcholine, making them the likely choice for treatment. Cholinergic blockers (A) and adrenergic drugs (B and D) would be counterproductive in this case.
