Acetylcholinesterase degrades acetylcholine, so acetylcholinesterase inhibitors stop acetylcholinesterase from breaking down acetylcholine, which ends up increasing the concentration of acetylcholine around muscle cells and helps counteract the effects of acetylcholine receptor antibodies.

AChE水解乙酰胆碱，所以AChE抑制剂可以阻止AChE分解乙酰胆碱，从而增加肌肉细胞附近的ACh浓度，减少ACh受体抗体的影响。
