A) Galantamine
B) Pyridostigmine
C) Donepezil
D) Bethanechol
B
Feedback:
Pyridostigmine is preferred in some cases for the management of myasthenia gravis because it does not need to be taken as frequently and can be given parenterally for patients who are having difficulty swallowing. Galantamine and bethanechol cannot be given parenterally to the patient having difficulty swallowing. Donepezil is not indicated for the treatment of myasthenia gravis but is used to manage Alzheimer dementia, including severe dementia.
