Feedback:
Edrophonium is the drug of choice for diagnosing myasthenia gravis. Bethanechol is used to treat neurogenic bladder. Neostigmine is used for treatment of myasthenia gravis and could be used for diagnosis if edrophonium could not be used. Atropine is an anticholinergic drug and would not be used to test for myasthenia gravis.
