Quizplus · Accepted Answer

Edrophonium (Tensilon) is a short-acting acetylcholinesterase inhibitor that can be used for diagnostic purposes in myasthenia gravis. In patients with myasthenia gravis, there will be an improvement in muscle strength after administration of edrophonium. This diagnostic test is also known as the Tensilon test. Pyridostigmine (Mestinon), Neostigmine (Prostigmin), and Ambenonium (Mytelase) are also acetylcholinesterase inhibitors but are not typically used for diagnostic purposes in myasthenia gravis.
