Neostigmine is used to treat myasthenia gravis by improving muscle strength. It is a cholinesterase inhibitor, which is the opposite of the effects of other muscle relaxants, and it does not cross the blood-brain barrier.
By inhibiting acetylcholinesterase, Neostigmine in uae increases the availability of acetylcholine at the synapse, allowing more of it to bind to the fewer receptors present in myasthenia gravis and thus better stimulating muscle contraction.
