A cholinesterase inhibitor that is given in the form of a bromide salt, C12H19BrN2O2, or a methyl sulfate, C13H22N2O6S, used to treat myasthenia gravis and muscle atony and to reverse the effects of muscle relaxants after surgery.

neostigmineAn ANTICHOLINESTERASE drug used in the treatment of MYASTHENIA GRAVIS. Neostigmine interferes with the enzyme that breaks down the neurotransmitter ACETYLCHOLINE and so prolongs its action. The drug is on the WHO official list. A brand name is Robinul neostigmine.
A reversible anticholinesterase drug, which neutralizes the effect of acetylcholinesterase and thereby allows the prolonged action of acetylcholine on the iris and ciliary muscle. Its action is similar to physostigmine but it is not so irritating a miotic. Both are occasionally used in the treatment of glaucoma. See acetylcholine; parasympathomimetic; physostigmine; miosis; miotics.
