neostigmine

neostigmine test

muscle weakness caused by myastenia gravis is temporarily reversed following the administration of neostigmine; used as a diagnostic test.

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.
