Drugs that inhibit cholinesterases. The neurotransmitter ACETYLCHOLINE is rapidly hydrolyzed, and thereby inactivated, by cholinesterases. When cholinesterases are inhibited, the action of endogenously released acetylcholine at cholinergic synapses is potentiated. Cholinesterase inhibitors are widely used clinically for their potentiation of cholinergic inputs to the gastrointestinal tract and urinary bladder, the eye, and skeletal muscles; they are also used for their effects on the heart and the central nervous system.
Drugs that mimic the effects of parasympathetic nervous system activity. Included here are drugs that directly stimulate muscarinic receptors and drugs that potentiate cholinergic activity, usually by slowing the breakdown of acetylcholine (CHOLINESTERASE INHIBITORS). Drugs that stimulate both sympathetic and parasympathetic postganglionic neurons (GANGLIONIC STIMULANTS) are not included here.

用途コリンエステラーゼ阻害剤。
使用Neostigmine bromide has been used as an acetyl cholinesterase (AChE) inhibitor: to control reaction specificity of acetylcholinesterase in coronal organ of Botryllus schlosseri.to study its effects on abnormal contraction of pyloric circular smooth muscle strips (PCSMS).to study its effects on depolarization of bag cell neurons.
一般的な説明Neostigmine bromide, (m-hydroxyphenyl)trimethylammonium bromide dimethylcarbamateor the dimethylcarbamic ester of 3-hydroxyphenyltrimethylammoniumbromide (Prostigmin bromide), is usedas an antidote to nondepolarizing neuromuscular blockingdrugs and in the treatment of myasthenia gravis. It occurs asa bitter, odorless, white, crystalline powder. It is soluble inwater and alcohol. The crystals are much less hygroscopicthan those of neostigmine methylsulfate and thus may beused in tablets. Solutions are stable and may be sterilized byboiling. Aqueous solutions are neutral to litmus.

純化方法Crystallise neostigmine bromide from EtOH/diethyl ether. Its solubility in H2O is ~50%. [Beilstein 13 III 939.] (It is cholinergic and highly TOXIC.) The starting material 3-dimethylcarbamoyl-N,N-dimethylaniline [59-99-4] has b 195o/20mm [Beilstein 13 III 936], and its picrate has m 138o (from EtOH).
