Neostigmine bromide Chemical Properties,Usage,Production
Chemical Properties
Crystalline Solid
Uses
antiscorbutic, antiviral
Uses
Cholinergic; miotic; antidote (curare)
Uses
A reversible acetylcholinesterase inhibitor
Uses
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.
Definition
ChEBI: Neostigmine bromide is the bromide salt of neostigmine. It contains a neostigmine.
General Description
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.
Biological Activity
neostigmine bromide is a reversible inhibitor of acetylcholinesterase.[1]ache (acetylcholinesterase) is a hydrolase that hydrolyzes the neurotransmitter acetylcholine at the neuromuscular junction and cholinergic synaspe. it terminates the signal transductions and plays a role in neuronal apoptosis.neostigmine bromide is a quaternary amine that blocked cholinesterase activity to extend and enhance the muscarinic and nicotinic effects of acetylcholine. it is implicated for the treatment of primary open-angle glaucoma, postoperative urinary retention, paralytic ileus, myasthenia gravis etc. it is also reported to be an adjuvant to local anaesthetics and opioids for post-surgical pain after gynaecological or abdominal surgery. [1]
Biochem/physiol Actions
Neostigmine bromide is a quaternary amine. It is involved in elongating and boosting the muscarinic and nicotinic effects of acetylcholine by inhibiting cholinesterase activity. It is used in anesthesia to reverse the neuromuscular blockade produced by competitive neuromuscular blockers.
Clinical Use
Use of physostigmine, as a prototype of an indirect-actingparasympathomimetic drug, facilitated the development ofstigmine, in which a trimethylamine group was placed para toa dimethylcarbamate group in benzene. Better inhibition ofcholinesterase was observed when these groups were placedmeta to each other as in neostigmine, a more active and usefulagent. Although physostigmine contains a methylcarbamatefunctional group, greater chemical stability towardhydrolysis was obtained with the dimethylcarbamyl group inneostigmine.
Safety Profile
Poison by ingestion, subcutaneous, intravenous, and intraperitoneal routes. When heated to decomposition it emits very toxic fumes of Br-, NH3, and NOx. See also CARBAMATES and BROMIDES.
Purification Methods
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).
