antiscorbutic, antiviral


Cholinergic; miotic; antidote (curare)

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.

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).
