What is "distigmine"

n. A parasympathomimetic drug, used in the bromide form, similar to pyridostigmine and neostigmine but with a longer duration of action.

Distigmine (as distigmine bromide) is a parasympathomimetic. Distigmine is similar to pyridostigmine and neostigmine but has a longer duration of action. It is available as tablets on prescription only. Distigmine has a greater risk of causing cholinergic crisis because of accumulation of the drug being more likely than with neostigmine or pyridostigmine and so distigmine is rarely used as a treatment for myasthenia gravis, unlike pyridostigmine and neostigmine.
