Etymology: Neostigmine is a chemical coinage, named by building on an older drug name. Its model was physostigmine, the alkaloid first isolated from Calabar beans, whose name is built on the Greek "stigma" (a mark or spot), a reference to the bean's distinctive marking, with the chemical suffix "-stigmine" added to it. Chemists then took the "-stigmine" ending as a family marker for compounds of this type. The prefix "neo-" comes from Ancient Greek "néos", meaning "new". Put together, the name says "a new drug in the physostigmine family," signalling that it was a modified relative of that earlier compound rather than an entirely unrelated substance.

Synonyms: stigmin
