'pyramidon' originates from German, specifically the word 'Pyramidon', which was derived from the chemical structure resembling a pyramid and the suffix '-on' used in chemical nomenclature.

'Pyramidon' was coined in the late 19th century in German scientific literature and was adopted into English as the name for the compound aminopyrine.

Initially, it referred specifically to the chemical compound aminopyrine, and this meaning has remained unchanged.
