'antiapoplectic' originates from Modern English, formed by the prefix 'anti-' (from Greek 'anti', meaning 'against') combined with 'apoplectic' (from Greek 'apoplektikos').

'apoplectic' comes from Greek 'apoplektikos' (from 'apoplexia' meaning 'a striking down'), passed into Latin as 'apoplexia' and Middle English as 'apoplexie'/'apoplectik', and later combined with the productive English prefix 'anti-' to form 'antiapoplectic'.

Initially related to being 'struck down' (physically overwhelmed by a sudden seizure/strike), over time 'apoplectic' broadened to include extreme fury; 'antiapoplectic' thus evolved to mean either 'preventing stroke' or, figuratively, 'preventing extreme rage'.
