'antineuritical' originates from the combining form 'anti-' (from Greek 'anti-' meaning 'against') + 'neur-' (from Greek 'neûr-' meaning 'nerve') + the adjectival suffix '-ical' (from Latin/Greek formation).

'antineuritical' was formed from the adjective/noun 'antineuritic' (used in medical English) by the addition of the suffix '-ical', following 19th-century medical usage to create adjectives meaning 'acting against neuritis'.

Initially it was used in medical contexts to mean 'opposed to or preventing neuritis'; over time the term has remained narrowly medical and is now rare, largely replaced by 'antineuritic' or more specific pharmacological terms.
