'antidysuric' originates from New Latin/modern medical formation, specifically the elements 'anti-' (from Greek 'anti') and 'dysuria' (from Greek 'dys-' + 'ouron'), where 'anti-' meant 'against', 'dys-' meant 'bad' or 'difficult', and 'ouron' meant 'urine'.

'antidysuric' changed from New Latin formation 'antidysuricus' (a coinage combining 'anti-' and 'dysuria') and was adopted into modern medical English as 'antidysuric'.

Initially, it meant 'acting against dysuria', and over time this medical meaning has remained essentially the same as 'preventing or relieving painful/difficult urination'.
