'pro-medication' is a modern English compound formed from the prefix 'pro-' and the noun 'medication'. 'pro-' ultimately comes from Latin 'pro', where 'pro' meant 'for', and 'medication' comes from Latin 'medicatio' (from 'medicus'/'medic-'), where 'medic-' related to healing or medical treatment.

'pro-medication' was created in contemporary English by combining the prefix 'pro-' with the existing word 'medication'. The element 'medication' entered English via Middle French 'medication' from Latin 'medicatio', and 'pro-' is a long-established Latin-derived prefix used in English to mean 'in favor of' or 'for'.

The components originally meant 'for' (pro-) and 'treatment by medicine' (medication); the combined form has been used in recent English to denote a viewpoint or stance 'in favor of using medications' rather than to name a specific medical product.
