releases immediately

Etymology
Etymology Information

'immediate-release' originates from modern English, formed by combining the adjective 'immediate' and the noun/verb 'release' to denote a formulation that releases immediately.

Historical Evolution

'immediate' comes from Latin 'immediatus' (in- 'not' + medius 'middle') via Old French and Middle English; 'release' comes from Old French forms (e.g. 'releser'/'relaisser') ultimately from Latin roots such as 'relaxare' meaning 'to loosen'. The compound usage 'immediate-release' developed in 20th-century pharmaceutical English to contrast with terms like 'extended-release'.

Meaning Changes

Individually, 'immediate' originally meant 'not separated by anything' and 'release' meant 'to loosen or set free'; combined in modern pharmaceutical usage the term specifically means 'to let the active ingredient become available right away', a specialized shift from the general senses.
