immediate release
Available right now
Immediate release describes medication formulated to deliver its full dose quickly after ingestion, without any mechanism to delay or extend absorption.
This contrasts with extended-release or sustained-release formulations designed to work gradually: The doctor switched her from immediate release to extended release for better overnight coverage.
Often abbreviated IR in pharmaceutical contexts.
