long-acting

Slow to fade

Long-acting describes medications or substances that remain effective in the body for an extended period, reducing how often doses are needed: long-acting insulin, long-acting birth control.

The term contrasts with short-acting or immediate-release formulations.

Outside medicine, long-acting can describe anything designed to work over a prolonged time: a long-acting fertilizer.
