Prolonged Action

Definition of Prolonged Action from the PharmacyDictionary.in

Prolonged Action

A dosage form that delivers an initial dose for a quick therapeutic response, followed by a sufficient dose (or a series of doses) to maintain an effective drug concentration for an extended period of time (usually 8 to 12 hours for orally administered medication). This contrasts with a single-dose entity that is effective for a shorter time.
