Immediate release refers to a method of delivering medication where the active ingredients are released into the bloodstream quickly after ingestion. This allows for rapid onset of action, making it suitable for conditions that require prompt relief, such as pain or anxiety. In contrast to extended-release formulations, which release the drug slowly over time, immediate release medications are designed to provide a quick therapeutic effect. Common examples include over-the-counter pain relievers like ibuprofen and acetaminophen, which are often used for fast relief of symptoms.
