Immediate-release refers to a type of medication formulation designed to dissolve quickly after ingestion, allowing the active ingredients to be released into the bloodstream without delay. This means that patients can experience the effects of the medication shortly after taking it, which is particularly beneficial for conditions requiring rapid relief. These formulations are commonly used in various medications, including pain relievers, antidepressants, and antibiotics. Immediate-release medications are typically taken multiple times a day to maintain their effectiveness, as their effects may wear off relatively quickly compared to extended-release or controlled-release formulations.
