Extended-release refers to a formulation of medication designed to release its active ingredients slowly over time. This allows for a more consistent level of the drug in the bloodstream, reducing the need for frequent dosing. Extended-release medications are often used for chronic conditions, where maintaining stable drug levels is important for effectiveness. These formulations can improve patient compliance, as individuals may prefer taking a medication once or twice a day instead of multiple times. Common examples of extended-release medications include certain types of pain relievers, antidepressants, and blood pressure medications.
