Controlled-release medications are specially designed to release their active ingredients slowly over time. This allows for a more consistent level of the medication in the bloodstream, which can improve effectiveness and reduce side effects. These medications are often used for chronic conditions, where maintaining stable drug levels is important for treatment. These formulations can come in various forms, such as tablets or capsules, and are often labeled as extended-release or sustained-release. By controlling the release rate, patients may need to take the medication less frequently, enhancing convenience and adherence to their treatment plans.
