Sustained-release medications are designed to release their active ingredients slowly over time. This allows for a more consistent level of the medication in the bloodstream, reducing the need for frequent dosing. These formulations can improve patient compliance and minimize side effects by avoiding peaks and troughs in drug levels. These medications are often used for chronic conditions, such as hypertension or diabetes, where maintaining stable drug levels is crucial. Common forms include extended-release tablets and capsules, which are engineered to dissolve gradually. This approach helps ensure that patients receive the therapeutic effects of the medication throughout the day.
