Sustained-release tablets are specially designed medications that release their active ingredients slowly over time. This allows for a more consistent level of the drug in the bloodstream, reducing the need for frequent dosing. They are often used for chronic conditions where maintaining stable drug levels is important. These tablets are engineered using various techniques, such as coating or embedding the drug in a matrix. This controlled release can improve patient compliance and minimize side effects. Common examples of medications that may come in sustained-release forms include pain relievers, antidepressants, and blood pressure medications.
