"Sustained release" refers to a method of drug delivery that allows medication to be released over an extended period rather than all at once. This technology is designed to maintain therapeutic drug levels in the bloodstream for a longer duration, ultimately improving the efficacy and consistency of treatment. By releasing the active ingredient gradually, sustained-release formulations can enhance patient compliance, as they may require fewer doses throughout the day compared to immediate-release forms.

This approach minimizes peaks and troughs in drug concentration, which can lead to better control of symptoms and side effects. It is particularly beneficial for medications that need to maintain stable levels in the body for effective management of various conditions.

In contrast, other options such as rapid release would not provide the long-lasting effects associated with sustained release, and processes that diminish a drug's effectiveness or strategies solely to reduce costs do not relate to the concept of sustained release in pharmacology.
