Functional Coatings for Controlled Drug Release Controlled-release medications rely heavily on specialized coatings that regulate the timing of drug release. These coatings can delay release, extend release over several hours, or target specific regions within the digestive tract. The science behind such coatings involves understanding polymer behavior, fluid dynamics, and gastrointestinal conditions. As chronic diseases become more common, demand for long-acting medications increases, creating opportunities for functional coating technologies to play an even larger role in therapeutic design.
