Polymeric Coatings for Drug Delivery Industry Research Report 2026

Definition

Polymeric coatings for drug delivery are drug-containing polymer layers engineered on a product surface to store an active pharmaceutical ingredient and govern its release to the surrounding tissue or fluid environment over a defined time window. The polymer functions as the structural matrix that immobilizes the drug and controls transport through mechanisms such as diffusion, polymer swelling, and, when bioresorbable chemistries are used, hydrolytic degradation, enabling release profiles that range from rapid transfer to sustained elution. In medical devices, these coatings are implemented as single-layer or multi-layer architectures, including matrix-dispersed and reservoir designs, and are built from durable polymers or bioresorbable polyesters.
