Macromolecule or polymer used to transport a pharmacologically active compound to be released later on due to an abiotic or biotic process.
Note: A complementary property of a polymeric drug carrier is targeting, which can be obtained by specific interactions with a receptor if bearing a specific ligand or by selection depending on other factors such as permeation through membranes or capillaries.
