Abstract
Drug-loaded microbead compositions include microbeads of a water-swellable polymer material and a complex of a carrier and a therapeutic agent chemically bonded to the carrier. The complex is embedded in the polymer material. Methods for preparing the drug-loaded microbead compositions and embolization compositions include loading a therapeutic agent into a water-swellable polymer material to form microbeads, then removing water from the microbeads. Additional drug-loaded microbead compositions include microbeads of a biodegradable material, vesicular agents, a first therapeutic agent associated with the vesicular agents, and a second therapeutic agent different from the first therapeutic agent. The vesicular agents include a lipid bilayer surrounding a vesicular core. The second therapeutic agent is contained within the microbeads or associated with the microbeads through ionic or non-covalent interaction and may or may not be associated with the vesicular agents. Drug-loaded biodegradable microbead compositions include microbeads of biodegradable material and a therapeutic agent.
