Abstract
Drug-loaded microbead compositions include microbeads of a biodegradable material and vesicular agents located within or associated with the biodegradable material of the microbeads. The vesicular agents include a lipid bilayer and comprise liposomes or ethosomes. The drug-loaded microbeads include 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.
