Abstract
Polymerized liposomes, methods of preparing the polymerized liposomes and incorporating biologically active substances within the polymerized liposomes, and methods of administering polymerized liposomes containing a biologically active substance to be delivered to a patient are disclosed. The polymerized liposomes are prepared by polymerizing double bond-containing liposomes. The polymerization can be initiated with a source of radiation and/or a free radical initiator. Biologically active substances can be incorporated into both the hydrophilic and hydrophobic layers of the liposomes, either during or after polymerization. The polymerized liposomes can be administered orally to a patient in need of the biologically active substance to be delivered. Examples demonstrate enhanced stability.
