摘要: Nanolipidic Particles (NLPs) having average mean diameters of 1 nm to 20 nm are made from a precursor solution. NLPs can be loaded with a desired passenger molecule. Assemblies of these particles, called NLP assemblies, result in a vehicle population of a desired size. Single application or multifunction NLP assemblies are made from the loaded NLPs and range in size from about 30 to about 200 nm. A method of using preloaded NLPs to make larger carrier vehicles or a mixed population provides increased encapsulation efficiency. NLPs have application in the cosmetics, pharmaceutical, and food and beverage industries.

摘要: A new and substantially improved type of lipid vesicle, called stable plurilamellar vesicles (SPLVs), are described, as well as the process for making the same and X-ray diffraction methods for identifying the same. SPLVs are characterized by lipid bilayers enclosing aqueous compartments containing one or more entrapped solutes, the concentration of such solutes in each aqueous compartment being substantially equal to the concentration of solutes used to prepare the SPLVs. The bilayers of SPLVs are substantially non-compressed. SPLVs are stable during storage and can be used in vivo for the sustained release of compounds and in the treatment of disease.

摘要: The invention encompasses mixtures of antimicrobial agents coencapsulated in liposomes which when administered in vivo exert an enhanced therapeutic effect. The therapeutic effectiveness of the coencapsulated antimocrobial agents is greater than that of the same combination administered either in solution or as a mixture of liposome populations each containing one of the antimicrobial agents.

摘要: Dehydrated liposomes are prepared by drying liposome preparations under reduced pressure in the presence of one or more protective sugars, e.g., the disaccharides trehalose and sucrose. Preferably, the protective sugars are present at both the inside and outside surfaces of the liposome membranes. Freezing of the liposome preparation prior to dehydration is optional. Alternatively, the protective sugar can be omitted if: (1) the liposomes are of the type which have multiple lipid layers; (2) the dehydration is done without prior freezing; and (3) the dehydration is performed to an end point which results in sufficient water being left in the preparation (e.g., at least 12 moles water/mole lipid) so that the integrity of a substantial portion of the multiple lipid layers is retained upon rehydration. Concentration gradients capable of generating transmembrane potentials can be created across the liposome membranes either before or after dehydration, and the transmembrane potentials resulting from these gradients can be used to load charged materials, e.g., drugs, into the liposomes.
