    摘要: The present invention provides lipid-based systemic delivery vehicles and method for selectively targeting an active agent to a specific tissue site. The methods include designing a lipid-based systemic delivery vehicle having a plurality of constitutent parts, and thereafter varying the amounts of each of the plurality of constituent parts to impart tissue selectivity. After tissue selectivity is imparted it is possible to selectively target an active agent to a specific tissue site.

    摘要: Fully lipid-encapsulated therapeutic agent particles of a charged therapeutic agent are prepared by combining a lipid composition containing preformed lipid vesicles, a charged therapeutic agent, and a destabilizing agent to form a mixture of preformed vesicles and therapeutic agent in a destabilizing solvent. The destabilizing solvent is effective to destabilize the membrane of the preformed lipid vesicles without disrupting the vesicles. The resulting mixture is incubated for a period of time sufficient to allow the encapsulation of the therapeutic agent within the preformed lipid vesicles. The destabilizing agent is then removed to yield fully lipid-encapsulated therapeutic agent particles. The preformed lipid vesicles comprise a charged lipid which has a charge which is opposite to the charge of the charged therapeutic agent and a modified lipid having a steric barrier moiety for control of aggregation.
