  • Triggered release of liposomal drugs following mixing of cationic and anionic liposomes
    Patent number: 7273620
    Abstract: Methods and compositions for triggering the delivery of an encapsulated therapeutic agent from a liposome are provided. Liposomes of opposite charge and incorporating lipids which favor non-lamellar structures are contacted in vivo. At least one of the liposome encapsulates at least one therapeutic drug or agent.
