  • Drug delivery systems
    Patent number: 5482719
    Abstract: A photoactivatable drug delivery system is provided, in which a drug is combined e.g. by covalent bonding, incorporation in a matrix or encapsulation, with a photosensitive macromolecule. In combination, the drug is inert. The macromolecule is large enough to prevent migration of the combination within the body, so that the combination can be implanted at a location of maximum effectiveness. The drug is released from the combination, in therapeutically active form, upon appropriate irradiation.
