  • Publication number: 20100331812
    Abstract: The present invention describes pharmaceutical formulations and methods suitable for iontophoretic delivery of the formulations to a subject. The formulations comprise an immunomodulator, such as imiquimod, and optionally include various agents and excipients. The formulations can be used as a treatment for skin diseases and conditions such as actinic keratosis, basal cell carcinoma and genital warts. The short term iontophoretic delivery of the formulations results in the creation of a depot effect in the skin of the subject, allowing for a sustained delivery. The shortened delivery time minimizes local side effects at the application site.

  • Patent number: 6329508
    Abstract: The present invention pertains to chimeric antibodies that are reactive with transferrin receptors on brain capillary endothelial cells. These antibodies are composed of a variable region, immunologically reactive with the transferrin receptors, that is obtained from one animal source, and a constant region that is derived from an animal source other than the one that provided the variable region. These chimeric antibodies can exist either as isolated entities or as conjugates with a neuropharmaceutical agent for transferal across the blood brain barrier.

  • Patent number: 6153210
    Abstract: Periodontal disease can be treated by the administration of metal ions, preferably silver ions, to the site where the microorganisms that cause this disease reside. Administration can be to periodontal pockets or adjacent to exposed tooth roots or alveolar bone during periodontal surgical procedures. The metal ions can be administered in polymeric microparticles, deformable films or microparticles embedded within deformable films. The metal ions are particularly microbiocidal to the bacterial pathogens that are the causative agents of periodontal disease.
