Abstract
Methods and compositions for enhancing transdermal delivery of a bioactive agent. The method contains the step of applying to a skin tissue an effective amount of a composition comprising: (a) a drug vehicle; (b) a bioactive agent encapsulated within the drug vehicle; (c) a plurality of proteolytic enzyme molecules conjugated onto the surface of the drug vehicle; and (d) a pharmaceutically acceptable carrier, for a period of time effective to deliver the bioactive agent across the skin tissue at a desired dosage.
