    摘要: This invention is directed to a novel formulation for effectively utilizing hydrophobic permeation enhancers for the increased permeability of active agents through the skin or mucosa along with reduction of the lag time between application of the active agent and attainment of a therapeutically effective agent flux, with little or no irritation to the host. The invention is directed to compositions containing a hydrophobic permeation enhancer, which permeation enhancer has been micronized and stabilized in an inert carrier such as water. These compositions can be combined with a biologically active agent to provide enhanced permeability of the active agent to the skin or mucosa.

    摘要: Transdermal compositions, devices, and methods for the administration of a drug at reduced skin irritation levels are disclosed. More particularly, this invention relates to novel methods, compositions, and devices for the reduction or elimination of irritation or sensitization caused by an irritating or sensitizing drug when it is delivered transdermally. According to a preferred embodiment, transdermal administration of a drug salt of a non-zwitterionic drug is disclosed wherein the drug salt comprises a combination of surface activity and a low octanol-water partition coefficient. Such drug salts have been found to reduce irritation or sensitization to the drug being delivered while achieving therapeutically effective transdermal fluxes.

    摘要: An electrotransport delivery device utilizing reservoir buffering at a select pH ranges in order to reduce skin irritation and skin resistance is provided. Cathodic reservoirs are buffered to a pH of less than about 4, preferably to a pH in the range of about 2 to 4, while anodic reservoirs are buffered to a pH above about 4, preferably to a pH in the range of about 4 to 10. Another electrotransport delivery device utilizes a potassium sensor to monitor potassium efflux from the skin. Potassium efflux above a certain predetermined level has been found to be a precursor to skin irritation/erythema. Operation of the device is modified (eg, terminated) when the predetermined potassium efflux level is sensed.
