  • Iontotherapeutic device and process and iontotherapeutic unit dose
    Patent number: 5961482
    Abstract: This invention relates to development of an iontotherapeutic device for regulated transdermal systemic administration of ionizable pharmaceutical compounds. It also provides an iontotherapeutic process for transdermal administration of ionized pharmaceuticals, particularly those which are otherwise transdermally absorbed to a small degree or not all, such as peptide pharmaceuticals, for example, insulins. The invention also relates to unit dose forms, for example, those in which an ionized pharmaceutical is dispersed in a hydrophilic polymer. The unit dose is adapted to be assembled as part of the pharmaceutical reservoir electrode, so that the ionized pharmaceutical will be delivered transdermally and then be absorbed systemically when the iontotherapeutic device is in operation.
    Type: Grant
    Filed: March 19, 1996
    Date of Patent: October 5, 1999
    Assignee: Rutgers, The State University Of New Jersey
    Inventors: Yie W. Chien, John Kong-Jiann Li, Jue-Chen Liu, Wei-Min Shi, Ovais Siddiqui, Ying Sun
