Device For Administering Bimakalim Transdermally
View pageUS Patent:
52467066, Sep 21, 1993
Filed:
Jul 19, 1991
Appl. No.:
7/733729
Inventors:
Chia-Ming Chiang - Foster City CA
Tung F. Chen - Redwood City CA
Tung F. Chen - Redwood City CA
Assignee:
Cygnus Therapeutic Systems - Redwood City CA
International Classification:
A61F 1300
US Classification:
424449
Abstract:
Multi-day skin patches for administering bimakalim transdermally to treat cardiovascular diseases are described which consist of laminated composites having an occlusive elastomeric polymer backing layer and an underlying reservoir layer composed of a solid matrix of bimakalim dispersed in a polydimethylsiloxane or acrylate adhesive. The skin flux of bimakalin from the patches is greater than 0. 1. mu. g/cm. sup. 2 /hr.

A61M 3700
US Classification:
424484
Abstract:
A two-phase hydrophilic drug-containing matrix for use in transdermal drug delivery patches in which one phase is a continuous hydrophobic polymer phase which optionally includes a hydrophobic solvent that acts as a skin permeation enhancer and the other phase is a dispersed particulate hydrated inorganic silicate in whose absorbed aqueous phase the drug is dissolved.
