US Patent:

58114653, Sep 22, 1998

Filed:

Dec 5, 1997

Appl. No.:

8/985542

Inventors:

James A. Huntington - Chicago IL
Michel Cormier - Mountain View CA

Assignee:

Alza Corporation - Palo Alto CA

International Classification:

A61K 3108

US Classification:

514772

Abstract:

An electrotransport drug-containing composition is provided. The composition includes a drug to be delivered through a body surface (eg, skin) of a patient, and a permeation enhancer which is solid or semisolid at temperatures typically encountered during storage of pharmaceuticals (eg, temperatures up to at least about 25. degree. C). The composition of the invention may be applied from a device 10 suitable for electrotransport delivery. A method for increasing electrotransport agent delivery rate and reducing body surface resistance relies on applying the composition of the invention to the body surface, and applying an electric current through the composition and the body surface.

International Classification:

A61N 130
A61B 1000
A61K 31045
A61K 3107
A61K 4700

US Classification:

604 20

Abstract:

An electrotransport composition comprises at least one C. sub. 2 -C. sub. 4 lower alcohol, unsaturated derivatives thereof, or mixtures thereof, and at least one C. sub. 8 -C. sub. 4 higher alcohol, unsaturated derivatives thereof, or mixtures thereof. An electrotransport device and a method of increasing transdermal electrotransport flux utilize the composition of the invention for delivering pharmaceutically-acceptable agents across a body surface such as skin.
