Filed:

Oct 13, 2000

Appl. No.:

09/687937

Inventors:

Eric C. Luo - Plano TX
Eric C. Jacobson - San Diego CA
Tsung-Min Hsu - San Diego CA

Assignee:

Dermatrends, Inc. - San Diego CA

International Classification:

A61F 1300

US Classification:

424449, 424443, 424445, 424447, 424448, 514946, 514947, 514944

Abstract:

A method is provided for increasing the permeability of skin or mucosal tissue to a topically or transdermally administered pharmacologically or cosmeceutically active peptide, polypeptide or protein. The method involves use of a specified amount of a hydroxide-releasing agent, the amount optimized to increase the flux of the peptide, polypeptide or protein through a body surface while minimizing the likelihood of skin damage, irritation or sensitization. Formulations and drug delivery devices employing hydroxide-releasing agents as permeation enhancers are provided as well.

Abstract:

A permeation enhancer composition is provided for increasing the permeability of skin or mucosal tissue to topically or transdermally administered pharmacologically or cosmeceutically active agents. The composition is comprised of a hydroxide-releasing agent and a lipophilic co-enhancer such as a fatty alcohol, a fatty ether, or a fatty acid ester, including fatty acid esters of polyols such as propylene glycol and glycerol. Also provided are pharmaceutical formulations containing a therapeutically effective amount of an active agent in addition to the aforementioned enhancer composition, methods for administering active agents topically or transdermally with enhanced permeation, and drug delivery systems for application to an individuals skin or mucosal tissue, wherein the systems are formulated so as to contain an active agent to be administered and an effective permeation enhancing amount of an enhancer composition of the invention.
