Non-Teratogenic Vitamin A Preparation For Women Of Child-Bearing Age

View page

US Patent:

50617230, Oct 29, 1991

Filed:

May 22, 1989

Appl. No.:

7/355779

Inventors:

Arun B. Barua - Ames IA
Desiree Gunning - Ames IA
James A. Olson - Ames IA

Assignee:

Iowa State University Research Foundation, Inc. - Ames IA

International Classification:

H61K 3135

US Classification:

514460

Abstract:

For treatment of acne the glucuronide of retinoic acid (retinoyl. beta. -glucuronide) is orally administered to women of child-bearing age who are capable of conception. This therapy is safer than the oral administration of retinoic acid because retinoic acid glucuronide is essentially non-teratogenic at dose levels effective for the acne treatment. The retinoic acid glucuronide can be in all-trans or 13-cis form.
