Description
Cordran Tape (Flurandrenolide Tape, USP) is a transparent, inconspicuous, plastic surgical tape. It contains Cordran (Flurandrenolide, USP), a potent corticosteroid for topical use. Flurandrenolide occurs as white to off-white, fluffy crystalline powder and is odorless. Flurandrenolide is practically insoluble in water and in ether. One g dissolves in 72 mL of alcohol and in 10 mL of chloroform. The molecular weight of flurandrenolide is 436.52.
The chemical name of flurandrenolide is Pregn-4-ene-3,20-dione, 6-fluoro-11,21 dihydroxy-16,17-[(1-methylethylidene)bis(oxy)]-, (6α, 11ß, 16α)-; its empirical formula is C24H33FO6. The structural formula is as follows:
Each square centimeter contains 4 μg (0.00916 μmol) flurandrenolide uniformly distributed in the adhesive layer. The tape is made of a thin, matte-finish polyethylene film that is slightly elastic and highly flexible.
The adhesive is a synthetic copolymer of acrylate ester and acrylic acid that is free from substances of plant origin. The pressure-sensitive adhesive surface is covered with a protective paper liner to permit handling and trimming before application.
