The U.S. Food and Drug Administration (FDA) has approved its new drug application for Extina (R) (ketoconazole) Foam, 2% for the treatment of seborrheic dermatitis.

Different from other treatments for seborrheic dermatitis, which contain ketoconazole 2% in a cream, gel or shampoo vehicle, Extina is administered using VersaFoam(R) HF(R) (hydroethanolic formulation) technology, a unique, versatile topical drug delivery vehicle that is quickly absorbed into the skin. Extina Foam proved to be superior to placebo foam in a Phase III clinical trial. Of subjects receiving Extina (R) Foam, 56% achieved treatment success based on an Investigator Global Assessment compared to 42% of subjects receiving vehicle foam. Stiefel Laboratories, the world’s largest independent pharmaceutical company specializing in dermatology, acquired the proprietary VersaFoam HF technology with its December 2006 acquisition of Connetics Corporation.

Extina should be applied to the affected skin areas twice a day (morning and evening) for four weeks. Extina is administered via VersaFoam HF, which studies show offers consistent skin permeation, drug distribution and drug delivery. Additional patient benefits include versatility (Extina can be used on hair bearing and non hair-bearing skin), it absorbs quickly and it is non-drying with no residue.
