For the treatment of Acne vulgaris in patients 12 and older.
Adapalene 0.1%, benzoyl peroxide 2.5% gel
Echo Torre Lazur
Epiduo Gel 0.1% / 2.5% is the first and only topical acne medication that combines a retinoid and benzoyl peroxide—and targets three out of the four causes of acne in a single product. The two treatments that make up Epiduo Gel include the well-tolerated retinoid adapalene, and benzoyl peroxide, a well-known antimicrobial. Clinical studies demonstrate that Epiduo Gel works better than adapalene 0.1% or benzoyl peroxide 2.5% used alone and significantly reduces acne. Galderma plans to promote these treatments to a variety of audiences.
Combination products, which offer greater convenience than multi-drug regimens, as well as the potential for lower copays, are increasingly favored for acne treatment. Galderma's Epiduo gel (adapalene) plus benzoyl peroxide) combines two standard acne treatments in a once daily formulation. With patient compliance an unmet need, physicians are likely to be receptive to this new alternative.

Epiduo is a topical acne treatment that combines adapalene with benzoyl peroxide. Adapalene is a naphthoic acid derivative with retinoid-like properties that binds to specific retinoic acid nuclear receptors resulting in modulation of cellular differentiation, keratinization, and inflammation. Benzoyl peroxide is a highly lipophilic oxidizing agent that localizes in bacterial and keratinocyte cell membranes to exert bactericidal and keratolytic effects.
Epiduo was evaluated in two 12-week, multicenter, controlled clinical studies of similar design. At baseline, patients in both studies had between 20–50 inflammatory lesions and 30–100 noninflammatory lesions. Treatment response was defined as the percent of patients who had a two grade improvement and rated “Clear” and “Almost Clear” at week 12 based on the Investigator's Global Assessment (IGA) and mean absolute change from baseline at week 12 in both inflammatory and non-inflammatory lesion counts. In both studies, patients were randomized to one of four treatment groups: Epiduo, adapalene 0.1% monotherapy, benzoyl peroxide 2.5% monotherapy or vehicle gel. A greater reduction in the median number of total acne lesions was seen in the Epiduo groups compared to the other three treatment groups. Also, the percent of patients who had a two grade improvement and rated “Clear” or “Almost Clear” on the IGA was greater in the Epiduo groups compared to the other three treatment groups.
