FDA Approves Differin OTC Acne Drug
FDA has approved Galderma Laboratories’ Differin Gel 0.1% (adapalene), a once-daily topical gel for over-the-counter treatment of acne in people age 12 and older. An agency statement says Differin Gel is the first retinoid to be made available OTC for treating acne. FDA also says the gel contains the first new active ingredient for acne treatment for OTC use since the 1980s. Differin Gel was originally approved in 1996 as a prescription product for treating acne vulgaris in patients age 12 and older.
The statement says that the drug’s safety and efficacy were initially established based on five clinical trials in people with mild to moderate acne. To support approval for the OTC switch, data accrued from 1996 to 2016 on post-marketing safety, data from consumer studies, and data from a maximal use trial were submitted. Results from the consumer studies, FDA says, showed that consumers can understand the information on the OTC label, appropriately select whether the product is right for them, and use the product appropriately. The maximal use trial reportedly demonstrated that absorption is limited, thus supporting safe OTC use of the product.
