Abstract
Compositions suitable for the treatment of acne by topical application comprise clindamycin and benzoyl peroxide. Kits for preparing the compositions include a solution of clindamycin in a first container and a gel suspension of benzoyl peroxide in a second container. Each component is stored at a pH which promotes stability, and the combination of the two components provides a final composition having a pH which promotes stability and enhances viscosity.
