About

The purpose of this study is to determine whether Clindamycin Phosphate 1.2% And Tretinoin 0.025% Gel are effective and safe in the treatment of papulopustular rosacea.

Full description

Currently, there is no known cure for rosacea. The most effective treatment is systemic antibiotics, particularly of the tetracycline family. Topical treatments include metronidazole, antibacterials such as erythromycin and clindamycin, sulfacetamide and benzoyl peroxide. Isotretinoin (Accutane) is also used.
