Medication for treatment of acne should be effective but limited in order to avoid unnecessary adverse
effects. Treatment is directed at modification of one or more of four primary factors that promote the
development of acne. These factors include follicular hyperproliferation and abnormal desquamation;
increased sebum production; Proionbacterium acnes proliferation; and inammation. Therapies include
topical retinoids, azelaic acid, salicylic acid, hormonal therapy, benzoyl peroxide, topical and oral
antibiotics, and oral isotretinoin. The patient described in this case has moderate acne. Treatment of
moderate papulopustular and mixed acne includes topical retinoid plus oral antibiotic plus topical
benzoyl peroxide. With respect to interaction between benzyl peroxide and tretinoin, tretinoin and BP
should not be applied simultaneously to the skin due to the oxidizing effect of BP on tretinoin. If both
agents are prescribed, benzoyl peroxide should be applied in the morning and tretinoin in the evening.
Adapalene, the microsphere formulation of tretinoin, is stable in presence of BP.
