Acnecide
Acnecide Uses, Dosage, Side Effects, Food Interaction and all others data.
Benzoyl peroxide has mild keratolytic effect and antimicrobial activity due to release of free-radical oxygen which oxidizes bacterial protein. It is active against Staphylococcus epidermidis and Propionibacterium acnes.
Benzoyl peroxide is a topical treatment for acne that generates free radicals to break down comedones and increase the rate of epithelial cell turnover. It has a short duration of action as its active free radical metabolites quickly react to form inactive metabolites. The therapeutic index is wide, as overdoses are rare, however patients may still experience skin peeling. Patients should be counselled regarding increased risks of skin irritation, dryness, and sunburn.

Uses
Topical therapy for the treatment of acne vulgaris.
Acnecide is also used to associated treatment for these conditions: Acne, Acne Vulgaris, Inflammatory Acne Vulgaris
How Acnecide works
Acne vulgaris is caused by inflammation in the pilosebaceous gland. Acne is generally caused by increased excretion of sebum from pilosebaceous glands, endocrine factors such as androgenic hormones, keratin developing around follicles, bacterial growth, and inflammation. These factors contribute to the formation of comedones (whiteheads and blackheads).
The peroxide bond of benzoyl peroxide is cleaved to form 2 benzoyloxy radicals. These radicals interact nonspecifically with bacterial proteins, interfering with their function, and survival of the bacteria. Over time, free radical interactions with bacterial proteins lead to decreased keratin and sebum around follicles.
Benzoyl peroxide can also increase the turnover rate of epithelial cells, leading to skin peeling, and breaking down comedones.

In a sample of excised skin, 1.9% of a radiolabelled topical dose fully penetrates the skin, and 2.6% remains in the skin. The radiolabelled dose that fully penetrates the skin is recovered as benzoic acid, while the dose in the skin is approximately half benzoic acid and half benzoyl peroxide. 95.5% of a radiolabelled dose is not absorbed or metabolized after 8 hours.
Elimination Route
Benzoyl peroxide's metabolite benzoic acid, is eliminated in the urine. Data regarding fecal elimination is not readily available.
Pregnancy & Breastfeeding use
Pregnancy Category C. Either studies in animals have revealed adverse effects on the fetus (teratogenic or embryocidal or other) and there are no controlled studies in women or studies in women and animals are not available. Drugs should be given only if the potential benefit justifies the potential risk to the fetus.
