Tretinoin/benzoyl peroxide

Tretinoin/Benzoyl Peroxide is a combination medication used in the treatment of acne. It contains two active ingredients: tretinoin, a retinoid, and benzoyl peroxide, an antimicrobial.

Etymology

The term "tretinoin" is derived from "retinoid", which refers to a group of compounds that are chemically related to vitamin A, also known as retinol. The term "benzoyl peroxide" is derived from its chemical structure, which consists of two benzoyl groups bridged by a peroxide link.

Pharmacology

Tretinoin works by increasing the turnover of skin cells, which aids in the exfoliation of the skin. This helps to unclog pores and prevent the formation of acne lesions. Benzoyl peroxide has an antimicrobial effect, which reduces the amount of acne-causing bacteria on the skin. It also has a mild drying effect, which allows excess oils and dirt to be easily washed away.

Uses

Tretinoin/benzoyl peroxide is used to treat acne vulgaris. It may be used in combination with other acne treatments. When applied to the skin, it can help reduce the number of acne blemishes and promote quick healing of pimples that do develop.

Side Effects

Common side effects of tretinoin/benzoyl peroxide include skin irritation, dryness, and peeling. These side effects are usually mild and improve over time with continued use of the medication. If these side effects persist or worsen, the patient should consult their healthcare provider.
