What is Anthralin

Anthralin (also known as dithranol) is a synthetic topical antipsoriatic agent and a derivative of anthracene.

It is used for quiescent or chronic psoriasis. Anthralin also may be used for alopecia, although it is not FDA-approved for this indication.

Do not apply to face, genitalia, eyes, open sores, or mucous membranes because painful irritation can occur.

Protective dressings to shield unaffected skin are recommended.

This agent can stain fabric, skin, or hair with a yellow-brown color; stains can be permanent.

Anthralin was initially marketed for use before 1962, which is when Congress passed the amended Federal Food, Drug, and Cosmetic Act requiring that the FDA establish both safety and efficacy for all subsequently approved drugs.

Anthralin products are unapproved marketed drugs that have not been formally evaluated by the FDA.
