  • Publication number: 20220226159
    Abstract: A layered composite for scar treatment and prevention, the layered composite including a backing section; a drug matrix section; and a skin-interfacing section. The drug matrix section may be disposed between the back section and the skin-interfacing section. The drug matrix section may include pirfenidone in an amount of from about 1 to about 20 mg/cm2. The layered composite may provide greater than about 75% release of the pirfenidone over a period of about 48 to 72 hours. A method for scar treatment and prevention that includes applying a layered composite as described to a burn wound.
