Actikerall is a topical medication prescribed for the treatment of actinic keratosis, a condition characterized by rough, scaly patches on the skin caused by long-term exposure to the sun. The active ingredients in Actikerall are fluorouracil and salicylic acid. Fluorouracil belongs to a class of medications known as antineoplastics, which work by inhibiting the growth of abnormal cells that could lead to skin cancer. Salicylic acid aids in softening and removing the outer layer of the skin, allowing fluorouracil to penetrate more effectively. Actikerall is typically applied as a solution directly to the affected areas of the skin, providing a targeted treatment that helps to reduce the lesions associated with actinic keratosis.
