Abstract
Fluorouracil is an antimetabolite chemotherapeutic agent that inhibits the synthesis of thymine, a critical building block of DNA. Fluorouracil is preferentially incorporated into the DNA of cancers of the bone marrow, intestine, liver, and other tissues and leads to cell death. It is used systemically to treat cancers of the colon, head and neck, pancreas, and other organs.1-5
