cyclophosphamide + doxorubicin + fluorouracil + methotrexate + paclitaxel

This is a combination chemotherapy regimen containing five anticancer drugs that work through different mechanisms to treat cancer. Cyclophosphamide is an alkylating agent that stops cancer cells from reproducing. Doxorubicin (also known as Adriamycin) is an anthracycline antibiotic that interferes with DNA replication. Fluorouracil (5-FU) is an antimetabolite that stops cells from making and repairing DNA. Methotrexate is another antimetabolite that inhibits DNA synthesis. Paclitaxel is a taxane that disrupts microtubule function during cell division. This specific five-drug combination is not commonly documented in standard regimens, though various combinations of these drugs are used in breast cancer treatment protocols.
