Etoposide is a chemotherapy medication commonly used in the treatment of various cancers, including lung cancer, testicular cancer, and certain types of leukemia and lymphomas. It belongs to the class of drugs known as topoisomerase inhibitors. Etoposide works by inhibiting the enzyme topoisomerase II, which plays a crucial role in DNA replication and repair. By preventing topoisomerase II from sealing breaks in DNA strands, etoposide induces breaks and damages DNA, leading to the death of rapidly dividing cancer cells. Etoposide is often used as part of combination chemotherapy regimens to enhance its effectiveness against different types of cancers.
