Carboplatin is primarily used in chemotherapy to treat various types of cancer. It is especially effective in treating ovarian cancer and is often used when initial treatments have failed or when patients cannot tolerate other drugs like cisplatin. Due to its mechanism of action—damaging cancer cell DNA to prevent replication—it is also used in the treatment of lung cancer, head and neck cancers, and certain types of brain tumors. Carboplatin is often combined with other chemotherapy agents, such as paclitaxel, to enhance its effectiveness. Its relatively predictable side effect profile and lower risk of kidney damage compared to similar drugs make it a preferred option in many treatment regimens, particularly for patients with compromised health.
