Summary

Cisplatin, carboplatin, and oxaliplatin are all platinum-containing drugs that function as chemotherapeutics by crosslinking DNA via their platinum atoms. They are useful in the treatment of solid tumors, but patients taking these drugs can experience nephrotoxicity, including Fanconi syndrome, which can be prevented with the administration of amifostine. Other side effects to note include ototoxicity and peripheral neuropathy.

Key Points

  • Platinum Analogs (cisplatin, carboplatin, oxaliplatin)
    • Mechanism
      • Crosslinks DNA
    • Clinical use
