Contraindication Notes:
Cisplatin is contraindicated in patients with pre-existing renal impairment. Cisplatin should not be employed in myelosuppressed patients, or patients with hearing impairment. It is also contraindicated in patients with a history of allergic reactions to cisplatin or other platinum-containing compounds.
Cisplatin modifies cell cycle by interfering with DNA structure and function. Effects are most prominent during the S phase but cells are killed at all stages. Cisplatin synergises with other anticancer drugs e.g. fluorouracil. It has a narrow therapeutic margin and is highly toxic.
Synergistic with 5-fluorouracil and etoposide. Efficacy increased and toxicity reduced when combined with radioprotecting agent WR 2721. At doses ≤100 mg, cisplatin is an ideal drug to combine with other cytotoxic drugs; unlike other antineoplastic drugs, it causes little myelosuppression.
Severe nausea and vomiting. Serious toxic effects on the kidneys, bone marrows and ears. Hypomagnesaemia, hypocalcaemia, hyperuricaemia. Peripheral neuropathies, papilloedema, optic neuritis, seizures. Ototoxicity (children) manifested as tinnitus, loss of hearing, deafness or vestibular toxicity.
Acute overdosage may result in kidney failure, liver failure, deafness, ocular toxicity, significant myelosuppression, intractable nausea and vomiting and/or neuritis. Death may also occur following overdosage. Treatment should include general supportive measures.
Pregnancy Category D. There is positive evidence of human foetal risk, but the benefits from use in pregnant women may be acceptable despite the risk (e.g., if the drug is needed in a life-threatening situation or for a serious disease for which safer drugs cannot be used or are ineffective).
Patients with renal or hepatic disorder, myelosuppression. Monitor renal, neurological and auditory function. Perform blood counts regularly. Maintain adequate hydration before and 24 hr after admin to minimise nephrotoxicity.
