Trade Names:Platinol AQ- Solution for injection 1 mg/mL- Powder for injection 1 mg/mL
The antitumor effect of cisplatin has been correlated with binding to DNA, production of intrastrand crosslinks, and formation of DNA adducts.
Vd is about 11 to 12 L/m 2 (steady state). Platinum is 90% protein bound. Cisplatin is excreted in breast milk.
The t ½ is about 20 to 30 min (cisplatin) and at least 5 days (platinum-albumin complexes). Cl is about 15 to 16 L/h/m 2 . Renal Cl is 50 to 62 mL/min/m 2 . Cisplatin is 90% excreted in urine and less than 10% removed by biliary excretion.
Metastatic testicular or ovarian tumors, advanced bladder cancer.
Squamous cell carcinoma of the head and neck and of the cervix; lung carcinomas, osteogenic sarcoma, brain tumors; advanced esophageal, adrenal cortex, breast, endometrial, and liver carcinoma, bone marrow transplantation.
Pre-existing renal impairment; myelosuppression; hearing impairment; history of allergic reactions to cisplatin or other platinum-containing compounds.
IV Cisplatin 20 mg/m 2 /day IV for 5 days every 3 wk for 3 courses (combination regimen). Single doses of cisplatin up to 120 mg/m 2 in combination with other antineoplastics have been used.Metastatic Ovarian Tumors (Cyclophosphamide Combination Therapy)Adults
IV Cisplatin 75 to 100 mg/m 2 once every 4 wk. Cyclophosphamide 600 mg/m 2 once every 4 wk (day 1).Metastatic Ovarian Tumors (Single Agent Therapy)Adults
IV Administer as a single agent of 100 mg/m 2 IV/cycle once every 4 wk.Advanced Bladder CancerAdults
IV Administer as a single agent. Give 50 to 70 mg/m 2 once every 3 to 4 wk, depending on prior radiation therapy or chemotherapy. For heavily pretreated patients, give an initial dose of 50 mg/m 2 /cycle repeated every 4 wk.Repeat CoursesAdults
IV Do not give a repeat course until serum creatinine is below 1.5 mg/dL or BUN is below 25 mg/dL or until circulating blood elements are at an acceptable level (platelets at least 100,000/mm 3 , WBC at least 4,000/mm 3 ). Do not give subsequent doses until an audiometric analysis indicates that auditory acuity is within normal limits.Renal ImpairmentAdults
IV The manufacturer does not recommend the use of cisplatin in patients with renal impairment. Some clinicians recommend not giving cisplatin to patients with a Ccr below 30 mL/min.
Potentiation of nephrotoxicity is possible.Lithium
Cisplatin may transiently decrease lithium serum levels.Loop diuretics (eg, furosemide)
Potentiation of ototoxicity is possible.Paclitaxel
Paclitaxel clearance decreases when cisplatin is given immediately prior to paclitaxel, resulting in increased hematologic toxicity.Phenytoin
Cisplatin may decrease absorption or increase metabolism, resulting in lower serum levels of phenytoin.
None well documented.
MI; cerebrovascular accident; cerebral arteritis; thrombotic microangiopathy.
Peripheral sensory neuropathy with a glove-and-stocking distribution.
Nausea; vomiting; anorexia; transient LFT elevations.
Bone marrow suppression.
Hypomagnesemia; hypocalcemia; hypokalemia; SIADH.
Dose-related and cumulative renal tubular damage.
Tinnitus; high frequency hearing loss.
WarningsOverdose/confusion with carboplatin
Doses above 100 mg/m 2 /cycle once every 3 to 4 wk rarely used. Avoid confusion with carboplatin or prescribing practices that fail to differentiate daily doses from total dose per cycle.GI
Marked nausea and vomiting occur in almost all patients and are occasionally so severe that the drug must be discontinued.Hematologic
Myelosuppression occurs in 25% to 30% of patients. Leukopenia and thrombocytopenia are more pronounced at doses above 50 mg/m 2 . Anemia (decrease of 2 g hemoglobin/dL) occur at the same frequency and with the same timing as leukopenia and thrombocytopenia.Hypersensitivity
Anaphylactic-like reactions have occurred.Ototoxicity
Has occurred in no more than 31% of patients given a single dose of 50 mg/m 2 . It is manifested by tinnitus or loss of high frequency hearing, and occasionally deafness. May be pronounced in children.Renal toxicity
Dose-related and cumulative renal insufficiency is the major dose-limiting toxicity. This is manifested by elevations in BUN and creatinine, serum uric acid, or a decrease in Ccr. Renal toxicity becomes more severe and prolonged with repeated courses; therefore, renal function must return to normal before another dose can be given. Amifostine can be used to reduce renal toxicity in patients with advanced ovarian cancer receiving repeated doses of cisplatin.
Category D .
Reported to be found in breast milk. Do not breast-feed.
Safety and efficacy not established.
Hypomagnesemia, hypocalcemia, hyponatremia, hypokalemia, and hypophosphatemia have occurred and are probably related to renal tubular damage.
Local irritation or phlebitis may occur. Refer to your institution specific protocol.
Transient elevations of liver enzymes, especially AST, as well as bilirubin have been reported.
Muscle cramps, defined as localized painful, involuntary skeletal muscle contractions of sudden onset and short duration, have occurred.
Occurs at about the same frequency as increase in BUN and serum creatinine. It is more pronounced after doses above 50 mg/m 2 . Monitor serum uric acid. Minimize effects with hydration, urinary alkalinization, and allopurinol.
Neurotoxicity, usually characterized by peripheral neuropathy, have occurred. Severe neuropathies have occurred in patients receiving higher doses of cisplatin or greater dose frequencies than those recommended, or after prolonged therapy. Discontinue therapy when symptoms are observed.
Optic neuritis, papilledema, and cerebral blindness have occurred infrequently in patients receiving recommended cisplatin doses.
These events are rare and coincident with the use of cisplatin in combination with other antineoplastic agents. These events may include MI, cerebrovascular accident, thrombotic microangiopathy, or cerebral arteritis.
Kidney failure, liver failure, deafness, ocular toxicity, significant myelosuppression, intractable nausea and vomiting, neuritis, death.
