Excipients/Inactive Ingredients: Sodium chloride, Dilute hydrochloric acid, Water for injections.
Pharmacology: Pharmacodynamics: Antineoplastic agents, other antineoplastic agents, platinum compounds.
Cisplatin is an anorganic substance containing a heavy metal [cis-diamminedichloroplatinum(II)]. This substance inhibits the DNA synthesis by realising transverse connections within and between the DNA strings.
The protein and RNA synthesis is inhibited to a lesser extent.
Although the primary activity of cisplatin seems to be the inhibition of DNA synthesis, the antineoplastic process includes other activities, such as enlargement of the tumour immunogenicity. Cisplatin's oncolytic functions can be compared to the functions of alkylating substances. Cisplatin also offers immunosuppressive, radiosensitising and antibacterial features.
Cisplatin does not seem to be cell cycle specific.
The cytotoxic activities of cisplatin are caused by binding all DNA bases, with a preference for the N-7 position of guanine and adenosine.
Pharmacokinetics: After intravenous administration, cisplatin is rapidly distributed among all tissues. Following cisplatin doses of 20 to 120 mg/m2, the concentrations of platinum are highest in liver, prostate and kidney, somewhat lower in bladder, muscles, testicle, pancreas and spleen and lowest in bowel, adrenal, heart, lung, cerebrum and cerebellum. Over 90% of the total plasma cisplatin is bounded with protein after two hours following the administration. This process may be irreversible. The protein-bounded part is not antineoplastic active. Cisplatin is non-linearly pharmacokinetic.
Cisplatin is converted by a non-enzymatic process into one or more metabolites. Elimination from the plasma is realised in two phases after intravenous bolus injection of 50-100 mg/m2, of cisplatin.
The following half-life period have been registered for humans: t½ (distribution): 10-60 minutes; t½ (terminal): approximately 2-5 days.
The considerable protein binding of the total platinum contents results in an extended or incomplete excretion phase with cumulative urine secretion ranging from 27 to 45% of the administered dose in a period from 84 to 120 hours. An extended infusion results in the urine secretion of a larger part of the dose. The faecal secretion is minimal, and small amounts of platinum can be traced in the gallbladder and the large intestine. Dysfunctional kidneys increase the plasma half-life period, which may also increase theoretically in the presence of ascites caused by the highly protein binding activities of cisplatin.
Toxicology: Preclinical safety data: Chronic toxicity: Chronic toxicity models indicate kidney damage, bone marrow depression, gastrointestinal disorders and ototoxicity.
Mutagenicity and carcinogenicity: Cisplatin is mutagenic in numerous in vitro and in vivo tests (bacterial test systems and chromosome defects in animal cells and tissue cultures). Long-term studies of cisplatin on mice and rats evidenced the carcinogenic effects.
Reproductive toxicity: Fertility: Gonadal suppression resulting in amenorrhoea or azoospermia may be irreversible and cause definitive infertility.
Studies in rats showed that exposure during pregnancy produces tumours in the adult offspring.
Pregnancy and lactation: Cisplatin is embryotoxic and teratogenic for mice and rats, and defects have been reported for both species. Cisplatin was found in the milk.
To be used as mono-therapy, or as part of an existing chemotherapy for advanced or metastatic tumours: testicular carcinoma (palliative and curative poly-chemotherapy) and; ovary carcinoma (stages III and IV), and; head and neck squamous-cell epithelioma (palliative therapy).
In the treatment of small cell lung carcinoma.
In the treatment of advanced non-small cell lung carcinoma.
Dosage/Direction for Use
Cisplatin concentrate for solution for infusion is to be diluted before use (see Special precautions for disposal and other handling under Cautions for Usage).
The diluted solution should be administered only intravenously by infusion (see as follows).
For administration, any device containing aluminium that may come in contact with cisplatin (sets for intravenous infusion, needles, catheters, syringes) must be avoided (see Incompatibilities under Cautions for Usage).
Adults and children: The cisplatin dose depends on the primary disease, the expected reaction, and on whether cisplatin is used for monotherapy or as a component of a combination chemotherapy. The dose directions are applicable for both adults and children. For recommendations on the dose applicable, based on the diagnosis and the clinical condition, the current medical literature should be consulted.
For monotherapy, the following two dose regimens are recommended: Single dose of 50 to 120 mg/m2 body surface area every 3 to 4 weeks; 15 to 20 mg/m2/day for five days, every 3 to 4 weeks.
If cisplatin is used in combination chemotherapy, the dose of cisplatin must be reduced. A typical dose is 20 mg/m2 or more once every 3 to 4 weeks unless in the combination therapy of small-cell and non-small-cell lung carcinoma, in which a typical dose of 80 mg/m2 is administered.
Further dose recommendations are to be based upon current medical insights, to be obtained from the literature or/and the appropriate working parties.
For warnings and precautions to be considered prior to the start of the next treatment cycle, see Warnings and Precautions.
In patients with renal dysfunction or bone marrow depression, the dose should be reduced adequately.
The cisplatin solution for infusion prepared according to instructions (see Special precautions for disposal and other handling under Cautions for Usage) should be administered by intravenous infusion over a period of 6 to 8 hours.
Adequate hydration must be maintained from 2 to 12 hours prior to administration until minimum 6 hours after the administration of cisplatin.
Hydratation is necessary to cause sufficient diuresis during and after treatment with cisplatin. It is realised by intravenous infusion of one of the following solutions: Sodium chloride solution 0.9%; Mixture of sodium chloride solution 0.9% and glucose solution 5% (1:1).
Hydration prior to treatment with cisplatin: Intravenous infusion of 100 to 200 ml/hour for a period of 6 to 12 hours.
Hydration after termination of the administration of cisplatin: Intravenous infusion of another 2 litres at a rate of 100 to 200 ml per hour for a period of 6 to 12 hours.
Forced diuresis may be required should the urine secretion be less than 100 to 200 ml/hour after hydration. Forced diuresis may be realised by intravenously administering 37.5 g mannitol as a 10% solution (375 ml mannitol solution 10%), or by administration of a diuretic if the kidney functions are normal. The administration of mannitol or a diuretic is also required when the administrated cisplatin dose is higher than 60 mg/m2 of body surface.
It is necessary that the patient drinks large quantities of liquids for 24 hours after the cisplatin infusion to ensure adequate urine secretion.
Caution is essential in order to prevent an inadvertent overdose.
An acute overdose of cisplatin may result in renal failure, liver failure, deafness, ocular toxicity (including detachment of the retina), significant myelosuppression, untreatable nausea and vomiting and/or neuritis. An overdose may be fatal.
There is no specific antidote in the event of a cisplatin overdose. Even if hemodialysis is initiated 4 hours after the overdose it has little effect on the elimination of cisplatin from the body due to a strong and rapid fixation of cisplatin to proteins.
Treatment in the event of an overdose consists of general supportive measures.
Cisplatin may give allergic reactions in some patients. Use is contraindicated in those patients with a history of allergic reaction to cisplatin or other platinum containing compounds, or any component of the formulation.
Cisplatin induces nephrotoxicity which is cumulative. It is therefore contraindicated in patients with pre-existing renal impairment.
Cisplatin has also been shown to be cumulatively neurotoxic (in particular ototoxic) and should not be given to patients with pre-existing hearing impairment. Cisplatin is also contraindicated in myelosuppressed patients and those who are dehydrated.
Patients receiving cisplatin should not breastfeed.
Concurrent administration of yellow fever vaccine is contraindicated.
Combination with phenytoin in prophylactic use (see Interactions).
The cytostatic agent has a more marked toxicity than is usually found in antineoplastic chemotherapy.
Renal toxicity, which is above-all cumulative, is severe and requires particular precautions during administration (see Dosage & Administration and Adverse Reactions).
Nausea, vomiting and diarrhoea often occur after administration of cisplatin (see Adverse Reactions). These symptoms disappear in most patients after 24 hours. Less serious nausea and anorexia may continue up to seven days after the treatment.
Nausea and vomiting may be intense and require adequate antiemetic treatment.
Prophylactic administration of an anti-emetic may be effective in alleviating or preventing nausea and vomiting.
The liquid loss caused by vomiting and diarrhoea must be compensated.
Close supervision must also be carried out with regard to ototoxicity, myelodepression and anaphylactic reactions (see Adverse Reactions).
Cisplatin has been shown to be mutagenic. It may also have an anti-fertility effect. Other anti-neoplastic substances have been shown to be carcinogenic and this possibility should be borne in mind in long term use of cisplatin.
Preparation of the intravenous solution: As with all other potentially toxic products, precautions are essential when handling the cisplatin solution. Skin lesions are possible in the event of accidental exposure to the product. It is advisable to wear gloves. In the event the cisplatin solution comes into contact with the skin or mucous membranes, wash the skin or mucous membranes vigorously with soap and water.
Conforming to the procedures appropriate for the manipulation and elimination of cytostatic agents is recommended.
Before administering the solution to the patient, verify the clarity of the solution and the absence of particles.
Special Precautions
Cisplatin reacts with metallic aluminium to form a black precipitate of platinum. All aluminium containing IV sets, needles, catheters and syringes should be avoided.
Cisplatin must be administered under close supervision by a qualified doctor specialised in the use of chemotherapeutic agents.
Appropriate monitoring and management of the treatment and its complications are only possible if adequate diagnosis and exact treatment conditions are available.
Before, during and after administration of cisplatin, the following parameters resp. organ functions must be determined: renal function; hepatic function; haematopoiesis functions (number of red and white blood cells and blood platelets); serum electrolytes (calcium, sodium, potassium, magnesium).
These examinations must be repeated every week over the entire duration of the treatment with cisplatin.
Repeating administration of cisplatin must be delayed until normal values are achieved for the following parameters: serum creatinine ≤130 μmol/l rsp. 1.5 mg/dl; urea <25 mg/dl; white blood cells >4.000/μl resp. >4.0 x 109/l; blood platelets >100.000/μl resp. >100 x 109/l; audiogram: results within the normal range.
Nephrotoxicity: Cisplatin produces severe cumulative nephrotoxicity which may be potentiated by aminoglycoside antibiotics.
A urine output of 100 ml/hour or greater will tend to minimise cisplatin nephrotoxicity. This can be accomplished by prehydration with 2 litres of an appropriate intravenous solution, and similar post cisplatin hydration (recommended 2,500 ml/m2/24 hours). If vigorous hydration is insufficient to maintain adequate urinary output, an osmotic diuretic may be administered (e.g., mannitol).
Neuropathies: Severe cases of neuropathies have been reported.
These neuropathies may be irreversible and may manifest by paraesthesia, areflexia and a proprioceptive loss and a sensation of vibrations. A loss of motor function has also been reported. A neurologic examination must be carried out at regular intervals.
Ototoxicity: Ototoxicity has been observed in up to 31% of patients treated with a single dose of cisplatin 50mg/m2, and is manifested by tinnitus and/or hearing loss in the high frequency range (4000 to 8000Hz). Decreased ability to hear conversational tones may occur occasionally. Ototoxic effect may be more pronounced in children receiving cisplatin. Hearing loss can be unilateral or bilateral and tends to become more frequent and severe with repeated doses; however, deafness after initial dose of cisplatin has been reported rarely. Ototoxicity may be enhanced with prior simultaneous cranial irradiation and may be related to peak plasma concentration of cisplatin. It is unclear whether cisplatin induced ototoxicity is reversible. Careful monitoring by audiometry should be performed prior to initiation of therapy and prior to subsequent doses of cisplatin. Vestibular toxicity has also been reported (see Adverse Reactions).
Allergic phenomena: As with other platinum-based products, hypersensitivity reactions appearing in most cases during perfusion may occur, and necessitate discontinuation of the perfusion and an appropriate symptomatic treatment. Cross reactions, sometimes fatal, have been reported with all the platinum compounds (see Contraindications and Adverse Reactions).
Hepatic function and haematological formula: The haematological formula and the hepatic function must be monitored at regular intervals.
Carcinogenic potential: In humans, in rare cases the appearance of acute leukaemia has coincided with use of cisplatin, which was in general associated with other leukaemogenic agents.
Cisplatin is a bacterial mutagen and causes chromosome aberrations in cultures on animal cells. Carcinogenicity is possible but has not been demonstrated. Cisplatin is teratogenic and embryotoxic in mice.
Injection site reactions: Injection site reactions may occur during the administration of cisplatin. Given the possibility of extravasation, it is recommended to closely monitor the infusion site for possible infiltration during medicinal product administration. A specific treatment for extravasation reactions is unknown at this time.
The safe use of product in latex-sensitive individuals has not been studied.
Effects on ability to drive and use machines: No studies on the effects on ability to drive and use machines have been performed. Nevertheless, the profile of undesirable effects (like nephrotoxicity) may influence the ability to drive vehicles and use machinery.
Patients who suffer from these effects (e.g. sleepy or vomiting) must avoid driving and operating machinery.
Use In Pregnancy & Lactation
Pregnancy: Cisplatin may be toxic to the fetus when administered to a pregnant woman.
Cisplatin should not be used during pregnancy unless clearly necessary.
During treatment with cisplatin and for a minimum of the following 6 months, appropriate measures must be taken to avoid pregnancy; this applies to patients of both genders.
Genetic counseling is recommended if the patient wishes to have children after ending the treatment.
Since a treatment with cisplatin may cause irreversible infertility, it is recommended that men, who wish to become fathers in the future, ask for advice regarding cryo-conservation of their sperm prior to treatment.
Breast-feeding: Cisplatin is excreted in breast milk. Patients treated with cisplatin must not breastfeed.
Adverse Reactions
The most frequently reported adverse events (>10%) of cisplatin were hematological (leukopenia, thrombocytopenia and anemia), gastrointestinal (anorexia, nausea, vomiting and diarrhea), ear disorders (hearing impairment), renal disorders (renal failure, nephrotoxicity, hyperuricemia) and fever.
Serious toxic effects on the kidneys, bone marrow and ears have been reported in up to about one third of patients given a single dose of cisplatin; the effects are generally dose-related and cumulative. Ototoxicity may be more severe in children.

Drug Interactions
Nephrotoxic substances: Concomitant administration of nephrotoxic (e.g. cephalosporins, aminoglycosides, amphotericin B or contrast media) or ototoxic (e.g. aminoglycosides) medicinal products will potentiate the toxic effect of cisplatin on the kidneys. During or after treatment with cisplatin caution is advised with predominantly renally eliminated substances, e.g. cytostatic agents such as bleomycin and methotrexate, because of potentially reduced renal elimination.
The renal toxicity of ifosfamide may be greater when used with cisplatin or in patients who have previously been given cisplatin.
Reduction of the blood's lithium values was noticed in a few cases after treatment with cisplatin combined with bleomycin and etoposide. It is therefore recommended to monitor the lithium values.
The occurrence of nephrotoxicity caused by cisplatin may be intensified by concomitant treatment with antihypertensives containing furosemide, hydralazine, diazoxide, and propranolol.
It may be required to adjust the dose of allopurinol, colchicine, probenecid, or sulfinpyrazone if used together with cisplatin, since cisplatin causes an increase in serum uric acid concentration.
Simultaneous use of ifosfamide causes increased protein excretion.
Ototoxic substances: Concomitant administration of ototoxic (e.g. aminoglycosides, loop diuretics) medicinal products will potentiate the toxic effect of cisplatin on auditory function. Except for patients receiving doses of cisplatin exceeding 60 mg/m2, whose urine secretion is less than 1000 ml per 24 hours, no forced diuresis with loop diuretics should be applied in view of possible damage to the kidney tract and ototoxicity.
Ifosfamide may increase hearing loss due to cisplatin.
Attenuated live vaccines: Yellow fever vaccine is strictly contraindicated because of the risk of fatal systemic vaccinal disease (see Contraindications). In view of the risk of generalised illness, it is advisable to use an inactive vaccine if available.
Use of living virus vaccinations is not recommended given within three months following the end of cisplatin treatment.
Oral anticoagulants: In the event of simultaneous use of oral anticoagulants, it is advisable regularly to check the INR.
Antihistamines, phenothiazines and others: Simultaneous use of antihistamines, buclizine, cyclizine, loxapine, meclozine, phenothiazines, thioxanthenes or trimethobenzamides may mask ototoxicity symptoms (such as dizziness and tinnitus).
Anticonvulsive substances: Serum concentrations of anticonvulsive medicines may remain at sub-therapeutic levels during treatment with cisplatin.
Cisplatin may reduce the absorption of phenytoin resulting in reduced epilepsy control when phenytoin is given as current treatment. During cisplatin therapy starting a new anticonvulsant treatment with phenytoin is strictly contraindicated (see Contraindications).
Pyridoxine + altretamine combination: During a randomised study of the treatment of advanced ovarian cancer, the response time was unfavorably affected when pyridoxine was used in combination with altretamine (hexamethylmelamine) and cisplatin.
Paclitaxel: Treatment with cisplatin prior to an infusion with paclitaxel may reduce the clearance of paclitaxel by 33% and therefore can intensify neurotoxicity.
Other: Simultaneous use of myelosuppressives or radiation will boost the effects of cisplatin's myelosuppressive activity.
Cisplatin given in combination with bleomycin and vinblastine can lead to a Raynaud-phenomenon.
In a study of cancer patients with metastatic or advanced tumors, docetaxel in combination with cisplatin induced more severe neurotoxic effects (dose-related and sensoric) than either drug as a single agent in similar doses.
Chelating agents like penicillamine may diminish the effectiveness of cisplatin.
In concomitant use of cisplatin and ciclosporin the excessive immunosuppression with risk of lymphoproliferation is to be taken into consideration.
Caution For Usage
Special precautions for disposal and other handling: Cisplatin concentrate for solution for infusion is to be diluted before use.
