Cisplatin

Cisplatin is an antineoplatsic drug. Cisplatin is inorganic metal complex with a planar configuration discovered by Rosenderg and his cholleagues. Only the cis isomer of Cisplatin is active. Cisplatin is effective in the treatment of different cancers to slow or stop the growth of abnormal or cancerous cells. Cisplatin is used in the treatment of metastatic testicular and ovarian tumours. Cisplatin is used in combination with different anticancerous drugs to obtain best therapeutic effects and to minimize side effects or toxicities.

Effects

Interactions
Cisplatin is known to interact with other drugs, the details of drug interactions is as follows:DrugDetailsSeverityOnsetManagementAmikacin (Sulphate)Amphotericin BBleomycinIncreased pulmonary toxicity when Bleomycin given with Cisplatin.Cisplatin reduces renal elimination of Bleomycin and increases drug toxicity.CapreomycinIncreased risk of nephrotoxicity and ototoxicity when capreomycin given with platinum compounds (e.g Cisplatin).CetuximabDiazoxideEtoposideFluorouracilFosphenytoinFrusemide or FurosemideFurosemide may enhance the ototoxic effect of Cisplatin.ModerateMonitor for evidence of ototoxicity during concomitant therapy with cisplatin and Furosemide.Gallium NitrateGemcitabineGentamicinHydralazine (HCl)Coadministration increases the risk of peripheral neuropathy.ModerateClosely monitor for the symptoms of neuropathy such as burning, tingling, pain, or numbness in hands and feet. Either reduce the dose or discontinue in patients who develop peripheral neuropathy.IfosfamideIfofasfamide may potentiate toxicity produced by cisplatin.ModerateSerial audiograms is advised.MannitolNetilmicin (Sulphate)PaclitaxelPodophyllumThe risk of peripheral neuropathy may be increased during concurrent use of two or more agents that are associated with this adverse effect. In some cases, the neuropathy may progress or become irreversible despite discontinuation of the medications.ModerateCaution is advised during concomitant use of agents with neurotoxic effects. Patients should be monitored closely for symptoms of neuropathy such as burning, tingling, pain, or numbness in the hands and feet. Since the development of peripheral neuropathy may be dose-related for many drugs, the recommended dosages should generally not be exceeded.Propranolol (HCl)RituximabCisplatin because serious kidney toxicity or kidney failure may occur. TacrolimusTobramycin These interactions are sometimes beneficial and sometimes may pose threats to life. Always consult your physician for the change of dose regimen or an alternative drug of choice that may strictly be required.
