• Beschreibung

  Carboplatin is a second generation, platinum-containing antineoplastic agent with significantly reduced nephro-, neuro-, and ototoxicity in comparison to cisplatin. It is effective in the treatment of advanced ovarian carcinoma of epithelial origin and small cell carcinoma of the lung.

• Chemische Eigenschaften

  White Crystals

• Originator

• Verwenden

  antitumor agent,

• Verwenden

  Analog of Cisplatin with reduced nephrotoxicity. Antineoplastic

• Verwenden

  Data on carboplatin production have not been found. Carboplatin is used in chemotherapy to treat cancer, and more particularly to treat cancer of ovary, embryonal carcinoma of the testis, microcellular carcinoma of the lung, neuroblastoma, and squamous cell carcinomas of the head and neck.

• Indications

  Carboplatin (Paraplatin) is an analogue of cisplatin. Its plasma half-life is 3 to 5 hours, and it has no significant protein binding. Renal excretion is the major route of drug elimination.
  Despite its lower chemical reactivity, carboplatin has antitumor activity that is similar to that of cisplatin against ovarian carcinomas, small cell lung cancers, and germ cell cancers of the testis. Most tumors that are resistant to cisplatin are cross-resistant to carboplatin.
  The major advantage of carboplatin over cisplatin is a markedly reduced risk of toxicity to the kidneys, peripheral nerves, and hearing; additionally, it produces less nausea and vomiting. It is, however, more myelosuppressive than cisplatin. Other adverse effects include anemia, abnormal liver function tests, and occasional allergic reactions.

• Manufacturing Process

  cis-Diammine platinum diiodide was reacted with silver sulfate to give cis-diaquodiammine platinum sulfate. This was reacted with the barium salt of 1,1-cyclobutanedicarboxylic acid to yield Carboplatin.

• Trademarks

  Paraplatin (Bristol-Myers Squibb).

• Therapeutic Function

  Antitumor

• Allgemeine Beschreibung

  Carboplatin is available in 50-, 150-, and 450-mg vials for IVadministration in the treatment of ovarian cancer, bladdercancer, germ cell tumors, head and neck cancers, small celllung cancer, and NSCLC. Activation of the agent occurs byaquation in a manner similar to that seen for cisplatin. Thepresence of the chelating 1,1-cyclobutane-dicarboxylateslows this reaction 100-fold and reduces the toxicity of theagent. The sites of alkylation and mechanisms of resistanceare like those seen for cisplatin, and the two agents showcross-resistance. The agent is widely distributed upon IV administration but, because of its greater stability, it bindsslowly to plasma proteins, requiring 24 hours to reach 90%bound drug compared with 4 hours for cisplatin. The agent iseliminated in the urine with a terminal elimination half-lifeof 2 to 6 hours. Adverse effects include myelosuppression,which is dose limiting. Other adverse effects include renaltoxicity, nausea, vomiting, and peripheral neuropathy, butthese occur much less frequently than with cisplatin.

• Pharmazeutische Anwendungen

  Carboplatin, cis-diammine(1,1-cyclobutanedicarboxylato)platinum(II), is a second-generation platinum drug. Its structure is based on cisplatin with the difference that the chloride ligands are exchanged for a bidentate chelating ligand. A consequence is that carboplatin is less reactive than cisplatin and therefore is less nephrotoxic and orthotoxic than the parent compound. Unfortunately, it is more myelosuppressive than cisplatin, which reduces the patients’ white blood cell count and makes them susceptible to infections. Carboplatin was licensed by the FDA in 1989 under the brand name Paraplatin and has since then gained worldwide recognition. Carboplatin on its own or in combination with other anticancer agents is used in the treatment of a variety of cancer types including head and neck, ovarian, small-cell lung, testicular cancer and others.
  Carboplatin is a pale-white solid showing good aqueous solubility. The synthesis starts with potassium tetrachloroplatinate, which is reacted to the orange [PtI₄]^2- anion.

• Biologische Aktivität

  Antitumor agent that forms platinum-DNA adducts. Causes intra- and interstrand DNA crosslinks blocking DNA replication and transcription. Enhances radiation-induced single-strand DNA breakage and displays lower nephrotoxicity than analog cisplatin (cis-Diaminodichloroplatinum ).

• Biochem/physiol Actions

  Carboplatin is a platinum-based antineoplastic drug that damages DNA by forming intrastrand cross-links with neighboring guanine residues. Tumors acquire resistance to these drugs through the loss of DNA-mismatch repair (MMR) activity and the resultant decrease in the induction of programmed cell death.

• Mechanism of action

  Carboplatin, another square planar Pt(II) complex, forms the same cytotoxic hydrated intermediate as cisplatin but does so at a slower rate, making it a less potent chemotherapeutic agent.

• Clinical Use

  This drug induces fewer nonhematological toxicities (e.g., emesis, nephrotoxicity, and ototoxicity) compared to cisplatin, and it is approved for use only in the treatment of ovarian cancer. Unlabeled uses include combination therapy in lung, testicular, and head and neck cancers.

• Nebenwirkungen

  The ultimate damage done to cells as a result of carboplatin use, however, approaches that of cisplatin. The plasma half-life of carboplatin is 3 hours, and the drug is less extensively bound to serum proteins. Excretion is predominantly renal, and doses must be reduced in patients with kidney disease. Suppression of platelets and white blood cells is the most significant toxic reaction of carboplatin use.

• Synthese

  Carboplatin, cis-diamino-(1,1-cyclobutandicarboxylate)platinum(II), is made from cisplatin by reacting it with a solution of silver nitrate, and then with cyclobutan-1,1-dicarboxylic acid to form the desired carboplatin (30.2.5.2).

  

• Veterinary Drugs and Treatments

  Like cisplatin, carboplatin may be useful in a variety of veterinary neoplastic diseases including squamous cell carcinomas, ovarian carcinomas, mediastinal carcinomas, pleural adenocarcinomas, nasal carcinomas and thyroid adenocarcinomas. Carboplatin’s primary use currently in small animal medicine is in the adjunctive treatment (post amputation) of osteogenic sarcomas. Its effectiveness in treating transitional cell carcinoma of the bladder has been disappointing; however, carboplatin may have more efficacy against melanomas than does cisplatin.
  Carboplatin, unlike cisplatin, appears to be relatively safe to use in cats.
  Carboplatin may be considered for intralesional use in conditions such as equine sarcoids or in treating adenocarcinoma in birds.
  Whether carboplatin is more efficacious than cisplatin for certain cancers does not appear to be decided at this point, but the drug does appear to have fewer adverse effects (less renal toxicity and reduced vomiting) in dogs.

• Arzneimittelwechselwirkung

  Potentially hazardous interactions with other drugs
  Antibacterials: increased risk of nephrotoxicity and possibly ototoxicity with aminoglycosides, capreomycin, polymyxins or vancomycin.
  Antipsychotics: avoid with clozapine, increased risk of agranulocytosis.

• Stoffwechsel

  There is little, if any, true metabolism of carboplatin. Excretion is primarily by glomerular filtration in the urine, with 70% of the drug excreted within 24 hours, most of it in the first 6 hours. Approximately 32% of the dose is excreted unchanged. Platinum from carboplatin slowly becomes protein bound, and is subsequently excreted with a terminal halflife of 5 days or more.
