Carboplatin is a platinum organic compound. Plain carbolplain appears as white crystals or powder, but it is mixed into a saline solution and administered through an intravenous feed. The feed tube is called a cannula, and patients usually receive the medicine over a 30 to 60 minute time period.

It is sold under brand names Paraplatin and Paraplat, and possibly other names. The full chemical name is 1,1-cyclobutanedicarboxylatodiamineplatinum(II).

The molecular formula is C6H12N2O4Pt.

CAS No: 41575-94-4
EINECS No: 255-446-0

Packaged as paraplatin, it comes from the manufacturer as 10 mg/mL solution. (The solubility is only 14 mg/mL, so the clinical product is close to saturated.) At the hospital, technicians and doctors sometimes dilute the drug down to 0.5 mg/mL. Sugar (dextrose) and/or salt (sodium chloride) are often added to the solution.

Doctors use carboplatin for lung cancer, ovarian cancer, testicular cancer, head cancer, brain tumors, bladder cancer, and retinoblastom.
