Cisplatin, also known as Platinol-AQ® or CDDP, is a drug used to treat malignant cancer in dogs. The drug, which contains platinum, affects the DNA of rapidly dividing cells but the exact mechanism of action is not clearly understood.
Due to potential serious reactions, cisplatin should not be used in cats.
As with most cancer treating drugs, cisplatin is used in combination with other drugs to enhance its ability to combat malignancy.
Due to potential damage to kidneys, dogs receiving cisplatin are usually on intravenous fluids before, during and after the drug is given.
Due to the toxic nature of cisplatin, it is given in a hospital setting. The veterinarian and assistants should wear gloves when handling the drug.
Cisplatin is a prescription drug and can only be obtained from a veterinarian or by prescription from a veterinarian.
This drug is not approved for use in animals by the Food and Drug Administration but it is prescribed legally by veterinarians as an extra-label drug.
