Hi - I'm sorry to hear about your brothers GBM. Carboplatin has a half-life of 1-2 hours initially, and can be effective for up to 10 days. Starting dose is calculated based upon a persons weight, height, and kidney functions. A typical dose for subjects with no previous treatment is 400mg/m2, at one time. Dosing may be increased, depending on the severity of the disease, and the patients reaction to treatment. As with most chemotherapy, this drug can suppress your immune system (bone marrow production of white blood cells). Also, the patient can become thrombocytopenic, and anemic, which is usually temporary. If your brother has a blood test, he might have an increased BUN, and serum creatinine, and liver enzymes may become elevated. Once treatment ends, all of these symptoms usually cease. As I am sure he knows, he can expect to experience GI upset and vomiting for the first 24 hours after dosing administration. Carboplatin is excreted primarily in the urine with 65% of the dose excreted after 12 hours and approximately 70% within 24 hours. All of this information is available on the drug label, or the FDA website. Has his doctor mentioned temozolomide? Good Luck
