    Abstract:
    The dose-limiting toxic effect of high-dose (100 mg/m2) cisplatin is renal insufficiency. Hydration with furosemide- or mannitol-induced diuresis has been reported to ameliorate this toxicity. Animal studies suggest that mannitol may be superior to furosemide in this regard. Twenty-two patients with advanced neoplasms refractory to conventional therapy were treated with cisplatin at a dose of 100 mg/m2 every 21--28 days. Patients were randomized to receive 37.5 g of mannitol by 6-hour infusion with cisplatin or 40 mg of furosemide prior to cisplatin therapy. Hydration with at least 1 liter of normal saline was given prior to cisplatin. Nephrotoxicity (creatinine greater than 2 mg/100 ml, creatinine clearance greater than 50 ml/minute) occurred in 19% of courses in the furosemide-treated group and in 28% of courses in the mannitol-treated group. Peak plasma platinum concentration, terminal half-life, urinary excretion, and percent protein-bound plasma platinum were similar in both groups. The use of cisplatin at this dose schedule resulted in similar toxicity and pharmacokinetics when using hydration with either furosemide or mannitol.
