Abstract

The pharmacokinetic behavior of carboplatin administered by the i.p. route at a dose of 200 mg/m2 was studied during five courses of therapy in four patients with ovarian cancer. A regional pharmacologic advantage was noted with carboplatin administered by this route, with (1) peak peritoneal fluid concentrations 18-fold those in plasma, and (2) area under the curve (AUC) for the peritoneum showing a 18-fold and 6-fold increase over plasma AUC at 4 and 24 h, respectively. The mean residence time of total platinum in the peritoneum was 4.7 h. Approximately 10% and 40% of plasma platinum was protein bound at 4 and 24 h after treatment, respectively, whereas peritoneal fluid platinum showed minimal protein binding. Peak plasma platinum levels were comparable to those recorded in previous studies with i.v. doses of carboplatin. Peritoneal clearance of carboplatin in these four patients appeared to be less than that previously reported for cisplatin. Further studies are in progress with higher doses of i.p. carboplatin.
